My 03 WR450F had 230 miles on it with two 2 hour hare scrambles under its belt with no issues. I heard about the fuss on the woodruff key and since the service bulletin came out, I decided to take it to my dealer to have it serviced. I got it back and went to ride it this weekend. 6 miles out down in a creek bed I stalled it from being in too high of a gear. I went to start it and the starter motor just spun. I knew immediately what was wrong and pushed the bike out. Now, was this a coincident? or did the shop make my bike worse? Since they are closed on Monday's I will take it in tomorrow. This is disappointing because I had no failure before I took it to them. Now it has failed and could have possibly damaged something else. But this does show that the fix doesn't work. Either that the shop screwed up. They claim to have lapped it and followed the service bulleting procedures.
