Ghost Racer 7G T-Belt Drive V-Mount Kit Special Edition with HuaSheng 49cc 4-Stroke Engine

This kit features a 49cc HuaSheng motor with Clutch Flyweight for 5/8 Keyed Shaft. Using a belt drive single speed transmission for smooth acceleration. This kit includes a 2 piece wide crank kit, if the bike has a 1 piece crank set a conversion bottom bracket will need to be used (not included).

4 Stroke engine kits are very different from 2 stroke kits in many ways. Building a 4 stroke bike is a little more involved then the two strokes, the extra effort is worth it. Pull start engine, not push start like the 2 strokes. Overall this type of engine is more reliable with more power and torque. With some of the larger cc motors, the top speeds far exceed the 2 strokes. Since these motors are larger in cc they are also larger in size and weight. Almost all bicycles will need to use a wider crank setup to clear the motor, the stock arms and pedals will hit the motor when pedaled as a regular bike. One piece cranks will also require a bottom bracket conversion set as well (not included).

This style of the engine might need slight modification to the bikes and will not fit all frames.

Advantages of 4 Stroke Bicycle engine kits:

• Use straight gas (no mixing oil with gas)
• More Horsepower
• More Torque
• Quieter Engine
