Why does the motorcycle throttle not increase and make a popping sound?

[LeFelix]

The reasons why the motorcycle throttle does not increase and makes a popping sound are as follows: 1. Poor quality gasoline; 2. The carburetor is too dirty, and the low oil level in the carburetor float chamber causes insufficient fuel supply from the carburetor, resulting in engine knocking; 3. Excessive clearance between the cylinder liner and piston in the engine causes knocking under load. The solutions for the motorcycle throttle not increasing and making a popping sound are as follows: 1. Check if the spark plug is faulty and if there is any interruption in the high-voltage electricity, and inspect whether the air filter and carburetor are clogged; 3. Thoroughly clean the carburetor and check the carburetor's mixture ratio, needle valve, and choke.
