Title: Is Balanceing needed when changing to 20 over pistons ??
Post by: Peter on August 14, 2008, 04:23:09 pm

Is Balanceing of the rotateing assembly(crank rods pistons) needed when installing larger and newer pistons..also the rods are from another motor

It would probably be a good idea to get the individual rods balanced relative to each other, and the pistons themselves.

Yeah, and new rod bushings get installed and sized to the piston pins so it's nice to make sure rods still balanced when that's done.
