The motorcycle won't get on the accelerator.

This situation is probably caused by improper mixing of carburetor. The carburetor mixture adjusting screw is under the left accelerator cable of the carburetor, and some of them will be plugged with small black rubber. You can see it when you take it off. The mixed gas screw goes out with rich mixed gas, which usually comes out for one and a half to two and a half turns after being screwed to the bottom, which should be adjusted according to the vehicle test. The genuine price of this Mikuni carburetor is 400-500 yuan. In addition, check whether the air intake system and valves of your car are leaking.
