Z577953201 2mm STROKER CRANKSHAFT Image

#Z577953201 Stroker Crankshaft 30mm(+2.0mm) to suit Zenoah and other Marine Engines.

Fully assembled Crank halves, Conrod, Crank Pin and Big End Bearing

This part is for modifying your Zenoah engine and requires modifications to the original cylinder on the engines to accommodate the +2mm stroke.
The crankshaft reduces case volume, increasing primary compression and therefore increasing power. The 2mm stroker crankshaft will increase the Zenoah marine engines up from the stock 28mm stroke to a 30mm total stroke. This Stroker kit will increase the displacement of the Zenoah G231PUM engine from 22.5cc to 24.1cc and that of a Zenoah G260PUM from 25.4cc to 27.2cc
Note - When using on a Zenoah brand motor, no additional parts are required but this will only fit other engines if the top end as well as other modifications are done and also in some cases the addition of Zenoah parts.
