The Big Bore Kit is essentially a new engine! What do you get?
New Cylinder,Piston,and Camshaft,gaskets,installed and tested
Why? It makes your 49cc engine a new 70cc engine,adds 50% power and increase to speed!
Price includes installation.
The installation of any kit that changes performance values,such as this kit does,voids the manufacturer warranty.
But IT GOES VERY FAST! You will no longer need low gear as the torque increase is such that it will not be necessary.
We will be offering a demonstration of how to install the Big Bore kit on YouTube. Click a link below to view.
