Fits 66cc high pin piston engines with 47x38mm bore and stroke.
This SkyHawk Cylinder deck height is 69.5mm for 38mm stroke engines and gives an exhaust port timing of 143 degrees and a transfer port timing of 120 degrees!
Heads up: DO NOT USE with 40mm stroke engines that have a cylinder deck height of 70.5mm. Even if you add a 1mm extra bottom gasket the port timing will be off and will result in a poor running engine. Therefore, don't do it.
Intake and exhaust port stud center line to center line spacing is 40mm.
