Does anyone know what the dyno chart looks like regarding stock h.p. @ the rear wheels for a 07' Pro Mxr 90?
What do most Apex National motors produce in horsepower?

I have heard that the Pred. 90 is about 4-5HP stock. The Apex comes with more for sure so I would suspect about 6-7HP or so. I'm no expert on this but an educated guess works sometimes.

I've seen stats that read anywhere from 7 1/2 to 9 1/2 hp in stock form for a 90.......

I just had my sons 08 mxr 90 lt dynoed at Hetricks, on Wed. I had them install their air box system on it. It put out a little over 9hp, with the box on, they did not do a run with the stock air filter on it, though. I guess add another hp or so. Rich did say that with a head, porting and a crank, he can get aroung 15hp out of the motor.
