How Does the Bike Petrol Reserve Work? Understanding “On,” “Off,” and “Reserve”

If you’re a bike rider, you’ve probably noticed the fuel knob on your bike with three options: “On,” “Off,” and “Reserve.” Many riders aren’t sure what these settings mean or how to use them correctly. Don’t worry—I’ll explain everything in simple terms.

What Is the Petrol Reserve System?

The petrol reserve system is a backup fuel supply in your bike. When your tank is almost empty, the reserve system holds an extra 1 to 2 liters of petrol so you can reach the nearest petrol pump. It’s a useful feature that ensures you won’t get stranded when you run out of fuel.

What Do “On,” “Off,” and “Reserve” Mean?

Here’s what each setting on the fuel knob does:

1. On

• In the “On” position, petrol flows from the main tank to the engine.
• Use this for everyday riding when your tank has enough fuel.

2. Reserve

• Switch to “Reserve” when your bike runs out of petrol in the main tank.
• This setting lets you access the extra fuel in the reserve tank to keep your bike running.

3. Off

• The “Off” position stops the fuel flow completely.
• Use this setting when you park your bike for a long time to avoid leaks.

How to Use the Petrol Reserve System?

Using the reserve system is simple:

1. Start with “On”:
   Keep the knob on “On” while riding. It uses petrol from the main tank.
2. Switch to “Reserve” if Needed:
   If your bike starts sputtering or stops due to low fuel, turn the knob to “Reserve” to use the backup fuel.
3. Turn “Off” When Parking:
   When you park your bike for an extended time, switch the knob to “Off” to prevent fuel leaks or wastage.

Tips to Avoid Running Out of Fuel

Here are a few simple tips to keep your bike running smoothly without worrying about running out of petrol:

• Refill Early: Don’t wait for the tank to hit reserve—refill when it’s about 25% full.
• Monitor Mileage: Keep track of your bike’s mileage and fuel usage.
• Service Regularly: A well-maintained bike uses fuel efficiently. Check out our Periodic Service to keep your bike in top shape.

Common Problems With the Reserve System

Sometimes, the reserve system can cause issues. Here are some common problems and how to fix them:

1. Blocked Fuel Lines:
   Dust or dirt can clog the fuel lines, stopping petrol from flowing. Regular cleaning can solve this.
2. Fuel Leaks:
   If you smell petrol or notice a sudden drop in fuel, there might be a leak. Get it fixed immediately.
3. Stiff Fuel Knob:
   If the knob is hard to turn, it might need lubrication during servicing.
