Solutions that Worked

1. Check for Clogged Fuel Vent or Line

What I Did:

Popped the gas cap off and heard a whoosh.

Outcome:

The bike stopped shutting off while riding.

Personal Experience:

I noticed a significant difference after checking the fuel vent. It seems like the vent was clogged, creating a vacuum that disrupted fuel flow.

Estimated Cost:

$0

Time Needed:

5-10 minutes

Steps:

  1. Stop the bike and turn off the engine.
  2. Open the gas cap carefully.
  3. Listen for a whooshing sound, indicating a vacuum.
  4. If heard, locate the vent line near the fuel tank.
  5. Clean the vent line using compressed air or a thin wire.

Expert Tip:

A clogged fuel vent can create a vacuum in the tank, disrupting fuel flow and causing the bike to shut off. Always check this first as it’s a simple yet commonly overlooked issue. Keep some compressed air in your toolkit for quick cleaning.

2. Check Fuel Tank Vent Line

What I Did:

Checked the fuel tank vent line and found it was kinked.

Outcome:

The bike stopped shutting off.

Personal Experience:

After straightening the kinked vent line, the bike ran smoothly without any issues.

Estimated Cost:

$0

Time Needed:

5-10 minutes

Steps:

  1. Locate the fuel tank vent line, usually near the fuel tank.
  2. Check for any kinks or blockages.
  3. Straighten the line if kinked.
  4. Use zip ties to secure the line in a straight position.

Expert Tip:

A kinked vent line can also create a vacuum in the fuel tank, leading to similar issues as a clogged vent. Make sure the line is straight and unobstructed. Use zip ties to keep the line straight and prevent future kinks.

3. Check Fuel Pump

What I Did:

Replaced the fuel pump.

Outcome:

The bike stopped shutting off.

Personal Experience:

I noticed the bike was acting weird, especially when accelerating. Replacing the fuel pump solved the issue.

Estimated Cost:

$50-$100

Time Needed:

30-60 minutes

Steps:

  1. Locate the fuel pump, usually under the fuel tank.
  2. Disconnect the battery for safety.
  3. Remove the fuel lines connected to the pump.
  4. Unbolt and remove the old pump.
  5. Install the new pump and reconnect the fuel lines.
  6. Reconnect the battery and test the bike.

Expert Tip:

A failing fuel pump can cause intermittent issues that are hard to diagnose. If you’re experiencing random shut-offs, consider checking the fuel pump. Always disconnect the battery before working on fuel-related components to prevent any sparks.

4. Rejet the Carburetor

What I Did:

Rejetted the carburetor after installing aftermarket intake and exhaust.

Outcome:

The bike stopped shutting off and stuttering.

Personal Experience:

After installing some aftermarket parts, I noticed the bike wasn’t running well. Rejetting the carburetor fixed the issue.

Estimated Cost:

$20-$50

Time Needed:

30-60 minutes

Steps:

  1. Remove the carburetor from the bike.
  2. Open the float bowl to access the jets.
  3. Replace the main and pilot jets with ones that match your setup.
  4. Clean the float bowl and other components.
  5. Reassemble and reinstall the carburetor.
  6. Test the bike to ensure proper performance.

Expert Tip:

If you’ve modified your bike, you’ll likely need to adjust the carburetor settings to maintain the proper air-fuel mixture. Failing to do so can lead to performance issues. Always test ride in a safe area after making adjustments.

Exta tips

  • Ignition System: Sometimes, the issue might not be fuel-related at all. A faulty ignition system can also cause the bike to shut off. Check the spark plugs and ignition coil.
  • Emergency Shut-off Switch: Believe it or not, some people have accidentally hit the emergency shut-off switch while riding. Make sure it’s in the ‘Run’ position.
  • Electrical Connections: Loose or corroded electrical connections can cause intermittent issues. Check all electrical connections, especially if you’ve recently worked on the bike.
