[QUOTE="ossagp, post: 204921, member: 1650"] two things come to mind, and you wont need shims on any of the air cooled dirt bikes that i know. if you find the flywheel rotor it should be marked with a few lines and letters. you should be looking for the one marked T. turn the rotor with a wrench and line it up with the case mark (usually pretty obvious) and see if it is actually on the top dead center of the compression stroke or the exhaust stroke. if the valves are depressed at all, turn the crankshaft a complete turn (360 degrees) and check again. if you cant get a loose feel in any position then you know they are too tight. there are adjustment screws and nuts for each valve. if you don't have any exact settings you can do as I do and start at .002". I think your problem is more likely coil or stator related but you will need a cheap multi meter and and some specs to make sure. in the meantime y ou can set the valves and clean the carburetor and set the float. if nothing else it will run better in the 10 minutes it takes to die. cleaning the fuel filter and screen in the tank is also something you should try.
