Put a stiffer clutch spring in it, Install K & N filter chargers on the carbs, (you MUST rejet it after or you'll run the chance of frying the motor!!), Aftermarket pipe. Cheaper than a Crank Shop engine, although they SCREAM!!

do your carbs have the equalization tubes running to the air box? if so K&N's might not help much, in fact they might hurt, of coarse that all depends on if you have them or not. if you dont i would invest in them.
