For some cilinderskits you'll need a bigger carburator and you'll need to give the engine more oil. You can do this two ways: Buy a oilpump with bigger output. Mix extra oil in the gasoline. If you don't know how to assemble these parts I advise you to ask someone that know how to.

	This is the Polini 68cc Cilinderkit. It's one of the fastest cilinders. It has a special "W" exhaust-outlet. This cilinder works very well with a fast exhaust. You can get about 12.5 PS out of this cilinder with a 19mm Dell'orto carburator and a fast exhaust. Costs: 250 dollar without a cilinderhead
