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.

Are you wanting the size of the hex bolt head or the thread size and bolt length? Most oil pan plug bolts are either 17mm (5/8th socket) or 19mm (3/4" socket) bolt heads.

1. 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.
2. 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.
3. 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.
4. 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.

Yes I did, I did tell you it was 1965! Easy way to check, remove a bulb and see what is written on it. It is likely to be 12 volt. https://www.google.com/search?q=Yamaha+YL1+Y33+replacement+battery ..

1965 is the year. It is a Yamaha Twinjet 100.

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:

1. Inspect the exhaust system: Make sure there are no holes, leaks, or loose connections in the exhaust system. Fix any issues if found.
2. 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.
3. 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.
4. 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.
5. 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.
6. If the backfiring persists, it is recommended to consult a motorcycle mechanic or Yamaha dealership for further diagnosis and assistance.
