How to adjust the valve clearance of Neptune motorcycle

If the valve port is not properly ablated, then check whether the electronically controlled air door of the carburetor is not working well, whether the spark plug gap is too large or whether the spark plug is not good.

When the magneto is aligned with the T timing, the valve can be adjusted. The difference is only the thickness of two cans. If you haven't done it yourself, you should go after the sale. Improper adjustment of valve clearance will cause noise, insufficient engine power and high fuel consumption. You can ask me any other questions.
