It’s not a mini bike motor, but I figured I’d show you guys what I like to build. Started life as a zenoah g260rc motor. I got Trevor Simpson billet reed cases for it. Doug at esp did the port work which included blocking the intake port and cutting a 5th boost port in the cylinder, lightened the piston and cut his “high rev” line on the exhaust side. I’m running a +1mm striker crank and stock 13:1 dome in the head kit.
It runs on pump 93 fuel with castor 921 oil at 25:1. Frequently sees mid to high 18k rpm. The engine is around 27cc and should make just around 7hp. It’s a wild motor
