Hi, i have a pit bike with a 125cc lifan engine at least it's what the cover says, at this moment i have a 54mm piston with a 14mm pin, i bought the bike used so i don't really know if it as been modified or not, the question is, the piston is scrap and the barrel is scratched, i can't repair the barrel because i can't find a piston larger than 54mm with a 14mm pin, all i can find is 52.4mm piston, and 55mm piston but with 13mm pin, am i looking wrong or what?
thanks
thanks
