It starts up and idles fine, revs just fine as well. As soon as I put it into first gear or second gear it dies. Sometimes I was able to get into gear and test drive it but it dies either in 1st, 2nd, or 3rd. Never made it more than 100 ft distance test driving it.
What I've, done is the following:
Cleaned and dipped carbs, they are clean now. Took air filter out cause the engine was sucking bits of it into the carbs (gonna order one soon). Cleaned gas tank and installed inline fuel filter. Left cylinder was dead and not getting hot, so I installed new plugs fixed that problem. I thought that maybe it might be the clutch safety switch but I unhooked it behind the headlight in the bucket and closed the circuit and no change. I also tried disconnecting the side stand switch but no change. I checked for air leaks around the intake boots by spraying carb cleaner around the carb to intake and the carb to air cleaner boots, no change either. I thought that initially the clutch might be stuck and went through all the gears and rocked it several times back and forth. That did seem to help the bike shift easier. I adjusted the clutch cable and the screw and jam nut behind the small cover on the left side engine case and no change either other than better clutch handling (at least it seems so).
I am at a loss and could use your help trying to determine what is wrong. I am thinking I might need to check compression, check timing (but I do not know how to do it), or adjust valve clearances (don't know how to do that either). Do you guys think I am on the right track or should I look somewhere else?
Sorry about the long post.
