Sounds like rev limiter at half throttle ttr90
I have just worked on a 2003 ttr90 for a friend and had a similar problem. when I got the bike it had set up for a few years so the fuel system was wrecked. after a thorough cleaning the bike would run fine up to about 3500rpm. then it would cut out much like a rev limiter. it was very consistant and I read some forums but none said anything about a rev limiter. I had also installed a carb kit. I decided to remove the carb and try again. I figured it was lacking fuel in the upper rpms so I raised the throttle cylinder needle as high as it would go. there are 3 notches to set it. the factory setting was in the middle. after I raised the needle it ran like new and turned through the rpm range perfectly. hope this helps someone.
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.
