This monster is upgraded to make the overall size smaller. A Large 79cc engine with a CNC single speed transmission featuring a ⅝ shaft keyed centrifugal clutch. Replacing the on motor gas tank with a standard 2.0 lier frame mount tank. Also included is an upgraded exhaust adapter and chrome exhaust pipe, with this setup all 2 stroke pipes can be bolted up.
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)
