Fuel for the Thrill: Please note that gasoline-operated products are not compliant with the Environmental Protection Agency (E.P.A.) or California Air Resources Board (C.A.R.B.) for on/off public road use. These products are designed for racing (closed-course competition) only.

A Note on Engine Size: While we label this engine as "100cc," its true displacement is 78.6cc. This discrepancy in measurement standards arises from differences between Eastern and Western engine measurement methods. In the West, engine displacement considers only the cylinder volume, while in the East, it includes the combustion chamber's volume. All "100cc" engine kits on the market today have a displacement of 78.6cc when measured by U.S. standards.
