How to adjust motorcycle valve+video tutorial

First, how to adjust the motorcycle valve:

2. feeler gauge: select a feeler gauge with a specified thickness, insert it into the valve clearance and pull it back and forth. If you feel a little resistance, it is appropriate to clear the warehouse; If there is no resistance, it means that adjustment is needed. First find a small wrench to turn the adjusting screw, while pulling the feeler gauge to feel the resistance state, and then tighten the adjusting nut after the clearance is appropriate.

However, it is inconvenient to use the feeler gauge in actual operation, that is, loosen the nut, tighten the screw, and then plug the feeler gauge, and the loose screw may be mishandled.

3. Nut: When you screw the screw by hand, you will feel resistance. You don't have to screw hard to the end, and you don't have to go backwards. At this time, the clearance is almost the best, and then tighten the nut.
