Piston specs

The specs for the 700cc from the manual call out to measure the piston up 15 mm from the base or end of the skirt and measure from Front to back of the piston (exhaust side to the intake side). Diameter should be 70.425 - 70.430mm (2.7720" - 2.7728")<-- NOT a typo. Piston to cylinder clearance should be .070 - .075mm (.0028" -.0030").

The cylinder bore should be 70.5 -70.52mm (2.775" - 2.776") Taper limit should be no greater than .05mm (.0019"), Out of round limit should be no greater than .01 (.004").
Specs are in the other thread too. Tracy
