Machined Zenoah Crank Case With 2mm Stuffed Crank

This is a brand new machined Zenoah crank case with a stuffed 2mm full circle crank shaft. We have opened up the I.D. of the crank case for proper clearance with the stuffed crank. This bottom end can be used with a G230PUM or a G260PUM top end. The top end either needs to be machined for the longer stroke or gaskets can be stacked. This bottom end comes complete with a machined Zenoah crank case, stuffed 2mm crank, bearings, seals, case gasket, and bolts.
