+2mm (30mm) Stroker Crankshaft for Zenoah G320RC Engine
+2mm aftermarket stroker crankshaft (30mm stroke).
For the Zenoah G320RC engine only. Does NOT fit earlier Zenoah RC models!
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!!!
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. Pre modiefied Cylinders can be ordered from our suppliers on Request
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. (See photos below).
If you do not want to do this modification work yourself, we also sell pre-modified crankcases! See them in the related items at the bottom of this page. Items dd400E, dd400b, and dd400c will all accept this +2mm stroker with no other modifications necessary.
Enjoy the added torque your engine will get with this +2mm stroker crankshaft modification!
