Just got back from the dyno. Disappointing results. First the air cleaners made no difference. On or off the same numbers. The engine only put out 110 HP and had 110 ft-lbs of torque. Very flat torque curve but the engine signs off at 6000 rpm. It was able to pull 8000 rpm on the dyno, but wasn't making any horspower. Peak horsepower was at 6000 rpm.
The engine does sound good. I guess I will have to work the corners a bit more.
