Always a helping hand here, thanks chaps
I need only the float bowl o-rings. No luck with Sudco. Maybe a source with Kawasaki? Other thread said maybe the 2000 ZX9R had the same? I've got no sources for Kaw parts.
Has anyone tried making their own o-rings? Looks like a big o-ring with the same x-section, a razor blade and some super glue. These don't look difficult.
The OEM o-ring seal is formed to the shape of the bowl grove. Granted, it could be possible to super glue into place step by step around the perimeter then bond the mating ends with super glue.... will need to be BUNA rubber to put up with the fuel. Cross section measurement is what? about 1-1.5mm?
I have a buddy with a old 750 ZXR (or something like that) rusting away in his garage... I will have to talk to him and find out if I can take a look at the carbs

Looks similar to the shape of the KTM float bowl:

So my brass fuel inlet hose started to leak today.
Since I am replacing those and having to take the carbs completely out, should I do an overhaul on them?
I am having some similar issues justice the above posts.
Bike seems to be overheating a bit(runs sometimes at 5 bars, comes back to 4 but likes to stay at 5), bad starting (valves just done), bad fuel millage (even when I am easy on the throttle).
I did put a HZW jet kit in her. I have wings exhaust, SAS done, pre filter, live at 800 feet.
I have replaced the diaphragms once.
She's got 60,000 miles on her and I am hoping to get her to last until they bring out that new KTM 800!!! lol But I won't hold my breath.
i would buy this theory,
My stock CVRD carbs pop on decel, but my FCRs do not, they run perfect and wake it up like a spirited race bike
but for the cvrd's I have been considering getting new slide diaphragms and dont forget cut-off valve diaphragms these are very expensive and only available from ktm parts because it is a proprietary carb
i certainly WOULD NOT use ultrasound , i think that would destroy the carb body
i would check out the butterfly shaft wear for leaks and consider some repair if badly worn
also would be sure there is no play in the sync linkage
parts list i would use:
*cut off valve diaphragms
*float bowl o-gaskets
*fuel inlet o-rings
*new pilot jets
*fuel screw o-rings

Found something interesting about air cut valves in general: http://www.motorcycleproject.com/text/aircut_valve_more.html
that was a great read http://www.motorcycleproject.com/text/keihin_idle_circuits_white_paper.swf
thanks very much Mort, learned something new today
Has anyone bypassed / disabled the air cut off valve on a 950?

Not me, but I found an article saying that doing so has no performance advantage. http://www.motorcycleproject.com/text/aircut_valve_more.html
Long ago we played with it... ultimately found that it wasn't worth the effort to try to get the Air Jets corrected to make it run right... This is not to say that it couldn't be done.
Well, mine seems to be fine at 100k, if/when it fails i will plug as described in mentioned article and see how goes. Will post accordingly. Hopefully someone will chime in

Do you know if there is a repair for a leaky throttle shaft ? My rear carb shaft is pretty loose in its bore causing an air leak and popping. My temp "Fix" is to rich-in up the fuel screw. I am out 4 turns and this has temporally cured the prob so I can ride.
Thanks for all your knowledge on these beasts. You have been a valuable resource over the years.
Does anyone know where to get the fuel line o rings?? Part #53 above has three of them.
CJ Racer has them. You can look up sizes and do McMaster Carr, or O-Rings.com etc but he has the (4) of the mean greenies you need to stop the leaking
For years, when mine leak, I turn bike on & off & let them leak while the bike sits in the sun. A few cycles of this & they swell back & stop the leaking. Mine only leak if the bike has sat for any length of time
