I have a 1998 SuperHawk for sale, bike was recently crashed during a test drive. I was looking to sell the bike prior so I'm in no position to want to fix it so it may serve someone on here better purpose. Bike has 8000 miles. Engine, Trans and clutch are perfect. The pipes have been damaged...

Does anybody know of anything i can do to my heads to get more power? Besides cams and all that...i ported and polished exhaust and intake. Any help would be appreciated.
