I purchased a new stator plate with working coils and condensor to alleviate my weak spark, and I need to get the cam off to replace it. (I already replaced the spark plug coil, so I know it's not the problem).
The problem is, the cam seems threaded on to the crank shaft and there isn't really anything on the cam that a wrench can go on. There are the slightest flat spots on either side, and the wrench barely went on and nearly stripped the hell out of them. Since it is threaded on, a puller isn't the solution, unlike on other Motobecane engines.
How do I get this cam off??
