[QUOTE="kimoajaj, post: 1094247, member: 55844"] I assume that you have , but the first thing you do is to get a new sparkplug. Even if there is a spark when you have the plug out, it might not be there when it`s put in the head. if your engine sucks false air from somewhere, it can be a bitch to start and if it`s bad it wount run at all. Check the seal behind your flywheel, for all you know it could have jumped out and is just spinning on your crank. The same goes for the right side seal (on the clutch side), however it`s a little bit tougher to check, especially if the engine isn`t running at all. If the right side seal is busted then your it will suck in gear oil from the transmission and run like a bitch and foul plugs/smoke alot. But since it isn`t running at all, it`s hard to tell. When I don`t get engines to start, and there is compression, I often poor a tiny amount of gas directly into the cylinder through the spark plug hole, then I put the plug back in as fast as I can, and then I crank it. If you do, I`m sure it will fire some how, as long as your spark plug makes a spark. Try a new sparkplug, if there`s no difference then you will have to use the evaluation method, checking everything step by step. Check the air/oil seals on the crank, check inlet rubber for cracks etc. , check reeds, even if your bike is jetted wrong, it will start, but check the carb for clogged jets/water, then check the ignition system, the best thing is probably to remove the electrical components from your bike and have a dealer measure them?. Good luck:) [/QUOTE]
