CVK40 Carb part NEEDED!!!

Hey all...I've been trying to diagnose a fuel delivery issue with my 1996 KLX650C (no mods) recently after it had been sitting a long time. Prior to me, my Uncle had cleaned the carb and then it sat. I tore carb apart to find the dang jet-needle (collar) is missing! Can't find this part ANYWHERE online so far. Dealer can't get it anymore as it's discontinued. I really don't want to spend a couple hundred dollars on another used carb just for a $30 part. I also tried the one for a Harley CV40...it doesn't work (someone on another board said it does...not even close).

Anybody got one laying around or an old carb they'd part with?

Could I possibly get one machined if I could get the specs?

Thanks in advance!

Might try the Keihin USA distributor . . .

What carb model does the KLX use? Just wonderin'!

If a CVK40, looks like the needle jets would be all same-o; my perspective only.

Thanks, I have sent an email to the folks at Sudco (they are the main importer of Keihin Carbs for U.S.) and am waiting to hear back.

The carb model is the CVK40. But the part has been discontinued (according to Kawasaki anyway). And the same part off the CV40 that Harley used does not fit.

I'm stuck and might have to purchase a complete carb at this point simply to get one small piece that should be ridiculously easy to manufacture (it's basically a little coupler that the needle sits in from one end, has a lip around the middle to keep from falling into the venturi, and then is held in place by the main emulsifier tube on the other end).

Here's a reference for the part from BikeBandit for a 2007 CVK40:

16017:, JET-NEEDLE,#6, 16017-0055 (Fiche reference #, Description, Factory part number).

If you can find a KLX650 fiche, you can research the part there (BikeBandit.com). Kawasaki, "View Parts Diagrams" may produce similar results.

EDIT: Uh-oh; found the KLX650, but . . . with HEARTBREAKING words:

If we're talking about the same part; it's 16017-1367 for a '96 KLX650C......a '96 KLR shows a 16017-1254 superceded to a 16017-0055. I have no idea what the differences are.

Yeah, thanks...I was gonna say mine is part# 16017-1367... Actually, looks like someone found a rebuild kit for the KLR that contains that piece so I might be in business!!! Thanks for the help!

I wonder if the difference has to do with the size of the needle that sits in it?

The more I fiddle with these things the more strange stuff I run into.

The difference in the various collars, at least within the Kawasaki line, seems to be the length from the shoulder of the annular ring to the end of the section that sticks up into the venturi. For example, the KLR collar is about .020" longer than the Vulcan collar.

MTurner00 has definitively determined that the Sportster collar has larger outside diameters than the Kawasaki collars and won't even enter the emulsifier/jet holder chamber.

The Kawasaki bore through to the venturi is .200", with the small end of the collars being .196" and the large end being .205".

The OEM KLX650 service manual does not even state what Keihin Needle Jet # / size is used. It simply gives the 16017-1367 part number! Used in both the -A dirt model & -C dual sport model.

I can also only suggest one try the KLR650 #6 / 16017-0055 needle Jet. It will either be richer or leaner, I would guess.
Maybe one ought to also order the KLX650-A adjustable jet Needle, circlip & thick brass top spacer, works well on the KLR650s, correct?
