Made my first PayPal donation to you today. I enjoy your videos a lot even though I ride a competing bike. I especially enjoy your videos from Mexico. Ride safe.
Scotty you’re pretty much spot on. I’ve tuned CV40’s for years. 48 pilot and a 185 main with the 1988 needle is usually the go to for a 80 cu inch. 3 turns out on the air screw will get ya close. Always replace the junk plastic inlet.
I know how it all works, but it's nice to hear about the Jet Sizes. Can't think of anywhere else I'd have found those. I'm an AMI Certified Harley Mechanic, Class of 1987. Have a good un'.
Come on let's help old Scotty out with a little donation any amount 5,10,20,50, whatever let's show this man some love for the work he does. I will and did.
I have two fuel injection bikes 2005 and 2020 but i really enjoyed this video because it was relaxing to listen and watch a little going down the road in my big rig with a load of motor oil from NorCal heading to Fontana I love the old videos in between your new ones 👍
Thanks for bringing this one back! This is the video that kicked it off for me. I stumbled upon this about three or four years ago when I was having CV tuning problems and have been watching your videos and following your journey ever since! Ride on Man! Be Safe!
Great video Scotty! First time I’ve had someone explain the basics of exactly how a carburetor works. I’ve worked on a lot of carburetors and changed lots of jets. I never really had full understanding exactly how all the parts interacted with each other until now. Thanks for passing on your knowledge!
The wealth of UA-cam is sharing this kind of experience. Been running carbs for 45 years. For pilot fine tune. After gentle cruising for 10 minutes at 55 the header pipes are stupid hot and the cam cover is hotter than a fresh made coffee it's maybe ⅒th turn too far in/lean from optimal, 2 up cruising at 70 if it's stupid hot the needle needs raising or changing. Decel popping with everything else just right is probably because the idle is too low. The butterfly closes and the vacuum pulls too hard on the idle circuit, just try raising the idle a bit at a time till it's minimal or zero over run popping, it'll save on brake wear to be able to adjust the bikes speed using just the throttle and gears. On my 3rd Harley since 1988. I had an '88 sportster 4 speed chain drive, a '95 FXDL Evo and now a '99 TC88 FXDL with fueling 525 and Vance and Hines straight shots. Using 99 fuel runs a 45 pilot at 2 ⅓ and idle at 1000. Do all my own work. You should be able to annoy a spit from cold or a backfire from high rev throttle off maybe but this is about real world drivable with perfect manners when driving miss daisy to spirited performance testing. We are lucky in the UK to have 99 fuel at not much more than E10, those days may be numbered.
This is a good video. I have a CV Performance Velocity needle in my carb. It's about the same price as the 88 Sportster needle, but it is machined to not need a shim. I run a 46 pilot and a 185 main with a CV Performance slide spring, which is a little quicker opening. This is on my 06 XL 1200. The 04-06 Sportsters came with Buel XB style heads and the W camshafts, so they are a little thirstier than the engines in the solid mount bikes from 03 and earlier. It wil haul ass but will still get 48 to 52 MPG, depending on if I am on the Interstate or a 55 to 60 mph road. I got rid of the sucky vacuum petcock and put a Pingle style petcock and a washable Russel stainless steel fuel filter, and have had very good service. These CV's are sort of picky about float levels, so do what Harley says do when setting the float level and you will be a happy camper. Piss on EFI !!
Hey Scotty great video I know it will help lots newbs for sure. I sent you a little something since it’s Christmas time and I enjoy your channel immensely. I learned to do these carbs a long time ago when I bought my 2004 sportster and have done all of my own work on this bike including a hammer 1275, cams, and everything in between. Only thing I have a shop do is change my tires. All of us on the XL Forum change out those crappy screws on the bowl and on the top to stainless allens. So much better. I know there’s probably not too many women subscribers on here who do their own wrenching but wanted to let you know there’s at least one. Merry Christmas 🎄 my friend. I’m so jealous about your Mexico winter adventures but look forward to those future videos. Btw, I watch Adam Sandoval too and he speaks highly of you. ✌️ and safe travels South! Xena from the XL Forum
Thanks so much Xena. Moneys been running down since they canceled my other channel. Ive not known many women who wrench on their own bikes (or men for that matter) but there has been a few. Once met a girl who lost me in the mechanical talk. Of course she was talking BMWs 😊
This is the exact setup I run on mine and I've never ridden an injected bike that runs better all around. The EV27 is the cam to run for touring also. Good explanation for those still running a CV.
You are so correct about these carbs just jet it and maybe shim the needle turn the screw 2 1/2 to 3 turns out from stop and go ride, 48 pilot, 180 main is just right, don’t drill the slide or cut the spring,just ride, great video, I’m a retired Harley mechanic and there’s information about what happens when you drill the slide and or cut the spring don’t do it,thanks for the video
Always awesome content from you Scotty. Thanks again for taking the time. I've followed you for a few years now and have used your vids many times to tune my EVO. And she runs sweet.
I solved one major problem today, (at least I think I did) which was an air leak at the carb to manifold joint. I used a quality automotive hose clamp and now I can tighten it by accessing it from the side opposite the carb, with a long 5/16" wrench. Made a big difference, but there's more. I believe I will re-jet. I have a 45 pilot and a 180 main on a 1200 Sportster. I removed the plug at the idle mixture screw and found out it was completely screwed in, nothing out at all, so I turned it out 2 turns. I'm thinking about a 48 or 50 pilot and a 185 or 190 main. Now for an update. I tried all sorts of jet combinations and the bike kept running progressively worse. Bad VOES. If you have a bad VOES switch, the bike can run like crap and nothing you do will fix the problem except a new VOES switch.
i haven't had a carb bike in 20 years, but thanks for the trip down memory lane. I messed with every carburetor on every bike before that. when you bought thoughs early ss super es or gs if you had that big of a boar once you started.....jets for all season and elevations.
Just picked up a used 96 Road King with only 17,000 miles. This is one of the best videos I've seen to make this (New to me) bike run like a top as it's been sitting with bad gas for a year and a half. Wish I could have donated more brother. Thanks.
Excellent class, dude !! I don't use those CV carbs, but many moons ago, it was the bendix. My present scoot is fuel injected due to curiosity. You just did a good job with educating some of the guys out here.
Hi,Scotty gave you a donation for the video how to tune your CV carb.Bought a 1995 Road King for cheap and i am fixing it. Ride on American - Hungarian bro. Cheers from Canada.
I think, at least for the Electra Glide Classic, the CV carb was introduced in 1989. I have a 1988 but I have the receipts for an upgrade to a CV. When I took it from Wisconsin to Sea level Texas I did need to rejet it. Easy to rejet. Don't even need to take the carb off the bike, just drop the float bowl.
That thing is running beautiful! I'm sure you have tried one already but my favorite touring cam so far is the ev13. Happy trails in mexico! May be seeing you on the road next year
Just watched your video on cv carb tuning very nice I learned about that 88 needle gonna do that on my 2003 fatboy a 46 slow jet I already have a 180 main and 2 1/2 out mixture screw thanks mine runs good been tweaking it a bit but maybe this will make it run better I do have a little decel pop is why gonna change slow as per your advice thanks again and 👍
Good vidio Scotty I have a 88 softail custom I bought new in 88 love it ! Sometimes I pull thr carb apart to clean, it’s not a constant velocity though,but enjoy working on it !
I've been searching high and low for an explanation of why my bike runs the way it does and so far this video has shed a little light on it. I have an 03 ultra classic and it does the normal cough and spit when cold,but the longer i ride and the more it heat soaks the higher it idles. Sometimes it diesels when i shut it off. I bought it running this way. It has a k&n filter and kerker slip ons. Any help would be greatly appreciated.
I have the CV carb on my '89 Sportster. I modified back in 1990. Still a fine carburetor. I did that brass fuel inlet also. That plastic one broke and actually started a fire.
one of the first things I did on my Evo was replace the plastic one with brass ,just looked at it and thought ,'' An accident waiting to happen'' ,HD shame on you
@@ClovisPoint Yeah, A very small crack in that plastic fitting can turn into a big crack and leak very fast. My bike is an '89 . So it was good for over 25 years, but all these Evos are old now, so I'd definitely put the brass fitting in. On a brand new carb, I'd just leave the plastic one in.
@@syyenergy7 I'd still replace it with a brass one [peace of mind], thing about plastic, its inevitable one day its going to crack or break ,like plastic on rifles [especially European ones ,just nuts !]
Love the new carb video! Much more detailed than the other one. Unfortunately I have to let my bike sit sometimes and my freaking tiny hole for the accelerator pump gets clogged. I guess you could call it the accelerator jet. Pain in the ass to get clear sometimes
Really good video Scotty My Harleys are injected but my wife’s 2001 Suzuki with 4 carburetors that sat for a couple years and now it’s missing on one cylinder. Any ideas for an easy fix? It ran good when I parked it?
Id try running c-foam or some other carb cleaner through it for a while. Her carbs, like pretty much all of em, probably have a screw on the bottom of the bowls that drains them when opened. Just crank em open when it sits and leave them that way till she rides ot again.
George Smith (S&S) was good at hopping up Harleys in the 50s but he needed a carb that would give his motors more gas. So he went to a farmer friend and they took an old tractor carb, which was upswep, and designed the same thing that would flow through. An accelerator pump was later added. Very simple. I once took a tour of the S&S plant in Wisconsin and learned that there.
@@scootertrampscotty Scotty, I live 45 minutes away and I grew up following George and a few other area racers. I have a L series S+S carb #314 without a accelerater pump on my 50 panhead and a S+S super B without a pump on my 93 inch shovel head and on my 95 road king I have over 200 k and it has S+S super E. When you want to rock and roll S+S is the way to go..... Stay safe out there my friend 🙏 NITRO BUMS RACING RKFD ILLINOIS
Hey Scotty. I just subscribed to your travels. I watched a few videos. You said that your eye's are going. I also watch a lot of different stuff. And this lady say's to put a drop of castor oil on your eye lids at night before bed. And lightly rub it in. Give it a try it might help Even investigate the healing power of it.
Now thats a new one on me. Lately ive been traveling with 2 guys younger than me, 59 and 60 (im 63), and it definatly seems im the youngest one here. Theyre showing me what not to do!
Hay Scotty got all my parts to do my CV for my 86 Softail. Question: I got the 88 Needle, should I still use the #4 washer with it, or just the needle? This is exactly what I am looking for in performance . Thanks Great video.
Makuni sponsored me one of those once but their tuning directions didnt work. I couldnt get it right till a friend with a speed shop told me what to do. Those carbs only run well a little on the lean side. He had me use a #20 pilot. Kept the main jet that came on it (i forget the number) but Dale had me drop the needle one notch. The idle screw controls air not gas. He had me turn it in till the motor started to slow then back it only till it it came to normal speed. As for the squrter, use the smallest one. Dales directions worked really well!
I’m running a 1200 sportster with the Arlen ness stage 1 air cleaner, thunderheader, screaming eagle ignition module and andrews n4 cams. Can you recommend jet sizes I should use?I have trouble with start up and I feel I’m not getting proper throttle to complement the components installed. Thanks for your time.
I dont know Sportsters. My bikes almost always end up with a #48 pilot, #180 main, and idle screw 2 and 1/2 turns out. The slide, spring, and everything else stays bone stock.
Hello Scotty need your advice I changed my camshaft on my evo big twin FLSTN 1993 from Stock to Andrew’s ev13 I replaced intake manifold seals and they are tested and good. My problem is the following, I have a slow jet of 40 but looks bigger than a 42 which is the one I normally use “I live at 2.600 meters above sea” I adjust the mixture screw counter clockwise 1 1/2 turns but the rpm goes down a little “not optimal mixture? “ I close the screw all the way and the idle speeds up “better mixture?” but here is the catch the throttle response sucks bike spits up and tries to die when applying throttle, when I unscrew and put 1 and 3/4 turns the idle goes a little down but the throttle response is way better can you tell me why is this ? Do I need bigger or smaller jet ? Is it because the size 40 jet perhaps is faulty fuel hole bigger than it should compared to the side holes ?
Dont know how high 2600 meeters is because i think in terms of feet. But that motor generally comes from the factory with a #42 pilot, #160 main, and the screw 1/2 turns out. Your problem really sounds like the pilot jet. Next up from 42 is a 45, then 46 and 48 - which is what mine always end up with.
Stock 96 evo, what would be a good model number? I'm interested in function over form, less maintenance, better gas mileage etc. Looking for a good model number and jet size for best mileage and longevity.
That bike comes with a #42 pilot, #160 main, and the idle screw 1/2 turns out. Probably the best milage youre gonna get. But for smog reasons they all came a bit lean from the factory. If it runs fine id leave it alone. But if its to hot, takes for ever to warm up or coughs a lot on warm up id probably turn the idle screw to 1 and 1/2 or 2 turns out, go with a #45 pilot, which is the next size up, and maybe a #175 main. If u have an aftermarket air filter, pipes, and a cam they generally get a #48 pilot, #180 main, and idle screw at 2 and 1/2 turns (mine always do). Less if u live in the altitude.
I personally have never had one rip but u should be able to see a whole in it. U can also run it, rev the motor up and down, and watch if the slide seems to be moving smoothly.
Have a question Scotty or anyone on here has anyone had the transmission shifter linkage problem you have to take the whole primary part to put that think on or is there an easier way if so let me no
Ive had this same problem MANY times. On the older bikes yes, outer and inner primary. Newer bikes no. The thing will only break again though. Its only pot-metal. I always install an aftermarket steel shift arm, red locktight, then tack wield the arm to the shaft. Its not an integral/important shaft to the transmission. This is the only way ive found to keep it from happening again.

Scotty you’re pretty much spot on. I’ve tuned CV40’s for years. 48 pilot and a 185 main with the 1988 needle is usually the go to for a 80 cu inch. 3 turns out on the air screw will get ya close. Always replace the junk plastic inlet.

Great video Scotty! First time I’ve had someone explain the basics of exactly how a carburetor works. I’ve worked on a lot of carburetors and changed lots of jets. I never really had full understanding exactly how all the parts interacted with each other until now. Thanks for passing on your knowledge!
great tip on the gas leaking out the out the over flow saved me thanx Scotty
The wealth of UA-cam is sharing this kind of experience.
Been running carbs for 45 years.
For pilot fine tune.
After gentle cruising for 10 minutes at 55 the header pipes are stupid hot and the cam cover is hotter than a fresh made coffee it's maybe ⅒th turn too far in/lean from optimal, 2 up cruising at 70 if it's stupid hot the needle needs raising or changing. Decel popping with everything else just right is probably because the idle is too low. The butterfly closes and the vacuum pulls too hard on the idle circuit, just try raising the idle a bit at a time till it's minimal or zero over run popping, it'll save on brake wear to be able to adjust the bikes speed using just the throttle and gears. On my 3rd Harley since 1988. I had an '88 sportster 4 speed chain drive, a '95 FXDL Evo and now a '99 TC88 FXDL with fueling 525 and Vance and Hines straight shots. Using 99 fuel runs a 45 pilot at 2 ⅓ and idle at 1000. Do all my own work. You should be able to annoy a spit from cold or a backfire from high rev throttle off maybe but this is about real world drivable with perfect manners when driving miss daisy to spirited performance testing. We are lucky in the UK to have 99 fuel at not much more than E10, those days may be numbered.
Best carbonator video I've ever watched
This is a good video. I have a CV Performance Velocity needle in my carb. It's about the same price as the 88 Sportster needle, but it is machined to not need a shim.

The 04-06 Sportsters came with Buel XB style heads and the W camshafts, so they are a little thirstier than the engines in the solid mount bikes from 03 and earlier. It wil haul ass but will still get 48 to 52 MPG, depending on if I am on the Interstate or a 55 to 60 mph road. I got rid of the sucky vacuum petcock and put a Pingle style petcock and a washable Russel stainless steel fuel filter, and have had very good service. These CV's are sort of picky about float levels, so do what Harley says do when setting the float level and you will be a happy camper. Piss on EFI !!

Bikes are all a little different so i dont know what yours wants. Ive just got a stock needle. It works good enough so i aint changing it 😊
Great video Scotty, I put a Mikuni HSR42 on my Twin Cam 88, what do you recommend for the pilot jet size and main jet size?
Makuni sponsored me one of those once but their tuning directions didnt work. I couldnt get it right till a friend with a speed shop told me what to do. Those carbs only run well a little on the lean side. He had me use a #20 pilot. Kept the main jet that came on it (i forget the number) but Dale had me drop the needle one notch. The idle screw controls air not gas. He had me turn it in till the motor started to slow then back it only till it it came to normal speed. As for the squrter, use the smallest one. Dales directions worked really well!

I wonder how Al Gore adjust his Harley carburetors
Show more Mexico
Im there now
I’m running a 1200 sportster with the Arlen ness stage 1 air cleaner, thunderheader, screaming eagle ignition module and andrews n4 cams. Can you recommend jet sizes I should use?I have trouble with start up and I feel I’m not getting proper throttle to complement the components installed. Thanks for your time.
I dont know Sportsters. My bikes almost always end up with a #48 pilot, #180 main, and idle screw 2 and 1/2 turns out. The slide, spring, and everything else stays bone stock.
Hello Scotty need your advice I changed my camshaft on my evo big twin FLSTN 1993 from Stock to Andrew’s ev13 I replaced intake manifold seals and they are tested and good. My problem is the following, I have a slow jet of 40 but looks bigger than a 42 which is the one I normally use “I live at 2.600 meters above sea” I adjust the mixture screw counter clockwise 1 1/2 turns but the rpm goes down a little “not optimal mixture? “ I close the screw all the way and the idle speeds up “better mixture?” but here is the catch the throttle response sucks bike spits up and tries to die when applying throttle, when I unscrew and put 1 and 3/4 turns the idle goes a little down but the throttle response is way better can you tell me why is this ? Do I need bigger or smaller jet ? Is it because the size 40 jet perhaps is faulty fuel hole bigger than it should compared to the side holes ?
Dont know how high 2600 meeters is because i think in terms of feet. But that motor generally comes from the factory with a #42 pilot, #160 main, and the screw 1/2 turns out. Your problem really sounds like the pilot jet. Next up from 42 is a 45, then 46 and 48 - which is what mine always end up with.
Hey Brother, good to see you back
99 dyna. How bout if the plug are black and sooty?
Leaner?
Stock 96 evo, what would be a good model number? I'm interested in function over form, less maintenance, better gas mileage etc. Looking for a good model number and jet size for best mileage and longevity.
That bike comes with a #42 pilot, #160 main, and the idle screw 1/2 turns out. Probably the best milage youre gonna get. But for smog reasons they all came a bit lean from the factory. If it runs fine id leave it alone. But if its to hot, takes for ever to warm up or coughs a lot on warm up id probably turn the idle screw to 1 and 1/2 or 2 turns out, go with a #45 pilot, which is the next size up, and maybe a #175 main. If u have an aftermarket air filter, pipes, and a cam they generally get a #48 pilot, #180 main, and idle screw at 2 and 1/2 turns (mine always do). Less if u live in the altitude.
How do you tell if your
diaphragm in the carburetor is good or bad????? I really need help on this . Thanks for any help!!!!
I personally have never had one rip but u should be able to see a whole in it. U can also run it, rev the motor up and down, and watch if the slide seems to be moving smoothly.
Have a question Scotty or anyone on here has anyone had the transmission shifter linkage problem you have to take the whole primary part to put that think on or is there an easier way if so let me no
Ive had this same problem MANY times. On the older bikes yes, outer and inner primary. Newer bikes no. The thing will only break again though. Its only pot-metal. I always install an aftermarket steel shift arm, red locktight, then tack wield the arm to the shaft. Its not an integral/important shaft to the transmission. This is the only way ive found to keep it from happening again.
@@scootertrampscotty thanks Scotty keep the videos up my man love your channel
eye wanna put a cv 0n my ir0nhead. b0t a 22mm intake f0r a sn0wm0bile t0 use but still needa cv carb.
🤘😏🤘
Lotsa shops still have a box full of CVs but theyre mostly in parts so u gotta build one.
@@scootertrampscotty ill keep l00kn.
😉👌
GOOD TIPS
