Where is the motorcycle carburetor?

It depends on what kind of car you are. The carburetor is close to the engine cylinder and connected with the engine through the intake pipe. The other end of the carburetor is connected with the oil tank through an oil pipe. If it's a straddle bike, it's under the fuel tank and behind the engine. If it is bent down, it is blocked by the fender on the engine, but it can be seen from the hole on the left or right side of the fender. If it is a scooter, you need to remove the cargo box under the cushion to see the carburetor.

This noise and inability to refuel may be due to the blockage of carburetor, water in gasoline, weak high-voltage electricity or air filtration problems. I'm afraid I can't fix it myself. Go to the mechanic as soon as possible.
