I am helping a friend that has a 07 kx250f. He was just riding along at a moderate speed and the bike just died. From the description it sounded like it was electrical like it lost spark. Checked for spark and that seems good. Carb is getting fuel and it seems that a fuel related problem wouldnt have died so suddenly. I noticed that I can fairly easily turn the engine over by hand with the kick starter. Almost seems that if the bike were running properly that I could start it by hand. I am used to bigger bikes, is this normal for the kx 250f or does that seem like low compresion. I am planning on adjusting valves and doing the routine stuff. Would like to know why it suddenly died and why it wont start before I start tearing into it so I know what to look for. At least have some hints of what to watch for. I am not real familiar with the kawis. What do all of you KX gurus suggest that I give attention too.
