Has anyone else had this issue in north america i'm pretty disappointed with yamaha's customer service. My 2003 R6 had been having throttle problems it had become unstable and would cut on me. I had it in to two different shops to have it checked out and the finally figured out it was the tps sensore. Now it's on back order so what i'm asking is does anyone know of this being a problem that yamaha is ignoring and should be recalling?
