133154FCL: Engine, Crankshaft, P125X Full Circle Long Stroke
This is a Mazzucchelli full circle long stroke crankshaft for P/PX and Stellas that use a reed valve setup. This adds more displacement to an engine by moving the piston farther up and down the cylinder. When used on a 177cc cylinder the engine becomes a 187cc. This is a performance upgrade that requires tuning knowledge and experience to setup correctly.
