[QUOTE="Peezy, post: 163573, member: 1090"] Okay, I have some weird problems with my bike. I recently had to tear it apart to fix a gear in the transmission. I put the engine back together and it started right now and i ran it for about an hour around my neighborhood. It was working perfectly. Last weekend I took it to the track and it started and about half of lap one it just died. Would not start at all afterwards. It sounded like no spark/gas. I tried to bump start it down a hill, it tried to start but nothing. Here are the things i checked. [LIST] [*]Spark plug looks clean and has spark [*]I cleaned the jets and made sure it was getting gas and bowl not stuck [/LIST] It feels like it has compression, but I may get a pressure check to confirm this... But what other things should I look at? My guess would be timing but that wont make since. It was running perfectly a few days before then now nothing? I need ideas where to look for the problem.
