I put a degree wheel on my PK80, what's it gonna run like??
Transfer 120' ATDC
120' Duration
Exhaust 110' ATDC
140' Duration
Intake 124' Duration
Measurements are with no base gasket. Crank trued with dial indicator. Crank case matched to transfer ports. Cylinder ports cleaned up, but not changed. Piston skirt trimmed to clear intake port. Intake port matched to Manic manifold. SHA clone carb. Piston comes to top of cylinder, so squish will be head casket. Expansion chamber not made yet. Wondering if anything looks wrong here. What RPM/power characteristics to expect so I can make the pipe right for the engine.
Thanks!
