How to quiet the valve of Wuyang Honda

When the car is cold, just adjust the valve clearance when it is cold and there is no sound.

The valve sound of this engine will change with the temperature of the engine. Generally, the car will get louder when it is hot. Check the valve when the car is cold and adjust the valve clearance when it is cold. The valve clearance will automatically increase after hot car, which is a common problem of this kind of engine. Using better quality engine oil (not engine oil with high quotation) can reduce noise. But pay attention to the valve clearance must not be adjusted too small, otherwise it will increase the loss of camshaft and valve rocker arm.
