2. Controlling the Flow of Energy

Beyond protection, the fuel valve controls the flow of fuel from the tank to the engine. Thanks to this valve, the motorcycle engine can run smoothly and efficiently. According to expert Robert Miller in his book “Understanding Motorcycle Engines,” the fuel valve acts as a “conductor,” regulating the energy flow for optimal performance.

Common Questions About Motorcycle Fuel Valves

1. Types of Motorcycle Fuel Valves

There are two common types of motorcycle fuel valves:
