999 Fuel Pump Wont Stop Priming

Discussion in '749 / 999' started by RC1, Oct 12, 2025 at 9:41 PM.

  1. Got back from short spin and turned bike off and pump still priming. Had to disconnect harness underneath the tank to make it stop. Each time i reconnect the harness it starts up again.

    Any ideas on what the problem is and how to fix it?
