Welcome to the forum, sounds like a project..I see the wiring harness come up fairly often on the bay, some are just too much but seen them under 50 bucks..well worth the replacement. I suppose you did a compression test, if that came out OK then timing belts should be changed and checked before turning it over., fuel line and filter, carb rebuild maybe(probably)...Yep..Lots of fun but not bad once you get to know them, cant beat the ride and power..Great Bike..Give us some pics when you can.
