got a question for all of you mechanics. this is an 86 KDX 200 and it has spark so the ignition is good, though the bike still dosent start. the gasket in the top end was replaced and has good compression in the engine. the bike was running good and died one day and never started after that, so what could be wrong here? is it just not getting gas though you can smell a hint of gas flowing threw the bike so im not sure if thats the problem eather? but if any of you can tell me whats going on here thanks.. oh and how do you do a low end copression check on the engine?
