Have you checked the coils with Ohm meter? You should have .03 Ohm on the primary side-plug to plug on the secondary you should get somewhere around 6000. If you have access to a scope disconnect the coils-hook scope up to the leads coming out of the igniter going to the coils and see if you get a nice square wave-you can also check sidestand switch[bypass to ground]this has been a problem for some.I hope this helps-Later!
