should i put a big rev box on it. it puts it at 1200 rpm and ups it by 3 hp. rate now have hmf pipe run on it.:noupstoday01::noupstoday01:

A rev box will help some but anyone in there right mind doesn't rev them that high.The only good is that one of those modded cdi boxes does change your timing curve thats why you make the 3hp or whatever it is.
