I just got this LT500 dont know the year? It was said to be built by Duncan racing but has no markings on the cylinder? It has a power head and PT pipe. It has a very weak and intermittent spark It will be weak then all a sudden glow bright then weak again? I pulled the Flywheel looks to be lightened? It has scratches on the inside of it like it was rubbing some chunked up spots still feels smooth but you can see it? Guy said it was a bad stator? I have an 87 and 91 LT250 will the stators from one of them work. would the stock 250 flywheel fit? Will it hurt if it is not a machined flywheel? This bike gets my blood pumping just looking at it feels super tight all around except the spark deal. What plug do i need to run?
Much thanks to you all up front I have always wanted one of these and now she has arrived

 

check the coil and plug cap
