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.

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.

If you've verified you have good spark on the plugs while turning over the engine with starter.... And if the plugs are wet with fuel after attempting to start the bike, then it is very likely that the timing is badly off. Checking the timing to specs. In the manual.
