Keihin/Sudco CVK-D36 Carburetor Rebuild Part Numbers

Postby Longhorn450 » Sun Aug 06, 2017 11:36 pm

I have gone through my carbs twice now after getting my bike in Feb and was just unsatisfied with the obscure nature of genuine Keihin replacement parts for these carbs. I knew they had to exist and that I was probably just not looking hard enough for them. Well, I found almost all of the important parts that need replacement with a typical carb cleaning/rebuild and thought they could be of some use to others. You no longer have to order semi-close fitting valve seat o-rings and air/fuel screw o-rings when rebuilding your carbs:

If you go to one of Keihin's websites and are looking for a diagram or parts list for a CVK carb, you won't find one. They do however list a series of carbs called FCR Street, which, for some reason, matches our carbs almost identically in terms of parts. Our carburetors are NOT FCR (stands for Flat-CR, idk what CR means) carbs. We have CVK-D, which are Constant Velocity carburetors ('D' denotes the use of a throttle position sensor). But the parts list and exploded diagrams are virtually identical, with a few changes.

FCR carbs use a mechanical linkage between the throttle on the handlebar and the carburetor slide (plastic piece that the diaphragm attaches to) to raise the slide and needle to allow more fuel flow when the throttle is opened. FCRs also use an accelerator pump for rapid throttle openings. These are supposed to provide better throttle response.

Constant Velocity carburetors use engine vacuum to raise the slide and needle to allow more fuel into the engine when the throttle is twisted. Our CVK-Ds also do not use an accelerator pump.

That is a very light overview of those two types of carbs and far more information is available on the google-machine if you're interested.

All of these parts are currently still available from at least one of three vendors:

https://jetsrus.com

http://www.sudco.com
catalog: http://www.sudco.com/catalog38.html#313/z
price list: http://www.sudco.com/images/Sudco%20Price%20List.pdf
***Part numbers use a '.' instead of a '-' in the price list.

http://www.power-barn.com

I have ordered from Mike at jetsrus.com a couple times recently and he gets you the right stuff quickly. I also ordered from Sudco this week for the first time and they got me my stuff within 3 or 4 days and I am on the opposite coast as they. Sudco is typically a wholesale vendor but they also allow retail orders via phone (if you do this, save yourself some heartache and have the part numbers ready when you call as they don't have a a make/model/year software implementation). I have never used power-barn but they seemed to have all of the parts too.
