The Anatomy of a Harley Davidson CV Carb : Pro Tip

The CV carb has long been a staple of the Harley Davidson that is often overlooked for "better" aftermarket options. The reality is that the CV or constant velocity carburetor is a very capable carb, especially with a little modification. We show you the basics of the CV carb and point out it's strengths and weaknesses.

IMO THE absolute best carburetor ever made. 100, 000 plus miles on my FLHTC and several Sportsters and a Super Glide

Excellent video by a competent technician who spoke clearly . Well done to the filming man too . It may have been worth mentioning the emulsion tube as the reason for my '96 Wideglides poor running was the tubes tiny holes were blocked due to the Bike sitting for over a year . Dried un-leaded petrol to blame . Thanks for posting ! .

Excellent video, brother. Very informative and exactly what I was looking for. Thanks so much for taking the time.

Great video! Nice to see how the parts actually move with respect to each other, and it's pretty clear where you need good o-rings for proper operation. Thanks!

Great video. Thank you! We need more carb videos online.

I have a cv on my 2001 Buell M2 cyclone. I love it . But from the Buell factory mine came with a idle adjustment cable that works excellent. I'm not sure what part number they used but I recommend everyone get that part. It makes adjustments easy because you can just grab the knob that hangs out just above the top cap on the carb. And just below the gas tank . IT IS SWEET!!! And as for there not quick too respond!! That's bullshit! I have 2 on my Buell and my FXR AND THEY RESPOND LIKE LIGHTNING !! ITS ALL IN HOW YOU SET THEM UP!! MY BIKES ARE SUPER FAST OUT OF THE HOLE AND ALL THE WAY THRU THE GEARS. NO HESITATION EVER!! MY SETUP IS MY OWN SECRET! YOU HAVE KNOW THAT CARB INSIDE AND OUT!

On these accelerator pumps, there should be NO gas in the top side where the rod is...If there is gas, there is a no seal condition or breaks in the diaphragm which will cause a puddle of oily cooked gas on the crankcase right up under the carb ...It took me a year to figure that one out.. I was thinking I was getting crankcase breather oil mist blow by the whole time. It ended up being a bad diaphragm in my accelerator pump causing the stain on my crankcase which I can't remove n

Awsome video I cant wait to get my 88 sportser project going

Since it’s a Japanese carb, they use JIS Bolts. They usually strip when people use a Phillips Screwdriver instead of a JIS Screwdriver… from what I personally learned in the past… multiple times

What is the brass plug right next to the mixture plug? The carb bowl wraps around it. I accidently drilled this one out when i was looking for my mixture screw.

I have a Vulcan 750. It cost a lot to get running so I started working on it myself. Can’t afford the $175 hr mechanic. After having two carbs “broken” according to the mechanic I’ve started messing with it here and there. I found a cv40 conversion kit online from a German welder. It seems to be a good option for simplifying the carb a little and making the parts cheaper. My issue is I am more a small motor and two stroke mechanic than these carbs. So after getting it on I got it to crank and fire but it will only hit one cylinder and then wait for a full rotation before it will fire again. I’m at 500 elevation and was wondering if there are any tips for me to just get if firing so I can start adjusting from there. What size jet should I use? Ect. I’m going to be playing around with different adjustments next week and see how it tunes out.

Thanks for the breakdown video. ‘96 1200C needs enriched halfway out to run smooth but then when idle at a light or stop the idle is higher than it should be and I want to fix it. I’m guessing gas varnish so needs a good cleaning??? Don’t need high performance just smooth running and good low idle. Do you have the carb rebuild kit for it and what does it cost? I’m in Raleigh/Durham NC. Thanks again for the video.

Any idea on what my air flue screw should be turned out at in a 03 1200 with straight pipes and stock breather

[edwardfoehring]

I've got a 2003 sportster 1200 how do i know what overhaul kit to order

Upgrading my stock air element on an 06 FLSTF to a Vance & Hines VO2 Rouge. Already have Vance & Hines Longshots. Do I need to rejet my stock carb?
