DROP IT INTO YOUR STOCK ZENOAH G270RC  OR OTHER 26 OR 27 CC GAS FUELIE ENGINES AND SEE THE PERFORMANCE IMPROVEMENT. IT IS LIKE USING A RACING PORTED CYLINDER HEAD. THE BOOSTER PORTS ACHIEVE THE SAME OBJECTIVE OF INCREASE THE FUEL INTO THE COMBUSTION CHAMBER. IT IS LIGHTER THAN STOCK PISTON SO BETTER ACCELERATION AND HIGHER RPM.

VXPER MOD PISTON WITH BOOSTER PORTS

34mm Diameter

Precision machining - using CNC turning & milling 

Weight - 20 +/- 0.5 gm 

Top end diameter turned down to avoid piston seizure as your engine will be running beyond manufacturers' initial rpm and operating temperature.

Use with my MOD & Lightened Flywheel Magneto for a Lethal Combination to out ACCELERATE even full MOD RACING Engines from other suppliers. 

Also consider my MOD Lightened Piston Pin, High Speed Needle Bearings, G Clips for convenience, Anti Drag Ring for the Rear Oil Seal near Magneto, Full Circle Crank for Reduced Crankcase Volume (available in 28mm and +2 30mm Stroke )

Does not include the Piston Pin in the Picture - Selling just the MOD Piston.
