Before I start tearing into my bike, PLEASE give me some ideas. I have an 04 with 55,000 miles and having problems with it running. It has a full yosh and a gear. HAD a PCIIIbut i took it off because i thought that was the problem. It runs great until it warms up. Then when the bike heats up, it just wont go. On the way home tonight it would only turn 12k and that was at 3/4 throttle i guess. If i turnd it anymore it would fall flatt on its face. Almost like you just cut the fuel to it. ANY suggestions? and would you put the PCIII back on once this issue is fixed? thanks for any help.
