my buddy just ordered an air filter for his stock fiddy and we cut off the spark arrestor..will there be a noticable difference? also I went to the local honda shop and they said that getting a bigger jet wouldn't do much for the bike, but I've been reading on here about people buying them? will it help also?

 

I havent noticed any differnce with the filter and spark arrestor removed. It makes more noise.

A better C.D.I. box helps to get rid of some of the bottom end lag it has.
