HELP! need part for gasgas 125cc SM 2002

[sheldon]

hello, can somebody help my, i need a new barrel for my sm 125 2002. The bike is the same engine as an EC (i think). I have got a size B piston rather than the smaller size A piston so i need a barrel which will fit on the bigger piston! just the barrel please, no clyinder head or gaskets or anything else needed!

p.s. i live in england which makes it even harder

1. Take the time to find a machine shop that will measure your cylinder/barrel and compare to the piston. It's common for a cylinder to have enough wear to be able to safely use the next size larger piston. You may be set to go.

2. Wouldn't be less expenive to find the proper piston if the B piston you have is to big.
