Have you installed the carbs? If so, are you looking to straighten out a problem, or exact more performance? If it's problems, what are the symptoms?
With your displacement, I assume you do not have a stock cam.
With my smaller engine (2.0) and mild cam, my 44's work well with 32mm chokes, 50 idle, and 125 mains. I tried both larger idles and mains. At full throttle, "maybe" it ran better, but on the street it certainly didn't. Too damn rich. Ask anyone that was at the MUSR in Hot Springs last year. Belching blue flames out the exhaust. A leaking header at the cylinder didn't help.
Theoretically, you may be able to run everything larger. I've got some 55 idles and either 130 or 135 mains you can borrow it you want to experiment. Just cost you some postage. And you could probably use a 34mm choke with your larger displacement. Do you know what size you have now?
Unfortunately, this information is pretty much useless because I am no expert in the black-art of carbs, but I bet some of the pro's will jump in and school us.
