Well since Gilad got things started with his RS I thought I'd put mine up too, still in progress but soon she will be on the track. I will try to keep the posts up. Willow Springs has a great kart track to play on. Perfect for bikes up to 125cc. I found a 2001 RS50 was in pretty good shape on the craigslist here in L.A. A few little things came up like broken and crappy rewelded engine cradle ,but thanks to AF1 I have been able to pick-up spares pretty easy. First job was to strip down and replace anything needed and find out what had to be orderd, parts are hard to come by in the states. AirTech bodywork made me a nice race nose and tail,I was still able to use the side panels and chin fairing. Removed all the wires not needed. Race Bridgestones 90x110. New top clamp,clamp-on bars quick turn throttle. Engine had already been tuned up to 75cc but still had the stock carb so I shipped out the Keihen 28mm. Removed the starter and oil pump fabricated some block-off plates (THOSE PLUGS NEVER WORK) Replaced the fork springs and oil for my large self (205lbs without gear) Went with a new i-shock from a KDX110 so that I can keep the front end at the stock hight and lift the rear end a little,again so my size does not bottom out the suspension.So thats where I'm at now. Getting ready to paint the bodywork and put it all back together hope I will have a track report soon.
