Priming the fuel pump on a Honda XR190 is a simple, yet important, part of the starting process. The purpose of priming the fuel pump is to build up the correct pressure in the fuel lines, ensuring that the engine gets a steady and sufficient supply of fuel as soon as you hit the starter button. Let’s look at how easy this is.
1. Insert the key and turn it to the “ON” position. Don’t press the starter button yet.
2. Listen for a humming or whining sound. This sound comes from the fuel tank and indicates that the electric fuel pump is running.
3. Wait for the sound to stop. The pump runs for a few seconds (usually 2-3 seconds) to pressurize the fuel system. Once it has reached the required pressure, it will automatically shut off, and the sound will stop.
4. Once the sound stops, you are ready to start the engine. Press the starter button and the engine should fire up without issue.

Priming the fuel pump is a crucial step to ensure a smooth and easy start every time. The process builds up the correct pressure in the fuel lines, guaranteeing that the engine receives a steady and sufficient supply of fuel as soon as you hit the starter button.
If you don’t prime the engine, starting may be rough and difficult and you may also stall after driving away.
No, in Vietnam the Honda XR190L is a fuel injected bike, whereas the XR150L has a carburettor. This means that the 190 is easier to start and will likely have better performance and fuel economy. The 150 can be more difficult to start and you may need to use choke (link to video).
No, you should not touch the throttle while starting the engine. The fuel injection system is designed to automatically provide the correct fuel-air mixture, so manipulating the throttle can disrupt this process and make the bike harder to start.
Yes, it is a recommended best practice to do this every time you start the motorcycle, especially when it has been sitting for a while. It’s a quick and simple step that ensures the bike starts reliably and can help prevent potential issues with the fuel system over time.
Not at all. The process is extremely simple and only takes a few seconds. Just remember these three steps: turn the key to “ON,” listen for the humming sound, wait for it to stop, and then press the starter button. It will quickly become second nature.
Mastering this simple Honda XR190L fuel pump priming step guarantees a smooth start for your Vietnam adventure. This quick, crucial process ensures your touring motorcycle is always ready to ride, no matter where your journey takes you.
