Kick starter shaft assembly for Viper 125-200 cc motorcycles and similar (China, Minsk): a shaft with a gear and a spring that starts the engine when you press the lever. Model: 150J.
If the lever slips, does not return or does not turn the engine over, the shaft needs to be replaced. Check the engagement gears.
- While you are at it, inspect the neighboring parts of the assembly: they often wear out together.
