Not to be a d*ck....why the hell do some guys have to "Run to a Dyno" everytime the add something to their bike. These are freaking dirt/sand toys. Why do you care if you got an extra 3 hp from a slip on, or 3 hp from cams. All the bs you do to bikes has had tons of R&D done to it, they have the numbers. I guess it just makes no sense to me.
