Pipes and jetting work well on standard motors!!!
Porting ,pipes and air box convertion work well to.Any one who says these pipes are better than the others has in my mind a very narrow imagination,Every motor and every set up works differntly in different situations,and remember everyone rides differently. I have seen stock banshees kick *** before at meetings, with good riders, and I have seen stock banshees left in the dust at other meetings, Horses for courses..
Dont get caught up in all the glitzs and hype of some add on parts,get to ride your bike flat out all the time first before throwing $$ at it, and remember a **** rider will blame his bike !!!
