I would just find someone with a gps to get your top speed...as for the ponies, you're gonna want a dyno run...I dunno about where u r but around here I believe you can dyno your bike for around 30-50 bucks. and they'll be able to tell you if you need to change your jetting,timing,also it will tell top speed,max hp, rpms, and they will even be able to simulate a little race with the stats your bike puts out. Its pretty cool if you have some extra jack layin around.
