Wuyang Honda Fengxiang 125-N motorcycle with what wrench to adjust the valve? What is the air intake and exhaust clearance?

Wuyang Honda Fengxiang needs a flat screwdriver, 14# sleeve (rotating magneto), 10# ring wrench (removing cylinder head and screwing valve adjusting screw), valve adjusting wrench or needle-nosed pliers (fixing valve adjusting square head screw) and other tools. The valve clearance is between 0.08-0. 12 mm, and the exhaust can be slightly larger than the intake. The valve clearance should not be too small, otherwise it may cause difficulty in starting the cold car, unstable or non-idle speed, and even wear the valve rocker arm and camshaft. There is a clicking sound in the ejector pin machine. In order to eliminate this sound, the valve clearance should not be adjusted too small. Experienced people can also adjust it by hand. When it is adjusted to the left and right of the valve rocker arm, it can move smoothly (clearance), and there is no clearance up and down. At this time, the valve clearance is generally around 0.05 mm
