What year is your S1? I have a '96 that I'm turning into a race bike so I have lots of spare parts. Hit me up if you need something. I'm using the engine, frame and wheels, that's about it. My isolators were original so they're no good. I have some stuff on eBay check it out. I'll ship at a discount for a fellow bueller. My seller name is jcarrc51. I have other stuff that I haven't listed yet.
