New for 2022 our RTE Full Mod 34cc Head Kit.

After developing our 35cc and extracting huge amounts of power from this arrangement, we have decided to incorporate similar modifications for the 34cc.

These new changes allow for superior piston crown cooling, and much tighter clearances. 

The G340 struggles for big increases in horsepower over the G320 due to a number of factors.  Our new design ensures maximum increases in power across the entire rev range over and above the G320, and huge increases in torque without sacrificing reliability.

Super easing starting, precise tuning, low cylinder temperatures, and huge power.

**  Please note this head kit uses a NGK CMR7A Spark Plug  **  

You must use a RTE 2mm Crankshaft G320 (RTE Modified) or DDM Part# DD404B.  

Be sure to check your squish clearance at assembly.

This kit will fit the Zenoah G320RC cases only.

The lead time can be up to 7 days, please email for an accurate time frame.
