- IMPORTANT MESSAGE END OF THE VIDEO YOU DON'T WANT TO MISS!
Just my own personal run through on how I rebuild a my KEIHIN CV Carburetor that's I use on my Harley Davidson Sportster Chopper. Although I do use a Keihin CV Carburetor for every Harley Davidson I own. I have a CV Carburetor for my Heritage Softail and Electraglide. But this time, it's fixing issues on the Keihn CV Carburetor that's on the Sportster Chopper.

The youngsters at my local Harley dealership should watch this. Watched a younger guy try and start a early 90s used bike. He didn't know what a choke was.
Give them a set of points and ask them to figure that out! Hahhaha
@@whatsstefon Took 10 minutes after trying to start the bike, an older customer walked up and pulled the choke out and said, now...
@@wcraiderevo8078 haha. I went to see a bike with a friend. He was looking at getting an older Harley. It was advertised as would not start or run.
The owner kept trying to. I noticed that the new unbranded carby was on upside down.
A part of me wanted to buy the bike. But all I could think of was “what else isn’t right in this bike?”
@@whatsstefon It is part of the reason why I pass on about 75% of the adds I see, of interest, on craigslist. People don't know what they have. It is either a scam or they have no clue how to take care of it. Most of the routine maintenance just takes a little time and willingness to get your hands dirty, case in point, the voltage regulator swap on my 97 Heritage, simple 15 minute job I crammed into an hour...took 45 minutes to find all of the correct tools, crimp, and electrical connector and those darn zip ties.
@@wcraiderevo8078 likewise here in Australia. In addition to that, the asking prices here are stupid.
There is a washer and o-ring in addition to the spring on the tip of the IMS screw.
Stoked for the garage coming soon.
Me too!
Don't forget to hit that thumbs-up over a hundred people watching... this guy has great information!
Thank man!
I have had good luck with the CV Carbs. Glad your getting the garage started!
this weekend I made a mount for my oil guage/mp3 player(old school) from aluminum. was using lacquer thinner and spray paint in the basement. my ole lady didn't complain at all..... true blessing. I usually spray outside but here in PA. the temperature was 20 degrees outside.
Porch seems like a good alternative to the living room for this rebuild. Startup with a rebuilt carb is always a good feeling. Hope to see that soon. I bet the Misses is about as happy about the new garage as you are. Thanks for sharing!
It looks like you might be missing a couple of parts on the CV. On the A/F idle screw there should be a washer and o-ring to seal that area on top of the spring. There's also a rubber boot that goes around the accelerator pump rod and connects to the carb to keep water and dirt out. If it was there I missed it when you put the bowl on. Congrats on the dirt pile!! Looking forward to more garage building content!
Awesome!....cant wait to see what it's gonna be like and what you do with it!....congrats brother!...honored to be a part of the journey
I know nothing about engines, but watching you in all of your videos makes me think I can do anything, I won't, but if I had to, I know that I could. . It is the way that you show us 💯
Thank you, Desiree.
Thanks for the CV Carb video. My 87 Low Rider has been "congested" for a while so I am going to order a rebuild kit and giver her a go. Congrats on getting the garage project started. I know you have to be looking forward to getting your scoots into a dry stable area. Keep the rubber side down and be safe out there.
Dad is gone now, he was a life long Harley rider and mechanic which he passed on to us. In 1972 he rebuilt a Honda in our living room because there was no garage in our Naval Housing Unit. I am pretty sure my parents relationship was a bit different after that bike rebuild! Good stuff Saddle Tramp! Subbed And Stay Well Man!
Man Tramp so rewarding/satisfying to see this done by a regular guy with regular tools👏👍🇺🇲
I like it simple
Really enjoy these Funk and jazz tracks in your videos LOL. Thanks for sitting down and taking the time to show us about carburetors. I learn something new every time I watch one of your videos. And about the garage. Don't stress. Stay positive, keep the faith and just let everything unfold. So cool you get to design your dream garage!
God bless you & the Missus ST !!!
I don't have a garage, I rebuilt my fatboy in the living room. The wife said it was her or the bike, I kinda miss her.
I rebuilt a Sportster in the kitchen (linoleum floor vs. carpet). Thought I was being considerate.
💪👍😎
I built a 70 Sportster and a pan/shovel/evo in my downstairs living room, on the laminate floor.....and she didn't mind!
Great tutorial for a rebuild. Hope they have been able to work on the garage and the mud didn't wash away with all the rain we have been getting.
Good to see some progress for you on the garage!!! Also that was a good job explaining the carb rebuild. People are lucky to have guys like you to help em out with this stuff. Keep on Bikin!
Thanks 👍
Should be a small O ring on the accelerator nozzle that seals against the carb body. Also should have been a small washer and O ring on the mixture screw.
Your right. I went back and replaced it. As far as the mixture screw... beats me, but there wasn't an o-ring and washer with it. I would've figured there'd be one, but it seems to run just fine without it.
Outstanding tutorial of detailed mechanical inclination by the Harley Houdini once again! Ladies and gentlemen this man is NO dummy as he himself says in the video 😎. Well done sir Tramp! Bravo 👏.
Thanks, bro. This one took forever to put together. Much appreciated as always.
So good. Hope everything goes good.
Great video and very helpful but these are Japanese carbs and while the screws may look like regular Phillips they're actually japan industry standard so to avoid chewing up the heads you really should use a J.I.S screwdriver-I know as I found out the hard way!
I Liked this video, learned alot. You made it easy to understand without over talking it. A lot of "how to" videos drone on and on and make me want to jam an ice pick in my temple. Nice work!
When I worked in a dealership many moons ago we had good results with cv carbs by using 48 pilot jets, 160 -180 main jets, drilling out the emulsion tube slightly, drilling out the return hole in the slide slightly, shorten the spring by 1 and a half and then stretching it back to the original length.
Best of luck with your new shed, man
Forgot to mention a thin washer under the needle also helps..
G;ad to know you are getting some progress on the garage! Wish I had your skills man!
The seal / gasket between the carb and manifold was kicking my ARSE as this was my first carb cleaning.... I liked and subscribed!!!
Hey, man! Thanks and welcome!
That can be a pain sometimes. The manifold to head seals are delightful to install and have no leaking.
Yey So happy for you. Glad everything is coming together.
Nice handful thanks for the info! I just purchased an 86 Softail Standard with 22000 original miles so I got a carburetor to clean up
Sounds great!
Nice video on cleaning and rebuilding the CV carb, anyone that watches this video should be able to do their own clean and rebuild, thanks.
Thanks 👍
Heck yes Dirt is the beginning! I loved this video because this is what you do so well with old school bikes. My Vulcan has a carburetor and drum brakes in the back.. It's not a Harley but it is old school. I was a cars and coffee today and I had a lot of questions about it. There was a bunch of antique Indians and Harley's there. Old bikes are becoming a thing and it's about time. Thanks for the lesson on carb re-builds.
Enjoyed that carb rebuild….Awesome, the long awaited garage build has begun!👏👍🙏
light at the end of the tunnel...a well deserved new garage , greetings from the UK.
Super easy done it quite a few times, I find it fun...
hope all is well, wishing the best of luck to your garage.
I liked the laid-back approach, and all of the basics you need to get by.
Getting too high tech can be intimidating for people.
If it's really crusty inside, soak it overnight in a mix of Cleaning Vinegar & water.
You don't need a laboratory, the back porch will do 👍
Thank you Saddletramp…Great carb video! I’m looking forward to seeing your new garage!
You and me both!
Hey bro, thank you for the video! I've watched more than a couple this morning and you are the only person to explain about the lip of the diaphragms fitting into the grooves when reassembling, and many of those videos where done by HD service techs! Again bro thanks for giving good information
Sure thing! Glad this helped.
Love how you disassembled/reassembled the carburetor and explained all the parts and how it works. I don’t have a carburetor but would definitely watch this over and over if I did. Great video as always. Take care brother 🤘🤙
Glad it was helpful!
Great job editing and explaining the process. You got a new sub, share, all alerts for that one guy.. Very useful. Be well.. ride often and safely
Hey thanks man!
New shop will be great, love it, have a blessed week my friend
Thank you! You too!
I'm about to rebuild the Bendix Zenith on my '72 FLH for the 3rd time in 30yrs.
If you don't have a gallon of carb soak solvent and an air compressor setup, you can use a can of carb cleaner and one of those cans of compressed air for cleaning computer keyboards.
Fuel injection can't even come close to producing the classic Harley idle that a carb can.
Good informative video, and I'll be happy to see you in a shop.
Truth!
great video, enjoyed the heck out of it....easy to tell how excited you are over them finally bringing stuff for the garage from the grin thats going ear to ear lol great video and thanks for the lesson!! now to learn how to tune one of those.....
Best thing I ever did was put a CV on my Shovel. Those tapered needle are the best, the newer style don't work as well. Nice rebuild video too! Don't think we've seen that smile for awhile...
That was a great video on the CV rebuild with good details . Glad to see the new shop building is now in progress.
Thanks for sharing your videos and ride safe my friend.
Great vid mate. Always heaps of fun dodging the weather😂😂 I was hoping you had a dual carb setup. I jz bought two new Kiehin cvks for my vtwin ( shameful jappa), however they’re joined together in such a way on the bike where one carb services each piston and are joined together with shafts passing thru from one side of one carb to the other, Any ideas where or who’s vid I could watch for a step by step? I’m also not sure if I’ll be needing any special tools to complete this job. I guess the automatic answer most folk would say is jz do the reverse of the strip down of the current two carbs…this would be a great option if I wasn’t certain they’ve been backyarded before sometime prior to the bike being mine. For example, the float bowl drain plugs were nearly tight like wheel nuts and…..they don’t even match🤔 You have a merch store man?
So I was! Gonna rebuild my cv carb at my comfortable well lighted kitchen table in my house. However my wife was at the table as I watched this video and heard you say you decided not to do that because of the gas smell filling the house and how you lady would trip. So mine started flipping out about it. Out on the hard concrete for me thanks lol
Luv it! I do the same on my 1990 883. WORKS every time. Yea man, the garage is coming. Happy for ya!
Nice video, I’m still running the original Tillotson carb on my 69 FLH and it is a challenge at times just for parts. The leather Excelerator pump doesn’t do well with gas additives like Sea Foam. It just warms my heart when doing a carb and find where someone used pliers to disassemble it. Carbs have become a lost art.
Kinda seems that way.
I love your videos brother they're awesome I got 79 Ironhead 51 sprocet 21 sprocket changing the back sprocket out to a 48 tooth because of the video I watched I'm doing this thank you hopefully it gives me some longer legs for my iron head
You'll see a difference for sure.
Very informative & detailed...A awesome video for the Do It Self person....Great Job ! Glad to see
your new garage is up & coming.
Thanks for the insight Tramp very informative have had to do it myself but for those who haven't very good info
Keep it between the mustard and mayo and rubber side down GBU later
I`m happy for you that your building will be going up soon.
Thank you, David.
Glad to see ya back, can’t wait till you get the shop videos and I’ll be in your neck of the woods in aug might run into you.
Just checking out some of your previous videos. 👍
I bought a set of gunsmithing screwdrivers. They are perfect for carb work! And not that expensive. You can find the exact size driver for all those little brass jets.
Its good to hear you are finally going to get a garage started
If U get trash in the jets or ideal port U can use a torch tip cleaner or microw drill bit that hand drill clogged holes in torch tips. They work well to get trash out.
Back in 1982 I had a 1976 XLCH ... Local bike speed shop worked the engine and turned it into a real fire breather... after getting the motor back I had it up and running... only problem was that garbage Kiehn carb. The bike would sputter around 2800 to 3200rpm.My man at the shop suggested I get a Bendix carb with an adjustable main jet.... After install the bike ran like drag bike... loud because I had str as ight thru drag pipes... it was bored 30 over and ran circles around the other fast bikes.... That bike started on the first kick around 500 times ...one weekend I pulled into our local bars summer picnic. 5 hrs when I'm ready to leave it wouldn't start because the points had closed..... ha ha... a quick fix on the spot and she fired on the 1st. Kick as usual. I swear by that brand of carb.. Be safe and well..
Richard S. .....
The older I get, the more I love carburetors.
Glad to see the new digs are getting started!
GOOD VID BUD...i should probably do a vid on this at some point and go into much farther detail on principal of operation and what really does what...someday...cheers...also be careful with carb clean and rubber part as it can cause them to swell and deform...
Awesome video for cleaning and rebuilding a CV Carburetor. Easy to follow. Personally I like my Mikuni VM38 on my Shovelhead.
Good choice
Great video on carb!!! Back in my day that’s all I knew!!
Good video!!!
Happy to hear your new garage is coming soon!!!!
At 18:47, that little thing is called a spring seat. The dirt is a start! Good luck on the garage build.
The ethanol in our fuel attracts moisture from the air which then separates out as water at the bottom of the tank - its a problem of ethanol that affects all motors including new ones !
Makes sense
Thanks Nice video (👍👍👍) I I need to do that to my 75 ironhead 1000 Sportster. Best wishes to your new garage can't wait 🇺🇲☮️✌️✝️👍👍👍
Thanks 👍
None of these videos on cv carbs show setting correct float level. I know how, but I'm sure many don't know how to make this important adjustment. He didn't show putting the washer and O ring on the idle mixture screw. Spring first then washer and finally O ring. Screw all the way in till it lightly reaches bottom then back out 1 1/2 turns. Final adjustment done on warmed up idling engine. Most likely will need backing out another full turn for best idle performance.
Excited for you they are about to start in the garage! This rain has been a real Turkey in Baton Rouge too!
Here to man
Good to see ya. Glad you got over your funk.
WE HAVE DIRT!!!!!! 👊😎
A great video, man! I really needed a refresher for the carb (my ‘03 needs it badly). And you’re not kidding with these random squalls down here. Happy 4th my bro.
So happy to hear there is good progress on the garage you seem excited so it must be moving along! So stoked for the endless chopper building content! Have a happy 4th of July Brother 🍻🇺🇲
That exact same round chrome air cleaner was on the Tillotson of my 1969 XLCH when I bought it back in August of 1970. *Congrats on dirt.
That woman leaving the store behind you is immortalized by the nasty sneer she made when she realized she was on camera LOLOL
great video, but I really hope that is NON CHLORINATED carb cleaner...I always use brake cleaner
Awesome video very, very helpful. I just have one question if your accelerator pump goes bad will it prevent the bike from starting ? I'm only asking because mine went bad and I replaced it and everything is fine now. But all the other videos I've seen say the pump is just to get you over the hump from idle. IDK
It should still start. Won't be any good for acceleration.
Very nice. Great carb rebuild video. Long time no see.
That was very interesting. Now if I ever have a bike without fuel injection I'll know how to tinker with the carb. Don't worry, before you know it you will be working in your new garage!
I hope so. Thanks Nick.
Nice rebuild video! Keep on Trampin'...
Thanks!
I love these carbs, I've used these on everything.
Just flew past Slidell on our way from NOLA to Birmingham. Multiple down pours over the last few days. If you were to get caught in any of them I can easily see how water got in your tank. Truthfully I'm just glad you didn't drown.... 😂🤣😂🤣😂🤣😂🤣
Yeah it's been pretty relentless here with the weather.
He look's like the Fizzle Bomber, but great video !!!
Well done sir, and happy for you and the new building! 👍
Got a 1995 heritage CV carb how many turn should I turn my air ideal screw bottom it out then how many turn out
... with most any carb...from gently bottomed out...
..turn it one and a half turns out...
..fire your engine...then adjust it in or out to find where it sounds and runs right ride it..keep an eye on your plugs..
What Steven said
OK, now I know where that spring came from that was left on my table.
Lol... Heck of a way to find out, huh?
must be pretty humid, how do you cope with hygroscopic properties of ethanol fuel, does it
go off' super quick?. Get an ultrasonic cleaner, wish I had one 8(
Feel a case of 'garage envy' coming on.
Great job SaddleTramp Barry from Windsor Ontario Canada
This was a great video and I feel if I had a carb I could rebuild it now. Thanks for sharing. And I can't wait to see them building your new garage. Ride Safe
Glad to help
That cv is a great carb. Hard to beat even for some mild performance
I hear ya, man. It rocks
Thanks again for another great video. Look forward to seeing the next video.
Mark from Maryland
How’s your garage plans going be lovely ro put your bikes undercover
Hot soapy water, Dawn dish washing detergent and a toothbrush works pretty good. Use the carb cleaner to spray through the ports. I also keep a gallon or carb cleaner, with a basket included, witch I pick up from NAPA. Not a sponsor. 😉 lol!
There's an idea. Thanks!
Hey Corey , them emulsion tubes can get fouled quite easily over time , the water entrainment probably helped lol. I think that air filter is a Drag Specialties product if memory serves me , same as what I had on my 1980 flh as a aftermarket add on . I suppose the tramp ran great after the cleaning ? I have to find the next video when time permits adios bro !
Great rebuild video ! Would like to see the video of your wife kickin your butt after spraying carb cleaner all over the front porch! Lol! Great job Tramp
Lol
Great vid brother, but I miss the Starsky & Hutch soundtrack...be safe...
Yayyy!! That’s great news on the garage. CV’s are a nice user friendly part to rebuild, well for people like us who work on their own scoot. I’m up in the White Mountains NH right now, North Conway to be exact and it has rained 3 days straight, hopefully it doesn’t happen to me and the Mikuni lol Honestly I can’t remember a July 4th weekend where the weather has been raining and 40’s, it’s usually always nice but that’s New England for ya. Glad you got the Tramp up and running Corey, or I’m assuming you did. Hope you and the Missus have a great 1776💥🇺🇸
I love all my Keihin CV (Constant Velocity) Carburettors, (fitted on all later model Honda Bikes) compared to the old slide carburettors!! The CV version compensates for changes in air pressure, altitude, etc. They also include a nice accelerator pump for rapid acceleration! when required! They are much more fun than the latest, fancy, snazzy, EFI (Electronic Fuel Injection) devices...I reckon! If you want to adjust for a very slow tick-over, (and starve the engine of oil...LOL...), you need a proper "carburettor"...trust me! Take care, all!....😊...😊...!
Hope to see how it runs when you use it on the bike now
first thing I do is remove the float bowl, if there is crud in the bowls, I remove all the jets and clean em, dont shove wires thru the jets, they are brass and soft, and dont use the dishwasher to clean parts ,unless you like sleeping on the couch.
The Keihn carbs were (are) definitely worthwhile. Jesus' angels all around Corey and his lady.
Nice job on carb and awesome news on shop its happening brother amen
How do you adjust the float level on it. Is it like a car ?
What he said.
