Our new release of the Zenoah FULL CNC MACHINE 36mm bore 29mm stroke Full PRO MOD cyl kit with NO CRANK

The 29.5 is a great all around performing  and can be used for most applications. The 36mm top end with a 1mm stuffed crank is a great balance of torque and very high rpms.

To start we NOT machine the combustion chamber for a proper squish clearance and compression ratio. We learned a long time ago that doing our type of mod is the best way to do it with out stacking and/or using thicker cylinder gaskets does not make power. From there the cylinder and piston is modified and the transfers ports.

Full CNC machined cyl and piston and We ck every cyl and piston on the degree wheel to set to our spec.This way we know it's 100% when it leaves our shop.

We at Gizmomotors one of the leading marine engine builders in the world we have come with our knowledge to bring some of the best RC engines and upgrade kits to the RC world.We dont brag we just show.Please check our engines or upgrade kits and you will see there is no better value and workmanship in the world.No Cookie cutter machine work here.

Just to give you a update. I have now released my new port design on zenoahs. I have been testing for months now. As i seen that some company's are trying to copy us. But this new design it will be fun watching them try to copy This can not be copied very easy.The new design will improve though out the power band.

This kit is a 4 bolt kit and we prefer the zenoah or the RCMK crankcase
