i somewhat agree with the being able to "base stuff off a dyno" but because it is never even close to being dead accurate, my bike has yet to and prolly will never see a dyno unless i am tryin to make record breaking hp or somethin like that... getting it on the actual surface ur racin on is the best bet... dyno has to many factors to figure in from different tire size from ur race tires, to traction on racing surface, to how well the chassis will balance ur ride down/up the track... skip the dyno all together and get it on the track... et's and speed through the trap are alot more to brag about then a 200 hp bike spinning all the way or havin to let off constantly cause it wants to flip over or gets squirrely and in turn is beat by a 100 hp bike that is in total control and pulls like a raped ape
