Question about 1999 Honda Hornet 250
Hello my 250 hornet is very sluggish at 5000 rpm when accellerating at runs very roughly when simply idling even when warm.
i am wondering what would be the most likely reason for this
Could be a carb problem or spark plug problem.

Sounds like timing but could be a carb problem

Engine stalling and rough run
issue at low speeds
This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control
