first you will have to see what the rule book will allow. it may not allow any modifications to the engine, if you are racing in the class. otherwise, ty to get a different cam, mill the head and open the ports in the block if you can. you might also try a diffferent bigger carb. although i think you can't do this stuff .

change the clutch to 1 that has less teeth and put a smaller spocketthis will give more top end but it will hurt the tork on the lower end though.

USE A LESS FRICTIONAL FOOTPRINT OF YOUR TIRES

MORE PRESSURE IN THE TIRES

ABOVE ALL--PLAY IT SAFE WITH WHATEVER YOU DO!
