The new pistons are in for those that requested them.

56 and 57mm varieties...get'em while they are hot.

Well actually...if you haven't requested them's too late. But I can order more if there is sufficient interest from the slow bikes ...errr.. people that don't have them. To tell the truth..I'd prefer it if only rich people ordered them cause so far I lose money on every set I sell. But not much, so don't go making charity offers.

Here's a pic before polishing.

Changes to the 56mm type are .015" deeper valve pockets so users should be able to use a thinner head gasket and still have .005" more valve/piston clearance. Claying is of course highly recommended before choosing your gasket thickness.

Changes to the 57mm type include .015" deeper valve pockets and setup for a thinner wiseco ring set. And of course 1mm larger for 209cc.
