    Has anyone looked into boring out the cylinder and using a slightly larger piston?

    I want to turn 80cc into 120cc by using a Husqvarna 3120 piston (60mm diameter).

    I somehow don't think that it can be squeezed into the space set for a 47mm piston.

    Hopefully, someone with engineering skills and machine shop tools will build a big bore (sorry, a huge bore) replacement cylinder that bolts on the standard bottom end.

    I would think it would be a lot easier in getting a 50mm piston to fit. Not sure who makes a 50mm piston.

    Any of the chainsaw manufacturers or any of the two stroke off-road dirt bike manufacturers would make pistons in a variety of sizes, not to mention the after market suppliers, like Weisco and Meteor and Espian, just to name a few.

    Bugger a small overbore, lets get some serious numbers happening.
