You will be limited to 120cc in the 100 class. Powroll offers a bore in kit for the 100 crank that boosts the displacement to 118cc. They offer a high compression piston recommended for racing and a low compression for pump gas but you won't gain much in the way of power with the low compression piston. These bikes hold thier own with the 2 strokes because of the smooth torque and flat power band.
