How long does the motorcycle throttle need to be cleaned?

I don't know what kind of car your car is. Generally, 600CC cars should be road sports cars. Throttle cleaning depends on the road conditions, and it is best to wash it once every 1000 km. The position of the throttle valve is generally at the rear end of the engine and in front of the intake manifold. If it's the throttle of the carburetor, it's in the carburetor directly behind the engine.
