I wouldnt discourage from the motor due to runtime...people have turned the end points down some and leaned it back out to get the temps back up and gone 11 minutes on the motor on a big track.(and yes I was there and saw it)
as far as power goes...oh yeah its pretty unreal power. I will be breaking mine in tonight for racing this weekend and I will let you guys know how it goes.. also untill Orion I ran the ninja JX-21 and it too has unreal power. the only guys to show the same rip were the ones running the orion motor.
I have the orion pipe and I started with the small resrictor. we'll see how it goes.
thanks
