I recently Just picked up a Lifan G10r (LF100GY) for $50 from a neighbor. Needs a little bit of jetting and tuning to get right and a kickstart shaft. No big deal. Im new to chinese bikes and im really aching to turn this in to sort of a pit bike or backyard warrior kind of thing. Id like to upgrade it a little bit with exhausts and such. Are there any bikes that are totally compatible that I can buy parts for? or is there a good site to buy these chinese parts as I have already broken the rear fender off. Any mods you could suggest as well? Thanks alot!
