The Torpedo head kit is CNC precision modified in the United States using genuine Zenoah parts. These cylinders boast enlarged and reshaped intake, exhaust and transfer ports for greater fuel and air flow. Coupled with a relieved piston and a raised compression ratio, you’ll never use a stock Zenoah again.
TOPEDO 29.5cc head kit includes everything you will need to upgrade your 4-bolt water-cooled engine.
- CNC ported 36mm cylinder.
- CNC relieved 36mm piston.
- Piston ring, pin, bearing, washers and clips.
- Copper gasket.
- Gold water jacket.
- Sealed crankshaft bearing (optional to use).
- Pull starter and water jacket stickers.
- Bonus stainless steel bolt kit.
Fits Zenoah G231 / G260 / G290 / G300 PUM engines.
Compatible with the standard 28mm stroke crankshaft, however we highly recommend the +1mm (29mm) stroke crankshaft that comes standard in the G300 for maximum power.
Torpedo recommend running your marine engines on a good two stroke oil suitable for high RPM engines. Our preference is Motul 800 or Castrol A747 at a ratio of 20:1.
