Through UPS we offer many shipping methods and for International and Canadian shipping we suggest UPS STANDARD, (2-6 days; does not cover Customs Brokerage, Duties, and Taxes… these are charged to the consignee on delivery). We have found that this is the cheapest way to send packages to Canada.

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

The bicycle motor engine is a 2 cycle design, therefore, a gasoline/oil mixture is necessary. During the break-in period (1st 4 tanks of fuel, the ratio is 16 to 20 parts gasoline to 1 part 2 cycle oil. After the break-in period, the ratio is increased to 20 to 25 parts gasoline to 1 part oil. 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.

The buyer may need some basic hardware skills, tools, and it takes roughly around 2-3 hours to install and to do some adjustments and fine tuning.
