from most of what I've heard it helps on the top end. I have my bike set up for low to mid and rev the bike enough to tell. Plus if you go with porting to get full effect, go with valves stiffer springs, cams,and high compression piston. I would do it all or don't do any. Remember, knowing you bike and spending the time to set it up, and I mean really set it up will be your best bet in gaining maximum performance. Good luck:thumbsup:
