2001 Yamaha Drag Star Four - Answered Questions & Fixed issues
Electrical trouble
If all the fuses turn out good especially the main fuse then you might want to check your starter solenoid.
Try jumping the two leads on the solenoid if the bike starts then most likely the solenoid is bad.
If it doesn't start then it could be two other things.
1- your Ignitions might be shoot. tell tail signs. Bike cutting out during the ride and bike loses power when you hit the starter button but power returns when you turn the key off then back on.
2- The Rectifier might be gone. The rectifier will cause many different problem that might have you chasing carb problems, to the bike won't start at all with no cranking

Hi
That's a fuelling problem
Sounds like she has been laid up for a while -
If more than 5 or6 months then you'll have to drain & replace the fuel from both the tank & carbs
If over a year then you may need to strip the carbs
It could just be sticky floats - try adding a carb cleaner to your fuel
Ride Safe

2005 Yamaha v star 650 losing power
What Exactly does the bike do when it 'loses power'? This will give clues as to where the issue could be. When was the last time the bike was given a major service? Sometimes it can be as simple as a dirty fuel/air filter or an old/worn or dirty spark plug.

1995 Yamaha Virago 535. It runs good for about 7 miles then starts backfiring?
- Fuel System Issues:
- Check the fuel system for clogs, such as a dirty fuel filter or carburetor jets.
- Ensure that the fuel tank and fuel lines are clean and free from debris.
- Consider adding a fuel system cleaner to help clean out any deposits.
- Ignition System Problems:
- Inspect the spark plugs for fouling, wear, or improper gap.
- Check the ignition timing to make sure it's set correctly.
- Inspect the ignition coils and wiring for any loose connections or damage.
- Air Intake and Exhaust Issues:
- Examine the air filter for clogs or dirt that may restrict airflow.
- Inspect the exhaust system for any leaks or blockages.
- Vacuum Leaks:
- Check for vacuum leaks in hoses, gaskets, or intake boots. A vacuum leak can cause an improper air-fuel mixture, leading to backfiring.

How to plug the ais on a 2001 Yamaha vstar 650
If your Yamaha Vstar 650 is backfiring when decelerating, it could be due to a lean fuel mixture or an air leak. One solution is to adjust the air/fuel mixture screw on the carburetor, but before doing that, it's recommended to check and address the following:
- Inspect the exhaust system: Make sure there are no holes, leaks, or loose connections in the exhaust system. Fix any issues if found.
- Check for air leaks: Inspect the intake manifold and carburetor boot for any cracks, loose connections, or air leaks. If you find any, fix them and ensure a tight seal.
- Clean or replace the air filter: A dirty or clogged air filter can affect the air/fuel mixture. Clean or replace the air filter if necessary.
- Check carburetor jets: If the bike has been sitting for a while or the carburetor hasn't been cleaned in a long time, there might be debris or clogs in the jets. Remove and clean the carburetor jets.
- Adjust the air/fuel mixture: Locate the air/fuel mixture screw on the side of the carburetor. Gradually turn it clockwise or counterclockwise (usually clockwise) until the backfiring reduces or stops. Start with small adjustments, and make note of the screw's original position in case you need to revert the changes.
- If the backfiring persists, it is recommended to consult a motorcycle mechanic or Yamaha dealership for further diagnosis and assistance.
