I did Google the part number, but the few sites I checked didn't have them. I will let you know what I find out with the 40 slide.

maybe these guys can help

CVK carb on the kawa vulcan is basically the same carb, I suspect many of the kelhin parts will work, diapgragms for sure

Picked up a new 40 slide yesterday, seems to match right up. I will do a couple final measurements, but I think I'm good to go. It will be in in a few hours, I will report back on how it works.
Again, thanks to everybody offering help and parts.

Hoss; Maybe this link will help.

Interesting. Can't replace just the diaphragm because my plastic mount is quite burnt and damaged.
The full slide that is listed is the right number, says it is a replacement for the slide I picked up, for the 40.
I think I've got it licked, let you know soon.

Success! The 40 slide works great, fit fine, ran really good. I forgot how quickly this thing comes up on the limiter.
Thanks everyone.

That's great !   I have to watch what you do here...My 01 will probably end up with a lot of similar repairs

Hogman, which model do you have? If it is an FLH, Touring model, keep an eye on the swingarm, they have a tendency to break at the pulley. In '02, this was redesigned.

2001 FLHT... Yep..You warned me about that a while ago when I was chasing a vibration.. I checked it real close last spring when I did the Swing arm isolator rubber mounts.. I'll be looking at it again soon.. New tire is here and that will be going on soon...

easy check on the slide. Blow shop air acrooss the large port on the inlet of the carb. if it raises all the way & holds chances are ur slide diaghram is good.

How many PSI ?   My compressor is at about 125 psi...Is that to much to blow in there to check slide operation?

I was thinking I'd check mine while the AF is off, just don't want to over do it and rip that diaphragm..

No

Just slowly squeeze theair nozzle across the eyebrow slide sshould raise & hold as it slides up,goes up & drops or can't hold a steddy height the diaphragm may be compromised.

The slide from a CV40 fit the CV44.  Did the diaphragm also fit?

Some posts mentioned eyebrow.  I thought this was some kind of typo.  But at the top of the carb is upside down smile about 1", or an eyebrow.  Watching videos, some have holes.

So far can of air was not enough.  I didn't try with air compressor.    But it goes up and down nice.  And diaphram looks ok.

A mechanic friend of mine said sometimes on older bikes the slide gets cockeyed a jams.  Only has 50k miles.  I did replace diaphragm a couple years ago.

I realize this is an old thread.  But I discovered it with google and someone else will too

I have other bikes to ride.  So I am also going to order some cap head allen to replace screws.  I do have JIS screwdriver.

Yes

Took my 2001 CV44 carb with a CV40 slide and diaphragm from J&P today, ran great.

I am going to have my old one. If I ever had to I might be able to sand the marks out.

I added allen cap screws thinking it may be easier to get bowl or top off with all key than a screw driver.  Put a little anti seize on the bolt.

Was not supper happy with the kit I got, bolts were kinda long.

I also blew air in the eye brow/frown and top of front of carb and got slide to raise. I had to open throttle to get to raise.  I did see some videos on line where they did not open throttle.  So maybe I was just to sheepish with air.

Don't bother, just buy new. Yours likely has a pin hole that was causing issues, not the marks. If you put a bright light behind the diaphragm and gently stretch it out, you'll probably see the hole.

I was getting swoosh noise when lifting slide.  Do you think I would get that with hole? 

reason I am saving, it seems harder to get carb parts.  But this for $40, I just replaced it.

It's possible to still "swoosh", as it is a very small pin hole or tear, just enough to come into play with high vacuum.
