Ripped carb diaphrams repair?

[Guest]

I finally got some 34mm gsxr carbs and I have put them on the bike and it's running weird. Well conclusion I have come up with is the diaphrams are leaking/ripped on 2 of the 4 slides. What product would be the best to fix the diaphrams? I think the diaphrams may be seperated from the slides where they connect because I cannot see any actual rips just some places where they are worn a little and I think if there was just a pin hole leak they would still lift. I am holding the vacuum on the intake side of the carbs with the slides open and one slide lifts ~7/8 of the way and the other about 3/4 and the other two do not lift at all. I have switched the slides around from carb to carb and it still does it with that slide so it's not the bodies that are causing the problem. Anyway I think I'm going to try to seal the diaphrams. What do you guys suggest?

Replace

I think you'll find that the only satisfactory "fix" will be to replace the bad diaphrams. Carb racks are abundant on ebay and you should be able to find a cheap set where you can get some that are in good shape. Also, you'll end up with some other parts that may come in handy 'down the road'.:-D

My suggestion? Get new diaphragms. As chuckycheese suggested, you can get another rack of carbs, or you can break down and just get new diaphragms. If you get all four, you won't have to worry about them for another 20-25 years. Shop around, I have seen prices range from $65 to $130 for stock 850 carbs.

however you can do you own cost benefit analysis

If you are going to throw it away anyway it can't hurt to try a repair first.

I've used the spray rubber as a temp fix and it worked until I found some other diaphragms.

Will the gas eat the spray rubber?

Only use it on the top.

The spray rubber? As an alternative to a diaphragm? :-D

I apologize for being juvenile, but I can't keep a straight face.

Seriously though, I actually want to know what product you're talking about.

The diaphragm takes too long to install. Ruins the mood. :-D
Napa has the spray rubber.
