DDM Racing Zenoah G320 +2mm Stroker Crankshaft (30mm)

This long stroke crankshaft is made for the Zenoah G320RC and Fujiwara 350RC engine only. This will NOT fit earlier Zenoah RC models like G290RC etc.

Same function as Zenoah part # 585816001, but with +2mm longer stroke (30mm stroke total)

Adding this +2mm stroker crank to your Zenoah G320RC engine will convert it to a 30mm stroke, 38mm bore, 34.02cc "G340RC" performance beast! By adding this to a Fujiwara FJ350RC engine you will have 38cc of displacement!

Be sure to check your squish clearance after installing this crankshaft to prevent engine damage. For this crankshaft to fit into your G320RC engine, you must modify the squish on your cylinder to accommodate the larger stroke. DDM will also be offering pre-modified cylinders for use with this crankshaft.

Note: The lower rod of the +2mm crankshaft (since it sits 1mm lower than the stock rod location) makes it slightly rub on the stock Zenoah G320RC crankcase. Before using this crankshaft, it is essential that you remove a small amount of crankcase material to free up space so the rod does not hit. Download complete installation instructions HERE.

Important Note:  This is a Tuning Crankshaft, you will need to use a thicker base gasket or machine the Cylinder Combustion Chamber.  You must ensure you have the correct squish clearnace (piston to head gap at TDC) before running. We recommend 0.45mm-0.5mm for performance and safety.

Fits Stock Zenoah Flywheel and Clutch backplate etc. Direct replacement stroker crank for engine tuners or home engine builds!
