We have dynoed this motor with our Torquemaster pipe. we have found this to be most powerful motor on the market in stock forum hands down. the motors dynoed at 5.01 hp at 13,500 rpms and 2.02 lb's of torque. this by far more powerful then the zenoah,sikk,cy, and any 25.4 cc motor out of the box out there.
