One thing i didnt mention that I thought I had. Much of the extra power made by the S&S and Zippers cam could be due to another factor...to properly tune with a cat installed in the headpipe, the AFR should be a bit leaner than without to avoid overheating the cat. The leaner mixture could also have created an increase in the numbers. All this said...the manufacturers test their products and all we can assume is that they published the highest number they obtained in their testing with the stated equipment. Main point of the video is to illustrate again, how the cam specs effect the final performance and characteristic of the curves, and what each means. Hope you enjoyed it.
Sure did!! Hey Kevin...would like to call when your "not busy". LOL We are all busy...but have a question about the"old" fuel pack with the mode button and settings. It came in a Heritage I put based a while back. Didn't know it was on there until a few days ago.
Learning a lot about Harley M8's, You, appear to be meticulous Engineer / Mechanical Engineer, I am 81 yrs. old & Harley Rider/ builder, and impressed! Have a great day! Kevin I Spend many hours watching learning, listening, and remembering all the wrenching! Thanks for the sharing!!
Personally, I'm going with the S&S for my 107. It offers a huge boost in torque and power over stock, but as my only mode of transportation and something I rely on 100% of the time to get anywhere, I don't want to overstress the shit out of the engine and worry about it blowing up after 30k miles.
I started following you about 3-4 weeks ago. For a guy who finds things like this incredibly interesting no one explains it better than you. You are a wealth of knowledge Kevin. Keep up the awesome work
you Kevin Baxter are the Harvard professor of HD engine theory and utube schooling.you explained and have shown all of us mechanics and non-wrenches, what is up in the world of cams for our bikes.THANK YOU.
I recently put the zippers 468 on my 114 with vance and hines power duels with harley street cannon slip ons. This really woke up the bike. The shop that tuned it said at the very top of rpm range it shows bigger injectors and air clean would provide better performance at that range. I bought the cam because of its mid range performance for cruising and also for using the bike in slow skills practice. Your explanation are great and if I get in your part of GA hope to stop by.
Kevin...thanks for that break down. Looks like I made the right choice in cams 7mos ago. I have a 2018 Road Glide Special. When I bought it I had a HD Stage 3 build done basically bumping it up to a 114. Everything used was HD except for the headers which were FuelMoto Jackpot 2-1-2. I used the Screamin' Eagle 4" Street Cannons & Screamin' Eagle Street Tuner. I ONLY went this route for warranty purposes. Respectively the dyno showed 113.84ft lbs tq and 109.24hp. This past April my factory warranty expired and I decided to install the Zippers 468 cam, S&S adjustable push rods, S&S billet tappet cuffs and S&S high flow oil pump and cam face plate since I was already inside the chest. I swapped out the mufflers to Vance & Hines Torquer 450 then had it tuned using PowerVision. I ended up with 140.33ft lb torque and 122.94hp. It is a beast now. A torque monster that hits hard at about 2750rpm all the way up through 4000rpm. I mean it is a rocket strapped to your ass when you twist that throttle!!!! And the "thump?" Yea...you can hear it!! Lol. Can't complain with the performance of this cam. This bike now has 50,500mi on it and gets ridden!!!! I don't beat the day lights out of it but she's also not treated like a queen either. Definitely recommend this cam to anyone who wants a good bump in torque.
I wish you were closer! I want you as the only person that touches my bikes... you are very well versed and a master of your craft. I enjoy your videos quite a bit!
2018 FXBB with a TBR 2 into 1 for the past two plus years. So I've decided to S2 and have been researching torque cams. Best and most helpful and detailed video so far. With my intellect I did have to watch it a few times to get things straight in my head but ended up being a really helpful video. Thanks very much, top stuff.
I went with an Andrew's m460 in my 107, it's a cam that seems to get no love. I think it goes great and with only 2 degree overlap and 20 degree intake closing I'm still getting great fuel economy. Everyone loves the 475 but it seems to drink the fuel and only really makes more than the m460 above 4500 rpm.
12:10 Good to know! I'm in the minority of thinking my FXDR's exhaust and air cleaner actually look fine on the bike, so I left them on. Before dyno'ing the bike the Dealer URGED me to get a "less ugly" exhaust & air cleaner combo and showed their Screaming Eagle and Authorized Dealer Catalog (S&S, Vance and Hines, etc.) and said I'd be missing out on big gains if I stayed stock...I ignored their upselling attempt and bought an Intake Manifold instead. Imagine their surprise when my bike dyno'd higher than most other stage 2 114's they had done... 125HP/128TQ S&S 475 Cam Chest Kit with Dynojet Powervision
Excellent video explanation of how critical cam choice is. The M-8 motor HP is held back by low RPM operation. In your video building torque earliest and holding onto it longest, makes a very streetable, enjoyable bike to ride. Good Dyno numbers for a stock 107. Excellent video Kevin.
Exhaust opening point at BBDC is an important factor in torque production. Lobe separation angle is also important. When looking at intake close as a torque factor lobe intensity is needed because we don't know the actual intake close, just at a .053" lift. Compression bleeds whenever the valve is not seated on the way up on compression stroke. Lift is relatively not significant when comparing these bolt-in cams with stock heads.Just my humble opinions
maaaaaaan after seeing this, i wish i went with the zippers 468 instead of the fueling 465 cam that came with my race kit. id like to swap cams , but after getting the bike tuned by the now retired "Doc." from Docs Performance with a TTS Master Tuner, I feel like im stuck. He did a Great job! 33k miles on my 2018 Road King Special ... My next venture would probably be a 124 sleeper kit from Zippers... ITS ONLY MONEY LOL
Or a 124/128 kit from us....those are pretty good too. LOL. Thanks for subscribing. Docs a great tuner...stick with what ya have until major changes become an option. thanks for the comment.
Can’t go wrong with the 124 kit. I have it on my 2019 street glide with the Zippers 468 cam, tab performance slip ons, khrome works header, SE intake, SE adjustable pushrods, Fueling cam plate with lifters, S&S tappet cuffs, and TTS tuner. I couldn’t be happier with my setup.
Hey Kevin I have a 96 to 110 build and I’m gonna be running a woods 999-6 cam with .590 lift. On the fence about running roller rockers or not or just set of new S&S standard. Iv heard some people say yes and others say no and wouldn’t run until around.630 lift.I appreciate your videos and have learned a lot from them
Thanks for all the knowledge fixing to go to the garage and put my compensator man of war in my 2009 Harley-Davidson night train thanks have a good day
Kevin U are incredible. U made it easy for me to understand these numbers. I almost wish u could’ve included the woods 22x. But thank u for all u do u are a godsend
Thank you for the kind words Chris. Much appreciated and glad you find value. There are more cams to compare and other factors to consider when choosing...such as wear and tear on the valve train. The numbers matter and with each, pros and cons. Stay tuned....
Love your videos. Very informative. Your opinion on a low to mid range cam for my new 117 low rider st. Also, your opinion on using the stock cam plate, oil pump, lifters, and inner cam bearing. I will be using a fuel moto dyno jet tune. Thanks for you help, and keep those great videos coming. It’s very helpful to have someone in the know, offering opinions as compared to the usual tube video personnel.
Great information video. I’ve been Cam Hoppin’ on my 131 M-8. Had a Zippers 468 in it for awhile. I just put in T-Man TMP-2652. It seems to have more power but it’s a gas hog...even without getting on it my best mileage is 33MPG. Seems to run hot too. I installed a Dakota Digital Gauge set at the same time. I’m getting head temperatures as high as 327 degrees on the freeway. The plugs aren’t white so I’m not running lean. They seem to be right. I don’t know what it was before I had the temp gauge but it seems awfully hot. Luckily I use Amsoil. I’m going to fashion some wind deflectors for the rear cylinder.
468 is pretty small for a 131 man. 327 head temp (measured at the base of the plug) isnt too bad really. 33MPG is relative to how you ride it. If you regularly roll at 75 to 80mph, it will get much worse fuel mileage than averaging 65. advanced Ign timing will heat one up as well.
Woww!!! Such an awesome awesome explanation Kevin! I don’t find anyone on the UA-cam explaining things so clearly as you do. I just subscribed to your channel. Count me as a loyal follower! I just wish you had included the SE447 cam as well. A lot of people whose bikes are still under warranty are forced to go with it to avoid losing warranty!! I had to use the SE447 in my 2018 FLHTK due to this very reason. Keep more videos coming in. Cheers!👍
thank you very much. i didnt include that cam because it really doesnt compete that well. with the warranty issue....it has to be an epa friendly cam to work with the epa compliant street tuner...again for warranty. its a forced product and situation. so to compare it to others in the aftermarket, not really a comparison. I always like hearing suggestions on videos though...thank you for the comment and sub.
If you're worried about your warranty no point in worrying about how much "power" it's going to make because your feelings are always going to be hurt when comparing them to a nice aftermarket cam reason I passed on the warranty most of the problems with the bikes are from HD parts 😎
@@Tberg725 Agree!! I am in a position to go with an after market cam and dump the warranty.... provided there is a considerable difference in the numbers 😎
I put a 465 in my m8 and I like it. It runs really well going down the road and the acceleration feels really strong…. The idle rhythm has taken a lot for me to get used too though.
Mr. Baxter, that was a excellent description , very, very informative, I certainly appreciate your time, and effort, thank you very much, with all do respect, I’ll refer to you as “ professor Baxter But seriously, that was extremely helpful 🙏🙏
I had the zippers cam in my 2019 cvo. I wasn’t impressed. I’ve heard this from someone else recently too. So on my new 2020 road glide I’m going w the S&S cam w Khromewerks 2:2 pipe. Heard great things from this. Only if I could get the JD cycle works to tune it!! He’s had amazing tunes w this set up
You must’ve watched cycle fanatix and John. He had his bike done at JD Cycles. Dave the owner and tuner is a great guy and one of the best tuners on the east coast fact!!!
I love this video! I’m using it to try to learn which cam I want for my 107 m8 (solftail standard) I’m torn between the andrews m464 and the woods wm8-22xe
Many thanks Kevin for this awesome Video! I will pursue the RS468 thanks to you! Another note. The only reason i switched out my stock chrome Exhaust pipe on my Sport Glide 2020 to V&H Pro Pipe in black is eliminating chrome. I believe Chrome belongs in the Bathroom xD. But hell, I didn't know that stock exhaust systems can actually perform equally as good as a "competition or whatever" aftermarket pipes. All those who wish to maintain lower emissions and decent sound to make the bike pass in the yearly inspections is very convenient too. Win-Win!
@@KevinBaxter I wish I lived in your area. Unfortunately, my location is across the Atlantic. But I will spread your words and follow/join! While you´re at it. I have a specific question regarding the RS468 and the SE447 Cam. Which one will yield best low torque given the numbers without increasing fuel consumption? If any? is the lower duration and a little higher lift of the RS468 the winner in that case? I have the Sport glide 2020, stage 1 with Diag4bike tuner (usb dongle, presets maps) and SE heavy breather cleaner and a V&H Pro-pipe with quiet baffle installed. Not sure if you can point me into any of these cams directions. Perhaps the Knight prawler 22x cam (very weird numbers on that cam) if its any easier, you can write me on messenger or email. Christian.ademius@gmail.com I´ll pay as a token of my gratitude for any help through text!
Don Performance in Germany also advised that M8s like to have a CAT for performance gains.Im thinking about camming ny new RKS but keeping the stock header and hust using my KW 4.5inch slip ons.Is there a need to change the oil pump and cam plate?(inner cam bearing,lifters and pushrods will be changed).
The higher the centerline number the wider the RPM range the lower the number the narrower the RPM range is. In cars a 114 CL is good for a long range of RPM. A 106 can is good for a sort track type car because it runs in a narrower RPM range.
I was just up there. Give Rob a call at Robs Dyno Service in Gardner, Mass. Great fella. Great work. Tell him i sent ya. He can handle pretty much anything you'd need.
Which of the Three Cams would offer Best Reliability or Be the Easiest on the Bike / lifters etc ,Would it be the Fueling ? I'm happy Enough with Power But Would Ultimately Love to Retain Best Reliability, would Going with an SE torque cam be the Answer or Leave it As is.
I have a 114 M8 with 475 SnS cam. No extra intake nor exhaust. 108 hp and 124 ft/lb torque....with better intake and Freedom Max Radius we may get up to 120 hp. I happy with that...
Great info, been watching your videos on the M8s for months. Have you done any testing with the Woods 22XE. Can't find those numbers (lift, int close, duration, centerline, overlap) for this cam anywhere.
I have the Woods WMB- 22X cam in my 2019 Road Glide Ultra, Fuel Moto, RTX two into one exhaust, dyno tuned Power Vision, Harley Ventilator Extreme air filter. What cam would you recommend?
hard to say...id have to know more about you, where you ride, riding style, etc before i could recommend one. Be sure to check out my video on "how to choose the perfect cam"....that may help you.
Awesome informative video as always :) thank you. Understanding cams a lot more now after that. I don't see/hear anything about Zipper here in Australia. Looks like a good cam with a lot of power 👍
@@KevinBaxter So If I have an S&S Oil Pump and Cam Support Plate Kit installed, can the 468 cam just bolt into that? Let me know how much they would be shipped or I can email you?
Yes they can sir. Sorry...just saw this message. If you dont mind, call the shop. Jennifer can get you a quote with shipping cost, your address, etc. 678-226-9651. Thank you.
Thank you mr Baxter, that was a excellent tutorial , I followed right along 👍👍I too, believe the zippers would suit my desired performance goals, again, outstanding, I’ll keep an eye out for more of your videos.. excellent….
@@KevinBaxterKevin! any idea of when? I am about to choose a cam for my 107" FLSB . Looking for the best bottom flat torque cam, best efficiency and hopefully at no expense of fuel consumption and no increased emissions. Is the woods 22x the cam for me?
First let me start off I am hardcore Harley-Davidson van but always make me wonder when people spend 30000 or more on motorcycle and then first thing they have to do is to upgrade it to make a run with even I Goldwing??
Awsome stuff if I have a 95 inch on a 99 twin cam ., she really comes , salad after 4 grand .2@1 pro pipe . But. Yet rolls great on low end . , cam you say what # cam ? Erd head , helps?
Around 3:30, I think you misspoke, as we know (and you had even just said) , intake closing builds cylinder pressure and hence torque, but you said with the s&s having the earliest intake closing will have the lowest torque. Seems the opposite. You paused and it seems like you might have just got things backwards in what you said versus what you were thinking. Anyway, I like the videos and only wanted to point that out because it was confusing and I replayed it several times to make sure I didn’t hear you wrong.
Outstanding explaination. Very informative. Thanks!! I have a 2017 Road Glide Special with a 107. I am making my final decision on whether to purchase TMan's 128 big bore kit with HPI throttle body and intake 62mm, along with probably roller rockers. Deciding on which oil pump/camplate to use...either Fueling or S&S?? I want the torque to jump right in around 25k and have a nice bell curve without any loss's thru 4.5 to 5k. If you would sir, what can do you suggest along with a header pipe and muffler? I'd like to see a stout 145 or 150 torque and HP. Thanks!
If you've already chosen someone for your build, my best advice, would be to speak with your builder. If I was your builder, I would suggest watching both videos we did on cam plates...we did one for S&S and Fueling. I outlined all the features and benefits of each. Then, you can weigh which are most important to you and we would discuss.
Never understood why you'd buy a $20,000.00 dollar bike and immediately spend another $4000.00 to supposedly provide more performance. There is not a metric bike out there that would require such mods.
I'm subscribed to your channel from Japan. Thank you for all the awesome videos! BTW, what is your view of Screamin' Eagle cams? Are they too conservative for EPA regulation reason? Thank you in advance.
yes. i agree with that statement. Japan...wonderful country. Spent quite a bit of time in Tokyo and Shinjuku with my fried Zak from Sundance. Great guy and shop for sure. Thanks for watching.
@@KevinBaxter Thank you for the response, Kevin. You visited Tokyo! Zak's shop is one of the most successful shops. I was using his original front fork springs on my former Road King:-)
look for one with an earlier intake close, slightly shorter lift or duration on exhaust side. It's hard to say specifically with so many out there to choose from. Lets generalize and say keep it on the smaller side like a S&S 509, or one in the .500 lift range with say a 36 to 40 int close and 230 to 240 duration.
Great video, thank you. If the Zippers cam produced those numbers with a stock headpipe and slip ons then there seems to no point to buy a complete exhaust system. The only reason to buy a complete exhaust system would be for the sound. Am I missing something?
GREAT QUESTION!!!! Was hoping someone would ask this. The number are great but....heat can still be a concern. Cats can not be tuned to the same AFR that non cat can. Add more fuel in the tune, and the cat gets hotter. Yes this can be done, and make great numbers....same numbers can be had without the cat, a slightly richer tune, and less heat.
@@KevinBaxter Thanks for the quick reply. Great explanation. I have a 2017 RGS with stock headpipe and 4.5" rinehart slip-ons. I will likely get the zippers cam, air cleaner and a tune and then get a full exhaust system later. It should save me some money in the short but give me the performance I'm looking for.
Does this mean that the D&D Billed Cat exhaust is a bad purchase? I ride a 17 Road King Special, with a 107. I recently found a deal on the D&D exhaust. I was only planning on upgrading the air intake, exhaust, and tuner. Does the cam need to be replaced as well for best results?
You have many many choices there. Please watch the video on "how to choose the perfect cam". It may help you. If you like, you can email directly and i can get the right cam to you for your riding style.
Kevin Baxter thanks for your reply but keep in mind that the stage 2 is done under the warranty that’s why I was asking if the cams from Harley are made by the companies you used for your video.
There are VERY few companies that actually grind cams. Andrews, for example, grind for just about every independent you'll find out there. That being said, not all are of the same quality...heat treat, etc. Not sure who grinds HD cams now. Regardless, HD grinds have to be conservative and work well with the tuning system (HD Street Tuner) they offer and maintain EPA compliance. You'll leave some performance on the table going that route but you'll be able to maintain warranty. It's a choice.
I like a cam for torque. I went with Harley's screaming eagle torque cam as I was under warranty. it feels fine. would been nice to have had it as a comparison. also I wonder how the feel is when you upgrade. does it take a big difference to notice. just curious. so if you go up 5 can you really feel it. or is it over 10 maybe.
most people would never notice 5 ft lbs. many cant notice 10. hard to say. just about every cam out there in similar categories, will produce gains over an SE cam...they are very conservative and made to meet EPA regulations...so they can be tuned with an EPA compliant tuner eg Street Tuner.
@@KevinBaxter i agree. that is why when someone says they have just done a stage 1 and notice the difference I don't think so. I sure did not. not until I did the stage 2 and the S&S headers with a dyno did I notice the difference. thanks for the response.
My warranty for my 107 FXLR is almost over. Is adding a DND FatCat exhaust and Zipper cams or SNS plus a full air cleaner going to hurt my stock MC or make it better.
tuned properly, it will certainly make it better. cooler, more power, etc. Give us a call at the shop tomorrow and we can help you get everything sorted out and on the way. Thanks. 6782269651
I have installed a s&s 465g torque and want to know what it equivalent is in it he SE range as my Se pro street tuner doesn’t list my cam un surprisingly?
I would highly recommend watching my video on How To Choose the Perfect Cam. If anyone answers this question for you, without asking you a bunch of questions first, they are doing you a dis-service.
Man i'd be pissed if I bought an M8 107 and put a S&S Cam in it. I've got a TC103 with the SE pistons, SE heads, SE 234E cams and a D&D Fatcat 2 into 1 pipe and I'm doing 96 HP and 108 TQ. It's on a conservative tune with a Harley Race Tuner. I'm guessing if I put SE 100 HP injectors, the bigger throttle body and manifold and tuned it I'd probably be in the 105 HP and 120 TQ range. You've pretty much just inspired me to find a nice used 103 Electraglide for a touring bike. Really no reason to buy a M8.
@Howard S Yes. Every OEM of every vehicle tunes their machines to the lowest common denominator among their customers. Leave it stock and you will ride safe and reliably with optimal fuel efficiency for many miles, and preserve the resale value. Tune it and you will loose or risk reliability, safety, durability, fuel economy, or all four. Don't forget that Japan ate Harley's lunch on these traits for decades.
Thanks for all the knowledge fixing to go to the garage and put my compensator man of war in my 2009 Harley-Davidson night train thanks have a good day
One thing i didnt mention that I thought I had. Much of the extra power made by the S&S and Zippers cam could be due to another factor...to properly tune with a cat installed in the headpipe, the AFR should be a bit leaner than without to avoid overheating the cat. The leaner mixture could also have created an increase in the numbers. All this said...the manufacturers test their products and all we can assume is that they published the highest number they obtained in their testing with the stated equipment. Main point of the video is to illustrate again, how the cam specs effect the final performance and characteristic of the curves, and what each means. Hope you enjoyed it.

Iv heard some people say yes and others say no and wouldn’t run until around.630 lift.I appreciate your videos and have learned a lot from them
Thanks for all the knowledge fixing to go to the garage and put my compensator man of war in my 2009 Harley-Davidson night train thanks have a good day
For my riding style, 475C S&S....love the info...
Awesome video as usual. Thanks for putting out relevant, informative videos for us Harley owners.
Kevin U are incredible. U made it easy for me to understand these numbers. I almost wish u could’ve included the woods 22x. But thank u for all u do u are a godsend
Thank you for the kind words Chris. Much appreciated and glad you find value. There are more cams to compare and other factors to consider when choosing...such as wear and tear on the valve train. The numbers matter and with each, pros and cons. Stay tuned....
Sorry to bother u again but your parts guy never called If I could get ur number that would be great
Love your videos. Very informative. Your opinion on a low to mid range cam for my new 117 low rider st. Also, your opinion on using the stock cam plate, oil pump, lifters, and inner cam bearing. I will be using a fuel moto dyno jet tune. Thanks for you help, and keep those great videos coming. It’s very helpful to have someone in the know, offering opinions as compared to the usual tube video personnel.
I absolutely love the way the S&S 475C cam made my m8 ride/sound
Great information video. I’ve been Cam Hoppin’ on my 131 M-8. Had a Zippers 468 in it for awhile. I just put in T-Man TMP-2652. It seems to have more power but it’s a gas hog...even without getting on it my best mileage is 33MPG. Seems to run hot too. I installed a Dakota Digital Gauge set at the same time. I’m getting head temperatures as high as 327 degrees on the freeway. The plugs aren’t white so I’m not running lean. They seem to be right. I don’t know what it was before I had the temp gauge but it seems awfully hot. Luckily I use Amsoil. I’m going to fashion some wind deflectors for the rear cylinder.
468 is pretty small for a 131 man. 327 head temp (measured at the base of the plug) isnt too bad really. 33MPG is relative to how you ride it. If you regularly roll at 75 to 80mph, it will get much worse fuel mileage than averaging 65. advanced Ign timing will heat one up as well.
Woww!!! Such an awesome awesome explanation Kevin! I don’t find anyone on the UA-cam explaining things so clearly as you do. I just subscribed to your channel. Count me as a loyal follower! I just wish you had included the SE447 cam as well. A lot of people whose bikes are still under warranty are forced to go with it to avoid losing warranty!! I had to use the SE447 in my 2018 FLHTK due to this very reason. Keep more videos coming in. Cheers!👍
thank you very much. i didnt include that cam because it really doesnt compete that well. with the warranty issue....it has to be an epa friendly cam to work with the epa compliant street tuner...again for warranty. its a forced product and situation. so to compare it to others in the aftermarket, not really a comparison. I always like hearing suggestions on videos though...thank you for the comment and sub.
If you're worried about your warranty no point in worrying about how much "power" it's going to make because your feelings are always going to be hurt when comparing them to a nice aftermarket cam reason I passed on the warranty most of the problems with the bikes are from HD parts 😎
@@Tberg725 Agree!! I am in a position to go with an after market cam and dump the warranty.... provided there is a considerable difference in the numbers 😎
That was awesome 😎 better than most movies 🍿
I put a 465 in my m8 and I like it. It runs really well going down the road and the acceleration feels really strong…. The idle rhythm has taken a lot for me to get used too though.
That Idle chop is what you want. Old school
I installed the 465 also...I feel like it doesn't like the 1800 to 2000 rpm in 2nd gear? You notice anything similar?
What bike and exhaust?I have the 465 kit on the way for my 114 Fxfbs.Did the sound get that choppy HD sound with the 465?
Mr. Baxter, that was a excellent description , very, very informative, I certainly appreciate your time, and effort, thank you very much, with all do respect, I’ll refer to you as “ professor Baxter
But seriously, that was extremely helpful 🙏🙏
I had the zippers cam in my 2019 cvo. I wasn’t impressed. I’ve heard this from someone else recently too. So on my new 2020 road glide I’m going w the S&S cam w Khromewerks 2:2 pipe. Heard great things from this. Only if I could get the JD cycle works to tune it!! He’s had amazing tunes w this set up
You must’ve watched cycle fanatix and John. He had his bike done at JD Cycles. Dave the owner and tuner is a great guy and one of the best tuners on the east coast fact!!!
Mr Kevin Baxter, excellent job/great video. Always look forward to watching you’re very thorough and informative vids. Cheers🥃 from Canada. 🇨🇦
Cheers Darren! Thank you sir. Always enjoyed my visits to Canada.
I love this video! I’m using it to try to learn which cam I want for my 107 m8 (solftail standard) I’m torn between the andrews m464 and the woods wm8-22xe
Awesome Kev. Zippers it is!!
Well, when I get a few $$$
👍
Take care.
Right on. Thanks! Give us a call when youre ready.
Many thanks Kevin for this awesome Video! I will pursue the RS468 thanks to you!
Another note. The only reason i switched out my stock chrome Exhaust pipe on my Sport Glide 2020 to V&H Pro Pipe in black is eliminating chrome. I believe Chrome belongs in the Bathroom xD.
But hell, I didn't know that stock exhaust systems can actually perform equally as good as a "competition or whatever" aftermarket pipes. All those who wish to maintain lower emissions and decent sound to make the bike pass in the yearly inspections is very convenient too. Win-Win!
youre welcome. when you get ready to pull the trigger, give us a call. Thanks!
@@KevinBaxter I wish I lived in your area. Unfortunately, my location is across the Atlantic.
But I will spread your words and follow/join!
While you´re at it. I have a specific question regarding the RS468 and the SE447 Cam. Which one will yield best low torque given the numbers without increasing fuel consumption? If any? is the lower duration and a little higher lift of the RS468 the winner in that case? I have the Sport glide 2020, stage 1 with Diag4bike tuner (usb dongle, presets maps) and SE heavy breather cleaner and a V&H Pro-pipe with quiet baffle installed. Not sure if you can point me into any of these cams directions. Perhaps the Knight prawler 22x cam (very weird numbers on that cam)
if its any easier, you can write me on messenger or email.
Christian.ademius@gmail.com
I´ll pay as a token of my gratitude for any help through text!
Thanks Kevin great info looks like I'm going with the s&s for my bike along with all s&s components 👍
Not a bad choice at all. Thanks!
Don Performance in Germany also advised that M8s like to have a CAT for performance gains.Im thinking about camming ny new RKS but keeping the stock header and hust using my KW 4.5inch slip ons.Is there a need to change the oil pump and cam plate?(inner cam bearing,lifters and pushrods will be changed).
Dang! Is there a video like this, on twin cams? I understand the principal, just like the discussion with the HD Zar
He did one before this video. He even says so in the beginning.
The higher the centerline number the wider the RPM range the lower the number the narrower the RPM range is. In cars a 114 CL is good for a long range of RPM. A 106 can is good for a sort track type car because it runs in a narrower RPM range.
Great insight Kevin! Great explanation! When the time comes, I’ll go zippers and s&s cam plate and Oiler
Great choice bill...give me a call when you're ready. Options are aplenty. Lol. 6782269651
Kevin Baxter I wish I was in GA but I’m way up in Boston! I wish I knew guys around here with your knowledge and attention to detail.
I was just up there. Give Rob a call at Robs Dyno Service in Gardner, Mass. Great fella. Great work. Tell him i sent ya. He can handle pretty much anything you'd need.
Another great video Kevin, so much info for picking the right cam
Glad you enjoyed it. Thanks.
Which of the Three Cams would offer Best Reliability or Be the Easiest on the Bike / lifters etc ,Would it be the Fueling ? I'm happy Enough with Power But Would Ultimately Love to Retain Best Reliability, would Going with an SE torque cam be the Answer or Leave it As is.
Kevin I have a 2018 m8 I really want the zippers 468 do I need to do the cam chest and oil pump also .?
If its in your budget, I'd highly consider it. Give me a call at the shop tomorrow and I'd be happy to discuss and give you price options.
I love my 468, I run the D & D EXHAUST and my numbers are awesome love the way it sounds love the way it performs!
What about S&S 475 cam I know it may not be a good combination but I got a 2in2 Freedom performance I would like to have 475 in my 114 Breakout
Have a twin cam myself but great information.
Thank you sir. How the numbers work, apply to all engines with cams really. Glad you enjoyed it.
Kevin, I have a 114 heritage with 300 Eliminator slip Ons. Can I do a zippers 468 upgrade with this exhaust? I do not like noise
Nice video. Would like to see, 472 cams, zippers. Fueling
I have a 114 M8 with 475 SnS cam. No extra intake nor exhaust.
108 hp and 124 ft/lb torque....with better intake and Freedom Max Radius we may get up to 120 hp.
I happy with that...
Great info, been watching your videos on the M8s for months. Have you done any testing with the Woods 22XE. Can't find those numbers (lift, int close, duration, centerline, overlap) for this cam anywhere.
Excellent as usual! I love the way you present the facts. Keep up the good work.
thank you very much sir! I greatly appreciate it.
thank you for all your effort putting put this info out there.
Glad it was helpful! Youre welcome.
I have the Woods WMB- 22X cam in my 2019 Road Glide Ultra, Fuel Moto, RTX two into one exhaust, dyno tuned Power Vision, Harley Ventilator Extreme air filter. What cam would you recommend?
hard to say...id have to know more about you, where you ride, riding style, etc before i could recommend one. Be sure to check out my video on "how to choose the perfect cam"....that may help you.
Great video Kevin!
Just one question though; If you want to achieve the Gnarliest, nastiest idle sound, what camspecs achieve that?
Awesome informative video as always :) thank you. Understanding cams a lot more now after that. I don't see/hear anything about Zipper here in Australia. Looks like a good cam with a lot of power 👍
Thank you sir. I cam ship em to you. Great cams for sure.
@@KevinBaxter So If I have an S&S Oil Pump and Cam Support Plate Kit installed, can the 468 cam just bolt into that?
Let me know how much they would be shipped or I can email you?
Yes they can sir. Sorry...just saw this message. If you dont mind, call the shop. Jennifer can get you a quote with shipping cost, your address, etc. 678-226-9651. Thank you.
@@KevinBaxter Hey kevin are the harley dealers stocking the 468 cam here in australia and which tuner is recomended for it ??
Thank you mr Baxter, that was a excellent tutorial , I followed right along 👍👍I too, believe the zippers would suit my desired performance goals, again, outstanding, I’ll keep an eye out for more of your videos.. excellent….
Good video, very informative,is woods in the M8 game?
It is and will be part of a topic in an upcoming cam video.
@@KevinBaxterKevin! any idea of when? I am about to choose a cam for my 107" FLSB . Looking for the best bottom flat torque cam, best efficiency and hopefully at no expense of fuel consumption and no increased emissions. Is the woods 22x the cam for me?
First let me start off I am hardcore Harley-Davidson van but always make me wonder when people spend 30000 or more on motorcycle and then first thing they have to do is to upgrade it to make a run with even I Goldwing??
Great and indepth explaination kevin well done keep up the great work
Awsome stuff if I have a 95 inch on a 99 twin cam ., she really comes , salad after 4 grand .2@1 pro pipe . But. Yet rolls great on low end . , cam you say what # cam ? Erd head , helps?
Thanks for watching!
Around 3:30, I think you misspoke, as we know (and you had even just said) , intake closing builds cylinder pressure and hence torque, but you said with the s&s having the earliest intake closing will have the lowest torque. Seems the opposite. You paused and it seems like you might have just got things backwards in what you said versus what you were thinking. Anyway, I like the videos and only wanted to point that out because it was confusing and I replayed it several times to make sure I didn’t hear you wrong.
Thanks for the comment Robert. What i was saying was "lowest torque" as in "lowest rpm torque". left a word out. LOL.
Did you ever compare the aftermarket cams to the Screamin' Eagle cams?
This was three years ago but has anything changed lately.
Outstanding explaination. Very informative. Thanks!! I have a 2017 Road Glide Special with a 107. I am making my final decision on whether to purchase TMan's 128 big bore kit with HPI throttle body and intake 62mm, along with probably roller rockers. Deciding on which oil pump/camplate to use...either Fueling or S&S?? I want the torque to jump right in around 25k and have a nice bell curve without any loss's thru 4.5 to 5k. If you would sir, what can do you suggest along with a header pipe and muffler? I'd like to see a stout 145 or 150 torque and HP. Thanks!
If you've already chosen someone for your build, my best advice, would be to speak with your builder. If I was your builder, I would suggest watching both videos we did on cam plates...we did one for S&S and Fueling. I outlined all the features and benefits of each. Then, you can weigh which are most important to you and we would discuss.
I havent chosen a builder yet. Where are you located? Georgia? I live in Jacksonville Florida.
I will look for those videos and watch them tonight. Thank you.
Enjoyed this video
I love youuuuu kevinnnnn,now i know whos the best
Never understood why you'd buy a $20,000.00 dollar bike and immediately spend another $4000.00 to supposedly provide more performance. There is not a metric bike out there that would require such mods.
I did se torque cam I love it
Plenty of dollars going into metric bikes of all types....
I'm subscribed to your channel from Japan. Thank you for all the awesome videos! BTW, what is your view of Screamin' Eagle cams? Are they too conservative for EPA regulation reason? Thank you in advance.
yes. i agree with that statement. Japan...wonderful country. Spent quite a bit of time in Tokyo and Shinjuku with my fried Zak from Sundance. Great guy and shop for sure. Thanks for watching.
@@KevinBaxter Thank you for the response, Kevin. You visited Tokyo! Zak's shop is one of the most successful shops. I was using his original front fork springs on my former Road King:-)
Can you do a video on a cam selection for an exhaust that is form over funtion.... fishtails on a 108
as in best cam/exhaust combos?
@@KevinBaxter just best cam for a true dual fishtail. All i can fond.are with 2 into 1. I know that is best perfomance. But ugly as sin
look for one with an earlier intake close, slightly shorter lift or duration on exhaust side. It's hard to say specifically with so many out there to choose from. Lets generalize and say keep it on the smaller side like a S&S 509, or one in the .500 lift range with say a 36 to 40 int close and 230 to 240 duration.
Great video, thank you. If the Zippers cam produced those numbers with a stock headpipe and slip ons then there seems to no point to buy a complete exhaust system. The only reason to buy a complete exhaust system would be for the sound. Am I missing something?
GREAT QUESTION!!!! Was hoping someone would ask this. The number are great but....heat can still be a concern. Cats can not be tuned to the same AFR that non cat can. Add more fuel in the tune, and the cat gets hotter. Yes this can be done, and make great numbers....same numbers can be had without the cat, a slightly richer tune, and less heat.
@@KevinBaxter Thanks for the quick reply. Great explanation. I have a 2017 RGS with stock headpipe and 4.5" rinehart slip-ons. I will likely get the zippers cam, air cleaner and a tune and then get a full exhaust system later. It should save me some money in the short but give me the performance I'm looking for.
good plan sir. when you get ready to pull the trigger, let us know. Thank you.
There is a reason to ditch the factory system on a bagger for example more power to be had with the fullsac pipe 👍
I'm sure Fueling choose the best exhaust for their final results
Does this mean that the D&D Billed Cat exhaust is a bad purchase? I ride a 17 Road King Special, with a 107. I recently found a deal on the D&D exhaust. I was only planning on upgrading the air intake, exhaust, and tuner. Does the cam need to be replaced as well for best results?
no not at all. that is a great choice for the M8
@@KevinBaxter thank you. Do you recommend replacing the cam as well?
kevin which one is the best cam (117ci CVO RG) Please advice
its a longer answer than that. there is no best cam... give this a look and i'll make a suggestion protwin.com/camselector.aspx
When we choose the stage 2 for the 114, which cam is installed for more torque?
You have many many choices there. Please watch the video on "how to choose the perfect cam". It may help you. If you like, you can email directly and i can get the right cam to you for your riding style.
Kevin Baxter thanks for your reply but keep in mind that the stage 2 is done under the warranty that’s why I was asking if the cams from Harley are made by the companies you used for your video.
There are VERY few companies that actually grind cams. Andrews, for example, grind for just about every independent you'll find out there. That being said, not all are of the same quality...heat treat, etc. Not sure who grinds HD cams now. Regardless, HD grinds have to be conservative and work well with the tuning system (HD Street Tuner) they offer and maintain EPA compliance. You'll leave some performance on the table going that route but you'll be able to maintain warranty. It's a choice.
I have the 468 in my 17 cvo 114 sg with tmax. Picked up 20 hp/tq with stock header and TBR slip ons.
I like a cam for torque. I went with Harley's screaming eagle torque cam as I was under warranty. it feels fine. would been nice to have had it as a comparison. also I wonder how the feel is when you upgrade. does it take a big difference to notice. just curious. so if you go up 5 can you really feel it. or is it over 10 maybe.
most people would never notice 5 ft lbs. many cant notice 10. hard to say. just about every cam out there in similar categories, will produce gains over an SE cam...they are very conservative and made to meet EPA regulations...so they can be tuned with an EPA compliant tuner eg Street Tuner.
@@KevinBaxter i agree. that is why when someone says they have just done a stage 1 and notice the difference I don't think so. I sure did not. not until I did the stage 2 and the S&S headers with a dyno did I notice the difference. thanks for the response.
exactly. youre welcome.
My warranty for my 107 FXLR is almost over. Is adding a DND FatCat exhaust and Zipper cams or SNS plus a full air cleaner going to hurt my stock MC or make it better.
tuned properly, it will certainly make it better. cooler, more power, etc. Give us a call at the shop tomorrow and we can help you get everything sorted out and on the way. Thanks. 6782269651
Thanks again. Good video
Thank you Max! Appreciate you my friend.
I have installed a s&s 465g torque and want to know what it equivalent is in it he SE range as my Se pro street tuner doesn’t list my cam un surprisingly?
Post stage 1 that tuner is a paper weight. Going the same route. Find a shop, buy a license for $300 for a power vision tune.
Can anyone answer this: SE Stage 2 Torque cam or Feuling Reaper 465 for M8 FXFBS. PLEASE.
I would highly recommend watching my video on How To Choose the Perfect Cam. If anyone answers this question for you, without asking you a bunch of questions first, they are doing you a dis-service.
@@KevinBaxter thanks. I am looking for torque from lowest RPMS, solo ride, 2021 FXFBS - IF that helps.
@@KevinBaxter with badass lope 😜
@@KevinBaxter I realized now, that I watched your video twice already. And there's no answer to above question 🤭
Man i'd be pissed if I bought an M8 107 and put a S&S Cam in it. I've got a TC103 with the SE pistons, SE heads, SE 234E cams and a D&D Fatcat 2 into 1 pipe and I'm doing 96 HP and 108 TQ. It's on a conservative tune with a Harley Race Tuner. I'm guessing if I put SE 100 HP injectors, the bigger throttle body and manifold and tuned it I'd probably be in the 105 HP and 120 TQ range.
You've pretty much just inspired me to find a nice used 103 Electraglide for a touring bike. Really no reason to buy a M8.
This inspires you to pass on an m8? That dont make much sense the m8 with just a cam and tune makes more power than your built TC lol
@@Tberg725 I was going to say the same thing.
Awesome thanks for the information!
Badass. Great info
Appreciate it Isaac. Glad you enjoyed it
Pretty sure my brain just got smarter !
Very flat Dyno printout...must be different format to whats used in Aus.
still don't see the bat you keep referencing
Excellent really good cheers
Great video
Why don't these engines come with better cams from the factory?
EPA regulations and a bunch of other reasons...
@@KevinBaxter Makes perfect sense thanks for the reply. Love the vids, learn new things every time.
@Howard S
Yes. Every OEM of every vehicle tunes their machines to the lowest common denominator among their customers. Leave it stock and you will ride safe and reliably with optimal fuel efficiency for many miles, and preserve the resale value. Tune it and you will loose or risk reliability, safety, durability, fuel economy, or all four. Don't forget that Japan ate Harley's lunch on these traits for decades.
To meet EPA laws. None of these cams in this video are not
🥴wow
G
All the harley dealers around me say the stock lifters are fine to use with an S&S 475, whats your take on this?
Thanks for all the knowledge fixing to go to the garage and put my compensator man of war in my 2009 Harley-Davidson night train thanks have a good day
