:cool: I have a 1974 TL433 Yamaha with a hydrolic clutch system can i convert it to centrificle? also my sled keeps blowing lights at high rpm can some 1 help me? thanks.

Your lights are likely blowing out due to a bad or poorly grounded voltage regulator. As far as the drive system, I don't know a lot about Yamahas but find it unlikely they would design a platform only for hydraulic drive. I would say a conversion is possible, you just need to find a sled with same platform.
