Where is the ninja carburetor?
It is connected with the engine through the intake pipe, and the other end of the carburetor is connected with the fuel tank through the 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.
Carburetors are divided into simple carburetors and complex carburetors. Carburetors can also be divided into downward suction type and horizontal suction type. According to the type of throttle, carburetor can be divided into rotary type and lifting type. The rotary throttle valve is a disc-shaped throttle valve, which rotates around the axis between the carburetor throat and the intake pipe to change the flow area of the intake pipe.
