Question: How much weight will this engine kit add to a bike?
Answer: The engine kits will add about 26 lbs to your bike. Note: We suggest a 26" Men's standard V frame bike. 

Question: What fuel do I use for this engine kit?
Answer: This 2 stroke stroke motor kit requires an Oil and Gas Mixture as follows:

When New: 16 to 1 (8oz per Gallon) 
After 2 Tanks Of Break In: 32 to 1 (4oz per Gallon)

You should get 100-150 Miles per gallon and achieve 30-40 MPH depending on climate, altitude, bike weight and rider weight

Question: How do I start and stop my bike with the Raw Racer III?
Answer: The starting and stopping of this two stroke motor kits is this: 

You can still pedal bike like normal with clutch lever held in or locked in with button. 

To Start: It's just like riding a bike normally, hold in the clutch and pedal the bike to get some speed, then release the clutch to "Jump Start" the motor. If you know of or remember jump starting a Manual VW Bug this start method is the same.

To Stop: While the engine is running you can hold in the clutch and the engine will idle. Push the Kill Switch on the throttle to kill the motor. The clutch must be held in when the bike is in motion or the motor will keep running.

Bicycle Requirements:

This bicycle motor engine kit fits most Mens 24" and larger bicycles which includes mountain, cruiser, chopper and road bikes with a V-frame with at least a 8.5" height clearance for the engine. Larger frame size requires drilling into bike frame and use of the universal face plate.

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.
