You can get a lot of parts from BlackWidowMotorsports.net. The light switch/killswitch can be picked up as an NOS on Ebay for $50-75
Looks like a good clean bike. Lubricate the sheaves on the clutch with graphite (oil based lubricant will collect dust and gum up the mechanism). The belts can be replaced with a Gates 6061 for about $10 from BeltPalace. That'll likely cure the slipping problems.

The Serial number (2042x). The first digit indicates the last digit of the year (2=72). The next 3 digits indicate the day of the year (042 = 42nd day of the year). Sometimes there is an extra number or two at the end, perhaps indicating the production line, or shift or whatever. The decade it was made is indicated by the style of the engine. 64-74 was round shroud with a serial plate. They went to a square shroud with the numbers stamped on top in the mid 70s sometimes (mid 74 I think). Then went to a plastic recoil sometime in the late 80s. There were other changes too, but I'll keep it simple
