Harley-Davidson Twin Cam Engine Is Not a One Size Fits All
Вставка
- Опубліковано 11 лис 2021
- The Harley-Davidson Twin Cam engine platform doesn't fit every person and every situation depending on what you plan to do with the bike. There are 17 years of engines out there and in all different displacement sizes which vary in price by year. Budget determines a lot of things depending on how much you are willing to spend for a used bike but each Twin Cam engine brings something different to the table. If you work on your own motorcycles and don't mind engine work and upgrades a Twin Cam 88 might be right for you. If you plan on buying a Harley-Davidson Twin Cam and only doing the minor maintenance. then having a shop take care of the rest a Twin Cam 96 or Twin Cam 103 may be a better buy.

Us Twin Cam owners owe a debt of gratitude to you Gixxer Foo.
I've learned a ton about my motor and the whole series of TC's.
Thank you! I really appreciate it! Makes me very happy to know we are getting the information out there to those seeking it for the Twin Cams!
@@GixxerFoo Absolutely, 5 years with my 103 Wide Glide, 130,000km and no issues except for replacing the cam chain tensioners a year ago cause the outer was a bit worn, fantastic engine👍
In my opinion, buying a NEW bike from H-D can also be a toss of the dice or a 'pig in a poke' , yes, you have a warranty but that doesn't make it feel good as you're waiting for what hopefully is the 'fix' at the dealer...we've all heard the stories, that being said, personally, the cost of a new one is a bit much for me.
The used market is plentiful with a lot of perfectly great bikes.
EDUCATE YOURSELF BEFORE YOU BUY
Your videos are a great help!
Thank you.
To my thinking the 88 is the best Twinkie as with all Twinkies the cam plate & oil pump should be changed to S & S . Bore the cyclinders to 95 or 97 you won't be disappointed ! One thing you never mentioned is the main bearing in the Six speed is gonna fail no matter what size motor you have ( I've rebuilt more than my share ) another good reason to get an 88 they all had 5 speeds ! That's my take & I work on them everyday in my shop !
That's truth that you won't be disappointed going with a 95 or 97 on a 88! Those bikes run hard with a conversion done to them, main bearings on that 6 speed is for sure one thing that always goes. It seems some bikes run forever with on the original main and other crap out early. Thank you for mentioning that!
@@GixxerFoo my fix is running Amsoil 75/140 severe gear oil in them seems to save that bearing & the viscosity I'd the same as 20/50 oil so no extra drag on the trans in cooler weather . It works !
Best thing I did to my 88 is bore to 95. With changing cams and adding the thundermax tuner I love the power it makes and I have no problem keeping up to most everything
Same
I agree. I love the Twin Cam 88. I've had two of them and had zero issues.
If you can get a great deal on a 88 I say go for it! Upgrade the tensioners, put in a descent conversion cam, and do the 95" kit. You'll have your purchase price plus $2,500 for all the parts. But... You'll have a very reliable and stout power package that will put most other twin cams to shame (with the exception of the 110). Great video!
You are by far my favorite UA-camr when it comes to used bike performance! You are right in my wheelhouse with your information.
I even purchased my 02 FLHTCUI because you gave me the confidence and info to trust the TC 88. I'm also thinking seriously about the Hammer Performance Cylinder and Head porting deal you talked about in your September 10 video. It sounds like a great winter project. My only issue is I also have a Gold wing as well as a 1948 Harley with a 80" Shovelhead in it, that are needing some TLC.
keep up the great work!
Duckman out
I really appreciate the support on the channel! Hammer is the best deal out there on getting a 88 bored out making one put some power to the pavement. The 02 is an awesome year with the Timken lower end, that's one less step if you decide to put a crank in it to stroke it.
I have a 02 tc88 Duce and 06 88 streetglide.
Your info is correct and you pretty much described my bikes issues perfectly.
It took me 2 bikes and alot of years to learn the knowledge you dropped in short video.
Good advice and i love the channel.
Thank you I really appreciate it! I hope it's helpful in getting those bikes straightened out! Those are really good years especially the 02 with the Timken lower end, 88's are solid once you get the cam chest sorted.
Love your show keep them coming learn a lot Thanks And ride safe
Thank you, we appreciate your support over here!
Always a lot of solid advice on your channel. I appreciate that you read the comments and reply.
Thank you for the support on the channel! I read every one and try and reply to all of them!
I love my 88 Road King. Plenty of power for cruising. I dont need a 6 speed tranny, and. Chaining cam chain tensioners are no big deal to change out, and cheap to do so its no big deal
I do the work myself
Doing the work yourself is the way to go and those older bikes are awesome, you can do anything you want to them!
i have a 2001 FLHTC. changed out cam plate,high volume oil pump 510 cams and jetted carb with #50. runs great.
Great video as usual Gixxer I have a 2015 RG great bike runs so good best bike I've had so far.
All the best from NZ 🇳🇿
Thank you, I appreciate it! You've got the post Rushmore bike, those are a night and day difference over the earlier models.
At 20,000 miles even a twin cam should not have cam chain issues yet. If they can afford it they could put in a good cam plate oil pump and a good gear-driven cam if the run-out is not too severe on the crankshaft and if you sell the bike you could use these as selling points so the owner knows that he does not have to do what you already paid for in order to make it more reliable.
I liked this video well done .I have a 2012 103 I have had little to no trouble love it .
Thank you! Those late model 103's are great motors, I would say Harley got that Twin Cam ironed out in those later years. Of course they got it right and then went to the M8.
I have a 96on my bike with the six speed, it still haves the original compensator, but I did take the auto adjuster off and on with a manual adjuster, this engine runs so darn good I don't want to do anything else to it but enjoy it, Thank you for your very helpful videos bro, have a blessed one👍👍👍😃
Thank you, that is awesome to hear! You know with that manual adjuster it might just save you the headaches with the compensator.
I had a new 2010 Heritage that I turned stage ll. Put the SE air box with stock cover, American Custom slip ons with the stock look. Installed a SE 259e cams and that bike ran like a charm It did have a compensator issue but not bad enough for me to change. I kept it until I purchased my 2021 Tri Glide Ultra. I did love that Heritage and every part added was HD. Not one aftermarket part. Beautiful bike and I kept it very clean. Sold it with 22,000 miles.
No receipts = it hasn't been done. I bought a Fatboy 2001, solid bike. Put a few thou into it now it really hauls.
Wud up Foo! I still say 01-02 were the best years with the timken. That picture of the cam chest with fragments of shoe is what my 2002 Night Train looked like when I bought it with 32k, even the metal sping tensioner blew apart. These years carb'd are my favorite. They are also the coolest running TC, 103's run hot as hell. 2005 was the year of the crap heads. Every year has it's issues but these early 01-02 years I feel Harley embraced QC and had the least amount of problems. The 5 speed tranny is bulletproof and a built 95" will outrun a M8 107 and keep up with the 114 up to 120mph, at least mine will. Harley's are like Lego's, super easy to work on, especially the carb'd years and proprietary tools used once pays for themselves. 30 years from now, I feel confident that when we look back, the early TC's will go down as Harley's greatest engine.
The twin cams caught a lot of flack but they really are some great motors, especially the early engines! Pieces of tensioner shoe and metal is the last thing you want to see in the cam chest, I hope you caught it before it ran through the engine.
I'd like for you to include the 110's more in your comparisons. You tend to neglect them a little. Love all your videos though!
Thank you, I do need to include the 110 more. The 110 was a special engine only on the high end CVO, the S models were the first time we saw it outside the CVO. The S models were really a steal with that 110.
I'm the second owner of a 2005 Custom Soft Tail Deuse.I got it back in 2018.Had no history at all.So first thing I did myself was the 10k full service on my on.After putting on new tires I did change out the factory cam plate and would pump to a upgraded high flow oil pump and a hydraulic cam plate and tensioners and just replaced the Prymary chain tensioner Other than that that's really all IV done.Other than the break shoes.She runs fantastic and until my baby let's me know something needs attention.I think I'll ride as is.
You've done everything that needs to be done on a 88, that's going to be a very reliable motor! Even with the time and money invested you're still way ahead of buying a new one.
Sorry I'm running behind I've been catching up, YT buried you for a little while but I'm back.
I have a 2000 twin Cam that I absolutely love with a ton of upgrades to the motor and drivetrain. I'm saving my pennies for an upgrade on my throttle body to the zipper throttle body and ECM setup. (Then I'm Done) 🤔
Although it's getting harder and harder to do I still gain respect from the big motor guys.
I always enjoy your videos thanks for the upload.
Welcome back! Glad you found me again! The 2000 models had the best crank and the Timkens, you've got a excellent motor to build on if you decide to put some power in it! Do you have Magnetti Marelli EFI and going to the Delphi setup from Zippers?
my 103 high out put in a 2014 ultra classic run strong with just a stage one, pulled up n down hills with not much shifting, had good low end torque, now did good on the highway just seemed like close to 80 mph i needed another gear to shift to, but there was no more gears left lol, it was a very trust worthy n reliable bike, i just traded it because i wanted a new road glide
One thing about a TC88 is it has the timken bearing and the tighter runnout specs but if you plan on going over 96" or so you have to swap the crank. Which I did when I did my 107 with Darkhorse MOW. It was tough swapping that crank because it was within a thousandth. Nice thing about the OEM TC88 cranks with Timken is you are usually able to go gear drive cam if you want because of the tighter tolerances on the crank.
Twin cam 88 cranks are awesome with the Timken lower ends from 1999 to 2002. 2003 on is when it went down hill with roller bearings and they started pressing cranks.
I have an 88 I've never had a problem just keep an eye on the cam and your good I've ridden it 1500 in a weekend
Thanks for the good tips. I have an 11 FXDC with a totally stock engine and 19K miles. I`m going to take your advice and over winter change out the auto tensioner in the primary. I worried about the compensator but since I have become a very easy rider, it should be okay for the few years that I have left. I use all Amsoil products, and have been very satisfied with them. You make easy to understand videos, and I`m sure you have helped quite a few people make informed decisions on maintaining their Harley.
Thank you, I really appreciate it! Getting the auto tensioner out will save a lot of head aches as the primary chain ages!
2014-2016 Tc103 touring bikes
That’s the sweet spot
My 08 96ci runs like a champ. Had the compensator wear out but I feel that was in its design. Easy fix.
96's are really good motors, compensator is really the only weak spot on those engines.
I have an 2011 Harley Davidson Eltra Glide Ultra Limited, with an 103 twin cam, stage one K&N air filter assembly, with an DK-catch can,CAT-Delete header pipe 2n1n2 cross over set up Cobra 4in Neighbor Hatters slip-ons,and I love it runs great.
That's a really nice setup, sounds like you've done everything right!
Maybe it's just me, but I'm extremely happy with the stock power output of my 04 RK...It has plenty of pull for my boulevard riding style, whether solo, or with a gal 150lbs or less. ;))
88's put down some excellent torque, they will pull where it counts for sure!
Good video, thx. I have a 96inch, 2012 Dyna Superglide, with 113K miles on it--never a wrench to the motor. I changed out my primary sprocket when new, from a 32-tooth to a 31-tooth. I ride slow anyway--65/70 and always thought the bike was over-geared. Really love the 31-tooth and the bike.
That's some very impressive mileage! They really do have some tall gearing which to me seems luggy down low, works good on the highway but changing that primary drive does make a huge difference!
Awesome video! I wish I would have waited now! I recently bought my first Harley Davidson!
Thank you, I appreciate it! Congratulations on your first Harley, what did you end up getting?
@@GixxerFoo a 2004 RoadKing with the 88! I've owned almost every other make of motorcycle! I got it for a great price! Very clean and a Fireman edition! I'm in Jacksonville Florida! Do you know of any honest and good mechanics near me? I would like to pick your brain about my motorcycle!
Great info boss
88ci as long as cam tensioner a been updated. I got screwed a 2002 flhrci I bought this past yr. Upgraded to a feuling hyd tensioner and a ss509 cam. My 96ci dyna has been perfect since day one 🦾
That's the main issue on the 88 is getting that cam chain tensioner upgraded, once that's done it's a dang near perfect motor.
I personally think the TC96 is probably the most under rated of them all. A friend of mine has a RK with one and it just runs great. My springer 88 is a solid motor since I did the cam chest and cams upgrade but it still wont pull like his 96 and he has that 6th gear. And both bikes are EFI mine with a good tune and his with factory tune. Now if a full dressed bagger was the bike of choice the 103 would hands down the engine to have. For my style of riding the 96 would be perfect. I hope the put a 95 BB kit on my 88 unless I run on to a screamin deal for a 96" bike. Thanks for another great video.
I have an 01 EG TC 88 Now 95" runs real good now SE Cams and Hydraulic compensator Camchane tensioner.98 hp not to bad
Not too bad at all on a 95 and they come on really quick too!
Yes it does I was very impressed did not expect it at all. Thanks for responding.
Bought an 02 fatboy with the 88tc i spent more than I paid for the bike in big bore, cams, ported heads, upgraded cam plate with oil pump and hydraulic tensioners and new chrome. Worth every penny.
It's for sure worth it! I mean it seems crazy spending more on the bike than what you paid but you're still in less than a stock new one. Just my opinion but I like an older bike with a bunch of performance work done over a new stockish one with bolt on parts.
lol i have an 06 i bought new. still has factory cam and tensioners.. i checked them still good. ive got 30K on this nightrain. ive been iching to tear into this for a couple years. i have all the tools just no time. i have new tensioners amongst other parts on standby when it needs it.
Damn you've got some serious miles out of the factory tensioner setup on that bike. There are some that will do that and then there were some of the later models like yours that just ate through tensioners in 15K miles.
good info - thanks buddy!
Thank you! Stay safe out there riding!
Good info thanks
No problem 👍
Great video Gixxer. Love my Twin Cam 96 w 54K. Want to have cams and cam plate done this winter. Looking at screaming Eagle parts. Good choice? Is 255 good for highway touring and distance riding? Great channel!
Thank you, I appreciate it! The 255 is the CVO cam, it's pretty but excellent for torque. It would be great cam with the mileage you have on your bike, easy on the valve train too.
I’m running a on a ‘10 ultra with the 96. Had the cams upgraded for some passing power. The compensator failed but it didn’t show any of the real obvious symptoms. The only symptom was during start up it wouldn’t fire off on the first stab of the button. Would kickback occasionally. Had the S.E. Compensator put in and she fires on the first jab and shifts much smoother. I never had issues finding neutral so I figured my compensator was good. All things considered I’m happy with my 96, and there isn’t a tc I wouldn’t own. Tensioners are cheap and every bike Ive owned has eventually became a stage two engine.
Twin Cams really aren't all that bad, they have some quirks but they aren't guaranteed to happen on every single motor.
What do you think of a 2010 police with the 103. Awesome vid again been with you from the beginning, keep em coming
They are great motors, they are the built like the late model 103's. They still have automatic tensioner for the primary but other than that they are solid motors!
2002 TC 88 is a good year to start with. It is the last year that uses Timken brg's. on the sprocket shaft not roller brg's. Manual primary chain tensioner.
Upgrade the cam chest with cams, camplate, updated oil pump hydraulic cam tensioners or even gear drive cams.
Then pull the heads and have a econo port job done. I would keep the bore at 3.750 (88"), stronger cylinders. No thin cast iron liner that you get with the 3.875 (95")
cylinders.
That's a great point and yes the cylinder walls were a lot thicker on those too! That's why if you elect to you can bore those cylinders out quite a bit or just over bore a little over time. You for sure can't beat the factory lower end they came with!
The 99-02 were the best lower end. Swap out oil pump cam plate do springs in the head for bigger cam. Valve job. Gear drive cams if you can. Bigger bore 95/97 Great performing engine. Of course make sure it gets enough fuel.
That's one of the most solid engine combinations out there for a Harley big twin. You can get a nice 88 pretty cheap and if you do the work yourself it's hard to be in it any better than that.
I own a 2003 Lowrider with the 88tc with 88,888 miles as parked Wednesday night. tensioners were done at 43K and also have a 2014 Street glide special with the 103HOtc with 19,981 miles as parked Thursday night The twin cams are great both pull tremendous.
You've got some awesome bikes and the best of both worlds! I'd love to get a touring bike for the long haul myself, sound like both bikes see some serious miles too!
@@GixxerFoo Thank you. and bikes are made to ride ,I didn't mention that I bought the 03 in Nov 2014 with 13,500 and bought the 14 in Nov 2020 with 7821 miles...so yes serious mileage . And a Resident of NY with terrible winters
The early twin cam did have the better crank setup that wasnt pressed together!! I think the best bang is the 14 or newer models. Lastest ecm and wiring that carries over to the M8
You can't beat those first generation 88's lower end, Kevin Baxter always takes them down and converts his engines back to a Timken lower for his customers.
My 124" has the timken upgrade with my S&S flywheels!! I used TMan for my lower end upgrade line bore for the timken and installation of the crank.
Hello Gixxer, good video, as always!, and I "Liked"-it. Please refresh my memory, what year did the TC-103 come out? Also, with the 2007 and 2008 TC-96 engines, the cranks often came with serious run-out from the factory. This was a financial problem for the MoCo, and so they changed the allowable running spec. on cranks to .012" in order to stop having to pay on warranty claims! The cranks and the integrated spring-pack compensators on these models were often pretty bad, Gixxer!
I don't they exactly fixed anything other than upping the crank spec, there were some bad cranks right out of the factory for sure. The 103 first appeared in 2003 on the Screamin Eagle models, then it was on police bikes and select touring models. In 2012 they put the 103 across the line finally though.
I have an 88 tc, been running strong for over 6 years now, not one issue. It has a 2 into 1 pipe, jetted carb and open filter. I've owned many rice rockets back in the day and they were all fast as hell. There's just something about the 88, it just seems to pull really good for what it is. I've never had any issues keeping up with the 96, 103 etc. I've thought a couple of times about going with a 96 or 103, but I just feel it'd be a waste and not really worth the money.
What the 88's lack in horsepower they make up for in torque, they are really strong engines.
@@GixxerFoo yes sir, keep up the good work with these videos.
Had a 07 Super Glide with 96 bought new. No issues had about 14000 miles on it. B4 I sold it.
96 is a good motor, it's really solid they used the same compensator from the 88 the first few years and it didn't like the torque of the 96.
I'll tell you what is good when you buy a 120r strip it all out and fill it up with S&S gear then you'll have a cranky tractor love your work cheers from oz✌
Those 120R's are mean engines right out of the box, you can get even more with a cam swap when you do the gears too!
I've had all 3. 96 FXDC (stage 2), 96B FLSTC, 103 FLTRU and now an 88 FLHR all stage 1. The 96 stage 2 in a Dyna is a beast. 103 is by far the best in the touring model. Now that I have the ol' 88, it's going Cholo and will eventually get a stage 2 and that's about it. Yes, it took 4 bikes to figure out what I really like in a bike. She'll get broke open this winter to check the cam chain tensioner and if it looks bad, the Cam upgrade will happen much sooner than the pocket book says. The 96 and 103's all had Comp issues around 25,000 miles. Had I known the root cause was probably the auto tensioner, I'd have swapped it immediately.
I will say, that factory 103 was a strong runner and is probably the best TC they made.
A set of cams in a 88 really pours on the torque, good set of cams in your current 88 will be about perfect for the build you got going on. That sounds about right for compensator fail, as those primary chains stretch the auto tensioner takes up all that slack. Eventually something has to give and it's usually the expensive parts.
Great vid. I own, or did own a 16 103 TC. She was great at first. But, suffered from terrible blow by. Added a catch can to stop all that oil from hitting my pistons, then realized how bad the problem was...
She kept filling up every few hundred miles. Decided to have her torn down and upgrade the cylinders, and go from chain to gear drive HO cams. Found out my runout was at .0010... Not at all good. Regardless of what HD says.
After a tear down I realized she was sumping pretty bad from the all the oil in the crank. Bad flywheel was likely the cause. I'd say if you're considering any HD long term, shore up the crank, weld it or add a timken. Other than that, the 103 was good to me.
It's unbelievable that Harley says .012 is within spec in the bike, that's waaaay to much. Damn that sucks I hope you were able to get all that sorted out but it sounds like you sold the bike.
@@GixxerFoo actually, I decided to build her out instead. Replaced the 103, with and S&S 124. Along with an S&S flywheel, which I had welded, then added a timken. She's not going anywhere!
I have the first year Twin Cam carbureted 1999, and the last year 103 HO, fuel injected. Love them both. BTW, I had no idea that the late model 103 HO's still had the self adjusting primary chain tensioner. Time to bust the primary open and make a change!
They carried that automatic adjuster over onto the M8 as well, they work great early on but as the bike ages they become a real problem.
I love my 88 an still take it to the shop....other than fluid changes I would just mess shit up😳😒 the man I bought it from told me everything you have said... I ignored it because I was selfish and wanted to ride it for a little while before I took it to a shop. Chain cam tensioner bit the dust. Luckily no damage to the motor🙌
Good thing those tensioner pieces didn't block the oil passages, that would of made for a bad day!
@@GixxerFoo yessir you know the procedure screaming eagle cam chain tensioner and oil pump. Luckily my mechanic is John Maxwell and he and his staff are awesome and tried saving me money everyway they could. Great guys and thankfully I didn't have to take it to Harley Davidsons shop 😳 I should've had it checked right away though no doubt cause all the money repairing it could've went to upgrades on the motor but hell that's the way she goes bud. Love the channel. I've gone to it alot the past year and added you to the boobtube guys I like such as John Maxwell and Shadetree Surgeon just to name a couple. Cool knowledgeable guys without the arrogant attitude towards us less knowledgeable cats. Preciate it 🤘
I'm looking into a clear derby cover for my tc88. Any recommendations by chance?
I think it’s important to have a service history receipts. I have a 14 110 Limited runs really good no problems just had to change the water pump Warranty took care of it. It’s still 110 stock cams freshened up the top of the motor I went with some higher compression pistons. Lots of torque great cruiser.
50,000 miles problems none. Amsoil
The 110's make some serious torque, the water cooled heads are awesome on those twin cam motors. They had some issues with the plastic housings there for a while but seems like they got that worked out.
That's the same oil I run too, it's really good stuff!
I feel the 11,12,&13 103 are the better choices for a twin cam. However I would like to try a 2016 with the wet heads for the heat…
Those twin cooled bikes make a huge difference in the radian heat you feel, I've got a friend with a new M8 that is twin cooled.
I would like to have because I don’t have any big expectations of horsepower but I do like to work I would like to get another 88 inch and do a 95 inch kit with the cam. I had one before was just amazing torque it was a 2000 road king that would do wheelies. The way I ended up with the 95 was under warranty when the motor scattered at 5000 miles from a cam bearing
Awww man that sucks dropping a cam bearing like that! They are some fun bikes to ride and honestly not bad at all to work on.
My bike is a TC 88B. It has served me well over 19 years. A little over 64,000 miles at this point. I had the cam upgraded immediately after buying the bike and had the Screaming Eagle cam plate and tensioner kit put on a few years ago. I guess that I should save my money up and get the primary tensioner replaced by a pro as soon as I can.
On your 88 it would have the manual primary tensioner, so no worries on changing out a automatic tensioner there. Sounds like you've done all the right things to your bike!
People hate on the B but if it runs then who cares
I just bought a 96" last spring with 30,000 miles it cost about $1000 to take care of worn parts. Great motor i put 10,000 miles on it before winter hit here in michigan.
It takes some money to get a used bike back into shape a lot of times but it's worth it. Dang you did some serious riding to get 10K put on that bike, riding in a Michigan winter would be a little rough!
@@GixxerFoo i rode a sporty for a couple years and some commuters before that. So getting my first touring bike was exciting. Last week I rode a couple hundred miles and this weekend snow so I put it up.
hey that white tail section over your shoulder behind you... what sport bike is that from? AND what imports do you have lurking around? I have some yamaha and Honda myself .
That's the number plate off my old flat track bike, pretty much everything on a framer flat track bike has to be made. There's not off the shelf parts for those lol. I don't have any metrics anymore these days, just a couple Harleys.
You didn't mention the 120" screaming eagle Twin cam. I know it's a bolt-in motor but this twin cam is a great motor. I would love to know your thoughts on this motor.
Exactly what I was looking for. Thanks again.
Glad I could help!
I have a 13 street glide 103 with stage 1. It had just under 19k miles when I got it now almost 20k miles. from the original owners husband and wife who did a few long rides the first few years then he really only rode it to work because she decided she didn't want to ride anymore. He just past so I only got limited information from 1 from the person who lined up the sale and 2 the Harley-Davidson dealer ship where he bought it and had his work done. It has the Cobra full dual exhaust system with the crossover pipe oval air cleaner. Coming from a 2000 kawasaki vulcan 1500cc. The 103 has much more torque and feels comfortable on the highway. I plan on doing S&S big bore kit some time down the road and many other upgrades. For now I'm just looking at doing wood TW 222 cams want to know what the differences in 555 777 and so on. I plan on getting the kit from wood so pushrod lifters all that my problem is once I install everything how is the bike going to run tell I can get it in to be tuned because there about 5 weeks out on getting bikes in to tuning. I know down the road I'm going with a different cam setup after doing a big bore kit and all that but that's probably not going to happen for the next two years I just want to get as much out of what I have now and enjoy it more. It's personal preference but I went with Amsoil transmission primary and oil with there filter and changed out the plugs with NGK that it calls for personal preference and Screamin Eagle wires. I personally prefer to run recreational fuel the bike seems to have much more torque and throttle response over normal pump ethanol mixed gas. I really want to get the cams in sooner then later but if it's best to wait until I can get it turned ill just have to wait.
Ive inquired about several 1999-2006 twin cam bikes in the last year and every single one of them have never had the motor opened up mainly having the tensioners replaced/upgraded. Some of them were absolutely beautiful bikes but with 30k plus miles and on the original tensioners its a ticking time bomb. And of course when I mention not being interested anymore because of the tensioners the seller gets super defensive saying the bike runs great. Im like yeah im sure it does until there's problems. People have reported faulty tensioner shoes at very low mileage on these years. Id hate to buy a bike to spend 1k doing the cam work. Didnt mind my 2013 streetglide 103 but it wasn't quick by any means. Always ran awesome. Have no experience with bikes newer than 2013.
Yeah they will run great with chewed up tensioners, that's the kicker is you never know it until the oil passages plug up and shell the engine. Now you can pick up those 88's very reasonable with the intention of replacing the tensioners.
I bought my 09 96ci heritage with less than 12k miles on it for $6700. came with an extra windshield an extra seat, stage 1 tune and pipes, highway pegs and crash bar. I have done so much to it and have a ton of parts waiting to be installed including a darkhorse comp eliminator, baker manual tensioner, thundermax ecm, and velociraptor air intake, and a few other odds n ends
That's awesome! You got a good price on that with all the accessories, sounds like you'll be staying busy this winter!
@@GixxerFoo thats the problem bro, too much to do and only one Blaze lol
Never had issues with heat from my 99 rk. Definitely feel less heat then my old kz1000. Even when it’s 95-100 degrees outside.
I love those old KZ's, those are some fun bikes to ride! Truly from the era where horsepower exceeded brake and chassis technology. 99 Twin Cams had the best lower ends with that Timken setup, easy to get some fuel in those motors with the carb to cool them down a bit.
@@GixxerFoo I had a 2001 carbureted RK. It had the S/E intake, pipes and ignition module plus the carb kit. Never any overheating problems, not even getting stuck in Chicago traffic when it was over 90°. And no oil cooler.
I have often heard torque and horsepower treated as if they were independent quantities, In fact, brake horsepower is derived from a calculation that relies on torque: BHP = Torque X RPM / 5252. Defined simply, multiply the torque by the axis’s rotational speed per minute (RPM) and you’ll get the engine’s final power output. my guess is that when you talk about torque in positive terms, you often mean low end torque which is the same thing as relatively a lot of power (hp) at low revs.
88" mod to all bore 95" rev happy power house -88" is the best bang for the buck im an EFI guy and I run Thunder Max due to my extreme build
95's run very strong, that short stroke comes on in a hurry!
@@GixxerFoo ive ridden alot of built motors bit something is special woth this build on a softail is the golden build its the perfect balance of high trq and it walks the line of being touch but not get out of hand
Love my 103 dyna.... considering just a bolt in cam- but do you have to upgrade the cam chest, oil pump, bearings? I don't want to go down a $$ rabbit hole??
You don't have to upgrade the oil pump and cam plate to do a cam swap. It's really one of those just while you're in there it's the time to do it, especially if you're paying someone to do it. I would however recommend some new inner cam bearings, those are inexpensive and you're already there. It's just good insurance with a new set of cams.
For someone who knows zip about bikes would solid mounted double sprocket spindle solve problems , yes then it would be a double chain
There is a gear drive conversion for the Twin Cam bikes, but the tolerances are very loose in the Twin Cams. They went with a chain drive on the cams to compensate for the loose tolerances. They press the cranks and they don't true them anymore and instead of running a tapered roller bearing with proper backlash setup it's just put together with roller bearings theses days.
I have a 06 street glide 32000 miles that being said I would like to upgrade the motor i have a chance to buy a brand new in the box earlier 2000 cvo 103 motor is not real impressive in stock form I think a good Cam would Wake it up tremendously. Your thoughts on this will be gratefully appreciated
What's your pick for the Twin Cam engine, which one do you like the best and why?
Lower end 2002 Twin Cam 88, Top End late model 103 (Not a wet head or shower head as some call it)
I’m personally a big fan on the 06 Dyna with the 88 six speed AFTER upgrading it lol. Updated bottom end, bigger injectors with the 88. It’s a solid builder, just garbage until it’s rebuilt.
@@DuartesGarage you're a man of culture
Iv had good luck with my 2011 and the 96ci TC engine. 👍
Big bore 88, especially on the 06 fxdb ☺️, with an open primary 👌. I agree the 103 is just right.
Hey Gixxer, which was your favorite model? Mine was a 1986 750 limited with the dry clutch. At the time I was younger, lighter, and had access to spending cash and the Suzuki and Ducati were my favorites. I had the GSXR 750 limited and a Paso 750 limited, which the Ducati was bought by mistake. I actually wanted the blue version and the dealer (House of Wheels, circa 1980's Houston) had all three in stock (Red, Blue, and White) and when I went in to buy the blue, they sold it to someone while I was sitting there waiting for my paperwork to come back. So they sold me the limited, the white one, for same price and I am so glad they did. The memories that bike gave me. I'd still buy one if I had the cash. But now I'm 340 lbs and 6'5" and can't ride these classics. lol
I've had that happen before, had a bike sold out from under me on a paper work mix up lol. I am for sure a low rider fan, I like the original shovel head version but the Twin Cam 103 version almost looks just like it.
I buying a 2001 Electra glide tc88, it's been bored to a 98,bigger crank, hot cam, bigger pistons. I'm buying off my pops who had the work done about 10k n motor work I'm getting for 7k, good price I feel?
It’s obviously the 103 HO Because of the better cams & tiny increase in compression.
The 103's run really good once you get a flash tune done and put some fuel in them. That gets the heat down and the bike doesn't feel like it's starving for fuel all the time.
@@GixxerFoo
Yeah I got 108 hp 116 TQ with stock pistons Andrews cams
You are dead on with to 07 and later TC96 compensator and auto tensioner issues. I eliminated my compensator with a Vulcan sprocket and swapped my tensioner for a Drag Specialties manual 5K miles ago. Unfortunately, it was too late for my transmission bearings. Brought my 07 FLHTCU to my mechanic for tires and regular maintenance and he found they were shot.
As far as my run out, when I upgraded the pump/plate and cams, I had . 0045 after 63K miles. I guess I should count myself lucky on that issue.
You definitely deserve an "Atta Boy" for explaining that issue and the possible fixes. Thank you.
Thank you, I appreciate it! Sounds like you've done everything right with the upgrades! It makes a big difference on those motors when you get the factory flubs sorted out.
a friend of mine had a ultra classic . early 2000s, not sure which year. it had a 95" or 98" kit on it with cams and S&S heads. that thing ran . he loved it. sure there are faster bikes now but how much faster does one want to go? ticket fast or go to jail fast ? lol you can always upgrade a 96" to a 103" easy too if one wants too if i remember right and if you going to do that you could go a head and upgrade it to a Timkin main bearing too. it will take more time and money though. to me the beauty of the 103" is you can upgrade that with no machining to a 124"!! *rubs hands together with an evil laugh* lol though if you do that one should definitely upgrade the main bearing and any other stuff while they are there. it may cost you a wife and your soul but meh its a 124"!! lol. see this is the bad and good thing about Harleys sooo many options/ways to sell your soul lol. good vid
Thank you, I appreciate it! Going to a 124 is super expensive but for sure you'd want to get that crank done and get it converted back to a Timken setup. Lol that's for sure beyond what the stock crank is going to handle.
2002 and earlier had the timken bearing in cases .
Early fuel injection 2000 yr was junk -
✊🏻👍🙏👌
Yeah I highly recommend staying away from anything with the Magnetti Marelli FI system, there's any parts or support out there for that.
@@GixxerFoo yup I know a guy who broke down in Yellowstone Park at dusk on a 2000 ultra with that injection and problem.
(Sturgis run )
Happy thanksgiving 🦃
I call you out... xD do a video of the CVo 110 SCREAMING EAGLE please
I do have a 110 video, it's a bit older but I want to make a new one on the 110. I've had a lot viewers express the 110 is often left out. Here's my older 110 video ua-cam.com/video/R544QkfXX3w/v-deo.html
Not sure where you found it, the thumbnail photo is my "happyass" bikes twin or might be mine b4 I got it
That's awesome! I actually saw it on a Harley-Davidson forum in a thread I was reading that was posted many years ago.
Why didn't you talk about the screaming eagle 110 ? I just bought one and it seems to get skipped over a lot .
The 110's are really good motors, they just got a reputation for running hot but a flash tuner will fix that. Once you get that fuel in the bike it makes a world of difference.
Talk about the 110 twin cam screaming Eagle.
How do you determine if your 103 is a high output or regular output motor (2016 Fltr)?
2014 and up touring bike are the HO and I believe the Softails, Dynas are all HO 2016 and up.
So my 2007 96 inch Ultra Classic 6 speed EFI doesn’t have the cam that Grenades the motor ? I’m the original owner. Thanks for your time .👍
The cams are good on those motors and they had the hydraulic tensioners. Main thing with the first few years of that 96 is going to be the compensator, they had some issues but it didn't fail on every bike.
@@GixxerFoo
Thanks!!
I like my 2001. Crank pinion runout within .001”.
I don’t think I want the later years with up to .012” out of true.
I’m not racing, just touring on a dyna.
Carbureted.
Drop some gear drive cams in and done.
If I want to go faster I have a ‘92 Honda VFR750.
Dang that's almost perfect run out, those timken lowers make a huge difference!
@@GixxerFoo
I was overjoyed when I measured it.
I can't imagine reading .012".
Wouldn't even need a dial indicator to see that. lol
I have an 88 (original owner) anything I should listen for to know if I'm starting to have an issue with my cam tensioner ? I have like 40k (speedo didnt work for a while n didnt count millage so) unmolested so hate to open it. If have to than yes cam change
Usually you won't be able to hear anything, if you can something to probe the case and put your ear up to it you might hear some bad noises but by then it's too late. Best thing to do is pop the cover and just have a visual inspection.
Thanks for your time, watched your cam swap so when I get the money I guess I'll do a cam seeing how it will be open. Thanks again
How do you feel about Love Jugs?
They really drop the temperature on the motor, they are great if you ride in traffic quite a bit. Biggest complaint is that it ejects that heat onto you're right leg, not a huge deal when it comes to cooling down the engine though.
I love my 2014 Street Glide 103.
I’ll never sell it
Buy an 88 ci make it 103. Port the heads and trash the cam chain, cam plate. Gear drive is the way to go. My bike the crank shaft made it to 9,000 miles. Check it before the whole engine goes down.
What combo would that be ? I think you have to put a 4-3/8 fly wheel in or bore the cases for 4” cylinders.
Yes you'd have to put a stroker crank in, that's what the 103 on Scream Eagle bikes were. Basically a 95 inch kit with a 4-3/8 flywheel.
It really helps if you're able to do the work yourself, if you're paying labor that will get expensive in a hurry.
Funny. I'm literally sitting beside my fxdf, Primary off, Staring at my compensator and clutch. I had a weird rattle that would go away when i pulled in the clutch, I assumed it was the IPB but now that its off, my Chain is super loose. Now i'm faced with a dilemma..... Do i pull everything off and check the IPB or do i adjust my chain and close it up and test it.
Thats why im watching youtube lol. I'll probably watch some Family guy next, then pull everything off.
Can't beat some Family Guy, lol love that show. I would try adjusting that chain to proper slack first and see if that takes care of it first before going deeper. A chain that's too loose or tight can cause some weird noises.
There are so many expensive cheap parts in a twin cam motor I could not take one for free because I cannot afford to fix all of Harleys deficiencies for Harleys price they should not have used any cheap parts.
“Not a bad twin cam out there”………..Every one of them grenade without upgrades. Ohhhhhhkay!!!! I had 88 96 and 103. All had those issues you mentioned, why does Harley charge a premium, but have shit designs, with no power? I’ve always wondered that.
The motors are really solid once you get the factory flubs out. Just my theory but in the 90's Harley couldn't keep up with demand on the production line and the Evo was likely too reliable. So with the Twin Cam they designed it to be assembled more quickly and the parts cast and machined with speed on the line in mind. Also failure points engineered in to generate demand for parts and service, just my theory though.
@@GixxerFoo I’ve read that on a lot of sources. Those old timers were mad. I had a 2006 Electra glide standard, and that thing broke real quick. It was such a cool bike too, saddened me 😂
Power is relative. In absolute terms, an 88 is really slow, but having the power of H2 R is useless. Who can go and maintain 400 km/h speed on a public road? Power means nothing on public roads. Low end torque is far more useful in those scenarios, and an 88 is absolute king if compared to any revvy bike. I've met people who have ditched their crotch rockets in favor of torquey motors that can handle 2 up easily. Power just means something exclusively in the racetrack.
Damn shame that we have to be concerned about concerns like these... i can honestly say averything that has the HD bar and shield logo on it is gonna give you problems as they're ALL prone to failure.
It truly is a shame and no matter what it is there is always something to be sorted out.
@@GixxerFoo 🎯
Why not run a belt primary
Yep that SE110 moves an ultra around pretty darn fast, easy to slip over 100 if not using the cruise......just doesn't sound right 70mph in 6th
How do you find an 88 with a good price? I've got a 96 that was at least $3000 less than I can find an 88......used bikes have gone nutz
Inflation is making the prices on everything crazy right now! If you have a used car or bike it's a seller's market right now.
If the twin cam has been maintained they will go 80000 miles with no " updates". I proved it.
They sure will and keeping up on fluid changes and just being vigilant with those motors is the key!
Gixxer what do you think about Red Line oils? I use it in my car n like it in that, I bought a 3 hile change kit in Red Line for my scoot, hope I get the same results as in my car. I been holdin off to do all my work at once, probably get on it next month. lookin forward to bringin it to life just hope my run out is ok lol
I hope your run out turns out good! Red Line is in my opinion the best oil out there, I'd argue it's better than Amsoil. It is expensive but its is well worth the money and trying to find a supplier.
@@GixxerFoo cool thanks bro
💕💕💕
Gra👵 said give five 👍👍👍👍👍
🛑🛑 Gix….Having owned a few 110 Twin Cams; and that I’m currently riding a 110; pushed up to 117 Stage IV…..
The 110 Twin Cam is an “outstanding motor”. I would highly recommend a used 110, within reason.
Just food for thought.
😀👍
Those CVO's with the 110 are an awesome buy used, when you look at retail on those bike new and what they are selling for now it's no brainer. They command more than other bikes but you get a lot for you money on a used CVO.
How do u know if a 103 is h o? Anything after 14?
Rushmore bikes, 2014 up for touring and I believe 2016 and up for softy’s and dyna’s.
2014 and new touring bikes and 2016 Dyna and Softail for sure. Usually says HO on the air cleaner cover, most Dynas will have a open air cleaner as well.
