You probably still have air in the system ... Back to bleeding ! start bleeding from the top down--banjo bolts down to bleeder--then let it sit for a few minutes and take a plastic hammer or a piece of wood and tap on banjo bolts to move air bubbles to top and bleed again.
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.

- 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.
