Here is an atc 70 and guy brought in,, the stock engine was dead, so I modded a PP90cc engine in it.
This is a little performance 90 , uses the daytona style outer rotor that I machined the pull start to work on even the gear selection indicator works, milled the intake so the 22mm carb would sit right between the frame and tank, added a remote petcock, modded the footpeg mount,made CDI mount,modded the pipe mount, and a few other small details.
Had a pretty good time testing it out! realized real quick that sudden turns are done at a pretty good risk .
what a wheelie machine!!
