dazzer you need to get a big bore kit and get a gear up kit too along with upjetting or getting a bigger carb and light weight rollers and an nexpansion chamber exhaust the bike will fly up to speeds of around 75mph have you taken the spacer out from the variator and cut the disruptor off the front of the exhaust ??????? these are two of the standard restrictors.
