Just picked up Scott's 2000 RS125 and plan to have it out next weekend for a track day. I'm sure I'll have lots of questions and will be looking for lots of parts, as I'm a "planner". USPGRU RS Cycles TSO (just ordered my starter tool) Any other sources appreciated. The long term plan is to learn the mechanics of the motor, mesh with the bike and start looking for a 250. I had a tz125 7 years ago, made the mistake of selling it and have spent the last 7 years trying to turn turd street bikes into proper race bikes. Will keep and ride said turds, but if the idea is to go fast around a corner, an EX500 ain't the way to do that.
