The engine was put on the dyno at Sandtrax Performance in Tulsa, Oklahoma.
It produced nearly 51 hp @9100 rpms at the rear wheels.
This engine rips. Very reliable and very fast
around 6800 started around 45hp and at 9550 it started to drop off around 51hp.

$2500 shipped obo.

very few hours on it since built.(break in time and a few rides on it, no hard racing or excessive rpm runs.)

this is a very strong motor. if you weren't paying attention and goosed it you would fly of the quad. has very good bottom to top hp and torque.
