Bought my 03 WR450 Oct 5th, asked them about Woodruff key status, they said this forum overexagerates, and there is no problem. I asked them to check just to be sure. The manager told me the key was showing "signs of wear", and needed to be replaced. I went on a 30 mile loop sunday, about 7 miles in, small backfire....then a whole lot of pushing. Starter motor just spins (doesn't turn over the motor). Unable to kick. Sounds like the key sheared, huh? this will be the 3'd key in aprox 50 miles. I just got off the phone with customer service, and they assured me "they won't replace the unit". In turn i assure them i won't pay for the motorcycle (yamaha credit). This is such BS. i don't know what to do.
