Unless you find a small "restricting washer" between the head and the exhaust pipe...Then usually there is no easy means. In the past these "washers" were put in place to reduce performance, the idea was as the riders skills improve the washer can be removed. It also was a way for parents to keep their children from zooming flat out everywhere.

sounds like you have too much voltage coming out from your battery, mabey a faulty regulator. The easiest way to test this, is to get a multi - meter, and check the volage output at the battery, with the engine running, at idle should read about 12.5 - 13 volts. Then rev the bike up, and seeif the reading changes, it should not go more than 13.8 or 14 volts max. If it does, then i say you have a faulty regulator/ rectifier.

first major restrictor is in the exhaust pipe. Take off all the securing nuts and bolts to remove the pipe. You will notice in the end of the pipe that fits to the cylinder head there will be a washer that reduces the bore of the pipe. You will need to grind away the weld that secures this washer, clean out all metal particles and refit pipe to bike. This will dramatically improve the performance. Hope this helps' Alex.
