Bicycle Gas Engine Kit  4-Stroke 49cc

This 4 cycle engine is a HUASHENG motor. A new model just developed recently. The way it sets up on a bicycle is very similar to our 2 cycle motors. The motor sits on the middle triangle frame, and pulling the rear wheel. It does not need oil/gas mix and is much more reliable that 2 cycle motors. It uses pull start. More detail specifications coming soon.   We currently don't have an installation instruction for this kit yet, but it includes a manual of the motor. We will send alone installation instruction of 2 cycle engine with it, since they set up about the same way. But we do have a installation video available as following:   49cc Installation Video Instruction In Stock.   $279.99  FREE SHIPPING Quantity:
