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.

[Hossamania]

Not sure which port that is. Do I blow air into it, or across it?
The carb should come apart anyway, I want to change the needle.
I am leaning toward it being a fuel issue over an ignition issue. At least I hope so, easier for me to repair.

Very good, I know what you're talking about. Thanks

[Hossamania]

Well, Max nailed it in #3. Thank you Max. Shoulda listened to you right away!  The vacuum piston diaphragm is ripped right at the plastic. Interestingly enough, there was a discussion a few months ago about the burn marks that always turn up on the slide where the diaphragm meets the plastic. Well, that's where it ripped, right after I said they all do that I've never had a problem.

So that is the good news, cheap, easy fix.

The bad news, it is an obsolete part, CV44 carb.

Anybody know where a guy can find  part # 27552-99?

[Hossamania]

Oh, and will the slide for the CV40 work? Different part number, I know, but heard it might.

Nope, according to CV performance.

[Ohio HD]

I don't know if you can get that at all.   

           S&S Super?   

[Hossamania]

Well, the SnS does look,pretty cool!

I was hoping this would cost $50. Not $500.

[Hossamania]

Will a Mikuni 45 fit on a SE 44 intake? You know, just in case?

Yep.. You need to add an adapter from the carb to SE backing plate..  A 42 will also work if you can get the rubber seal that adapts the HSR42 to the SE manifold.. Used to come in the manifold kit IIRC.

Yeah, I get that, them damn decimal places....

 You may be able to get a regular diaphragm from any CV40 and carefully remove and transfer the rubber to your slide- use dish soap as lube so it doesn't tear.

[FSG]

Yes it will.

Carburetor Rebuild Kit Part No. 27554-99 is for both the CV40 and the CV44

and the Vacuum Piston P/N 27552-99 is included in the kit.

So the slide isn't available, but the rebuild kit is? I will try and find one.

I'd be willing to give that a try.

Seems to also be obsolete.

[Hossamania]

I will take my slide to the dealer tomorrow and see how it matches to the  40.

just get a CV40 from ebay and pull the slide from it, I've a couple here but I'm too far away for it to be worth sending

I've still got my old 40, but I'm going to leave that unmolested. I will just pick up a new slide tomorrow.
Thank you to everyone for your help. I will update my progress.

[05fatboy95]

Hoss, if you don't find it let me know, I have a couple partial rebuild kits laying around in the garage. I will dig through them and see if I have one for u.

Thanks , do you have 44 slides maybe? I can get the 40 slide, going to compare it to my 44 slide, hopefully close enough.

[05fatboy95]

I will dig through it all tonight, if so its yours but idk until I look.

[PoorUB]

Wow, 15 year old bike and simple parts are no longer available!? Makes you wonder!

[koko3052]

Hoss, there's a guy in Fl that sells just the diaphrams, I've bought a few for spares & of course FSG is correct, the 40 & 44's are the same. Sorry but I can't remember his company name, but google is your friend.
