does it have points or an electronic ignition, and how do you setthe timing? anyone know?

Its electronic ignition. Use a regular 12v timing light ( itll need to be powered by a seperate battery ). Start the bike, let it warm up, hold the rpm steady at about 3000. There should be a single line or pointer on the stator plate ( its to the left of the flywheel ). There should be 2 or 3 lines on the flywheel: if 2 lines, then centered between them, if 3, then centered on the center one.
