it depends what u want to do. i higher compression will limmit ur abblility to rev it real high without blowing n e thing

polarsport500-You can gain a lot of performance by tweaking what you already have like your gearing,jetting,tires and pressure,fuel,cdi,and you may want to try big guns new rectifier.We put the big gun rectifier on my wifes 440 and it made quite an improvement.As i am finding out you can make a lot of little improvements that add up to a lot of big performance gains.
