new type of piston mod ! well for the china girl lol its actually used quite often on the zenoha model airplain motors and thats where i got the idea.
its a copy of the zenoha Viper piston mod and its basicaly a piston vent drilled in the side that vents the trapped hot gasses from under the piston out into the transfer ports to keeep the piston cool at high rpms and to keep cool fuel and oil flowing over the needle bearings.

edit... i talk about jug mods for about 3 min first if you wish to skip to the piston mods

i would love to get my hands on a zenoah 50 cc or even a 42cc motor !!! those things are built like tanks and handle well over 10,000 rpm all day long all wile pushing out 5 + HP !!!! i have seen 50LB rc monster trucks rip around at 60 MPH
