I've got a slight problem. About 1.5 years ago I was slightly intoxicated and went over backwards on my 83 ATC 250R, up a hill, at full throttle and didn't get off the gas until the bike was on top of me. Since then it has not run well. My best description is that if it were a four cylinder it is like its running on 3 all the time. No matter where in the RPM range you are it just sucks. I've rebuilt the carb 3 times, messed with main, needle, and idle jets, replaced the coil and the black box. Any suggestions? I think my next step is to tear the top end apart but i have a feeling its the carb /forums/images/graemlins/confused.gif... Any help would be appreciated.
