I'm running a kitaco 75cc cylinder kit and everything else in the motor is stock, even the pipe. Everything on the chassis has been changed. I can't help but tinker on it... Full Hydraulic inverted front end and extended swing arm with a Works shock and then I matched up disc brakes front and rear. These were the last mods... Waiting on 12 inch wheels and motard rubber. I have a 20mm carb and was considering putting it on... Any suggestions on jetting...? I'm in Austin TX. at around 400ft elevation.
