My Katana, GSX1100F (powerscreen) engine with 38mm GSXR750 carbs, K&Ns, GSXR1000K1 race zorst is running 148bhp.

I'd say carbs, as it inproved when you gave them a clean sounds like there is still some crap in there and check the air filtter. Make shoure you balence the carbs as well, the miss GSXR1100 dose this some times will tick over but pops and bands then dieds when you open the throtel give them a good clean out and a balence and works fine, some times you just get crap fuel when you fill up.

The gsx750et have 35mm forks and the gsx1100et has 37mm forks.

Got some GS1000 crank cases welded/repaired, and some pics ATU Cam chain blade holder bit Front mount Rear mount All done for the grand sum of £50 :)

My mate has just finished his chop so I thought I'd put some pics of it up for you lot. And if anybody wants he is going to start building the frames to fit your engine :)

I'm with Pete on this one, get some CV36mm carbs the VM29 carbs can be a real pain to set up even on the gsxr750.

Had the same problem over spring on my GS1000, the battry was 6 mouths old and the bike was used over winter but in spring the bike was getting slower and slower to start tryed all the bits out like you, ended up putting a new battery on it and it now spins over nice and fast and starts first time. So I'd try a new battery.

I know I have slotted cam sprockets on my GS1000 and had no probs with the 20 teeth bit, I'm using Falcon sprockets and Andersons S3 cams. I'd recheck the timing so you don't hit a valve, I'm shoure some one will be along in a bit who knows more
