54mm Big Bore Kit Change 110cc to 125cc Cylinder Piston Ring Gasket Set for Dirt Bike ATV Honda C100 C110 CT100 JH110 DY110 QJ110-9 ZS110 152FMH

Just what the doctor ordered

I didn’t buy this kit here but got the same kit from somewhere else. This kit will not make 125cc’s out of a 110cc engine. The 110cc uses a 49mm stroke and the 125 uses a 54mm stroke with a 54mm bore. Using this kit will turn a 110cc into about a 114cc. It’s a very nice kit and worth it for the aluminum cylinder itself but false advertising takes a couple stars away.

Brings your bore from 107 to 114cc with higher compression. You will need to do some grinding if you have a bottom mounted starter.

My bike only lasted 4 miles with this kit
