GSXR4, what kind of performance increase can one expect from just the cams?

they let it rev better all i can say is i ran the b4 cams in my spare motor and had to take them out and put my gsxr 4 cams in cause it just seemed like something was holding it back! compared to when i had the gixxer motor all together. In case everyone doent knoww i run a stock b4 salvage motor that i did a valve job and re rung it milled the cyclinder 10thousanths and put my gixxer cams in it! have raced it for 2 years now and seem to be almost ready for new rings.

Somebody snatch up these cams before I get into trouble. I'd be all over 'em, but if I buy any more parts for the bike I'll be sleeping on the couch!

If I get mine started soemtime soon I'll take a set. I still need to find out if the bike even runs at all. Waiting for carb parts. Emptied the oil - LOADED with gas, not a good sign.

Could just be a bad petcock that was allowing gas into the motor. Hopefully they didn't run it like that!

Actually I'm not sure how they were running it. The fuel tank doesnt have a cap (no vacuum) there is no choke cable or even a housing for it (the round part on the end of the high/low beam/horn switch).

So I have no idea how they even got the thing to run.

ANybody have a clue?

The fuel tank doesn't actually need a cap to run. Basically the fuel is gravity fed into the carburators, the petcock is turned 'on' by a vacuum line that runs from it to the intake manifold.

The petcock is basically a vacuum operated switch. Apply vacuum and fuel flows via gravity, remove vacuum and fuel stops. At least, thats what is supposed to happen. Most of these old petcocks leak now, be it because of worn seals or torn diaphrams. Two ways to fix this a leaky petcock.

Add an in-line fuel shutoff (assuming fuel isn't actually leaking back down the petcock vacuum feed, which it can do).

Replace the fuel petcock.

IF I ever get the bike running and it doesnt need major mechanical work I'll probably just put a Pingel petcock on instead of teh stock one.

Thats a big "if"
