    ProX Piston in 1200pv???

    Will a ProX piston work in a sleeved 1200pv cylinder with a clearance of .0045-.005"? The cyl came from a sbt engine.

    Yes it should. I would get a digital caliper and measure the bore. Then order the correct size piston for that bore. Pro-x has 4 different size pistons for the 1200pv motors.
