Hey Guys I was just wandering when you bore your scooter Do you have to have a big bore kit specific to your Make/model of your scooter as im want to bore mine out to 80cc from a 50cc as its Works out cheaper then reboring my Barrel and getting a new piston and small end bearing as my piston is cracked And whoever had the barrel rebored before i had the scooter Put the Old piston back in Meaning it needs doing again So All in all its works out cheaper to buy the 80 kit and ill get a little bit more speed out of it so any Help Would be greatly aprreciated
