How to adjust the valve of Honda Yu Xiang 20 19?

The valve adjustment method of Honda Yu Xiang 20 19 is as follows:

1. When adjusting, loosen the lock nut and adjusting screw first, and insert the valve clearance with the specified value and the valve plug with the same thickness into the gap between the valve foot and the rocker arm;

2. Pull the plug back and forth by turning the adjusting screw. When the plug feels slight resistance, check and tighten the lock nut. If the gap changes, it needs to be readjusted.

3, cylinder block adjustment method, that is, according to the cylinder ignition sequence, determine the position of the cylinder piston at the compression stop point, so that the air intake and exhaust valve clearance of the cylinder can be adjusted. The purpose of setting the valve clearance is to ensure the normal operation of the valve mechanism of internal combustion engine. Because the valve train is in a high-speed state and the temperature is high, the valve tappet, valve stem and other parts will automatically push open the valve after being heated, which makes the valve and valve seat not closed tightly and causes air leakage.
