Motorcycle cleaning vaporization, power reduction.

It is estimated that the mechanic may put the plastic pad on the fuel needle of the throttle valve under the fuel needle, which will make the fuel needle position too high, make the mixture too thick, make the power worse after hot car (more fuel injection may not improve the power), and also cause fuel consumption. The adjustment of carburetor must be cautious, and it is not easy to make big changes. Now it's time to put the plastic pad back in its original state and re-adjust the carburetor. It is difficult to start the cold car, which can be solved by starting the damper. The damper is used to start the cold car. Generally, as long as the air door is used correctly, it can be started smoothly. If it is too difficult to start, you can check that the carburetor mixing ratio is too thin, the oil level is too low, the valve cannot work normally, the valve clearance is too small or the valve is not closed tightly due to wear and carbon deposition (which is common in classic cars), and the spark plug is not good.
