Optimal adjustment method of Honda vs Eagle 150c valve of motorcycle.

There is only the right way to adjust the valve, and there is no "best" way. The right way is the best way.

Adjust the valve clearance when the engine is cooling. Remove the two plugs on the cylinder head cover and the magneto cover, rotate the magneto to obtain the correct timing, and adjust the valve clearance to the specified value. The intake valve clearance of Honda Hawk 150 in Sundiro is 0.08 mm, and the exhaust valve clearance is 0.12 mm. Just adjust it to this value, and you can't just adjust the valve clearance for the so-called "silence". The engine has some "valve noise" similar to the large valve clearance, which is not necessarily caused by the large valve clearance, nor can it be solved by adjusting the valve clearance, although some of them are benign normal sounds. If the valve clearance is adjusted too small, it will cause difficulties in starting, weak driving, unstable idle speed, easy flameout and wear the valve rocker arm and camshaft. The main purpose of adjusting the valve clearance is to ensure the normal operation and performance of the engine, not the so-called "mute".
