continuing carb (?) problem... sherlock holms, any ideas please?

[Steve]

Still having a major problem with acceleration. Problem (continuing): The bike runs fine up to about 1/2 throttle, then it cuts out if I don't reduce the throttle. This only seems to occur when I'm riding it; if it's on the stand and I give it throttle it revs up fine. Also, it's much worse in higher gears... I can ride and give more throttle in 1st or second. I've completely disassembled and cleaned the carb twice. I've also disassembled and cleaned the petcock. But the danged think keeps cutting out on me when I ride it. Ideas? My frustration level is the only thing that's getting a lot of gas at the moment. Thanks, guys, for any ideas. On Sun, 02 Jan 2011 23:53:18 -0000 "Steve" writes:
