Gas And Oil Mixture For Fuel Ratio: (Use of a synthetic 2 stroke oil is recommended.)

This bicycle motor engine kit is a 2 cycle/2 stroke design, therefore, a gasoline/oil mixture is necessary as follows:
  • When New: 16 to 1 (8oz per Gallon)
  • After 2 Tanks Of Break In: 32 to 1 (4oz per Gallon)
The engine crankshaft bearings are lubricated from the oil in the gas mix. A rich break in oil mixture ensures bearings will not cease during engine break in period.


Our gasoline operated products are NOT compliant with Environmental Protection Agency ( E.P.A. ) or California Air Resources Board (C.A.R.B) for the use on/off Public roads. Upon purchase, the buyer agrees to use products for racing (closed-course competition) only and NOT for on/off public roads.
