Zenoah Fujiwara MARINE 40mm G350PUM 4-Bolt Top End Kit 35.2cc [FJK352001P]

Upgrade your water-cooled G320PUM engine to a G350PUM 35.2cc with this brand new bore up kit from Fujiwara and Zenoah! This upgrade set is designed to increase your displacement and power for the popular Zenoah G320PUM engine! With an increase in bore size to 40mm, this gives a total of 35.2cc of total displacement up from the standard 31.8cc. This cylinder set is a direct fit and requires no modifications to work. This is designed to work with the original Zenoah 28mm length crankshaft.

Includes items shown in photo - 40mm cylinder with red anodized heatsink, coated piston, piston ring, base gasket, water jacket o-ring seals, c-clips, and blockoff gaskets.

Not included will be the transfer port covers, piston pin (gudgeon pin), pin bearing and piston pin washers. You can reuse these parts from your stock engine, but we highly advise using a new piston pin bearing. You can purchase that here.
