How many of you with a WR450 have not had a Woodruf key failure? I have about 800 miles on mine and no problems yet. I ride with my kids most of the time so I use the e-start a lot. I want to know if there are more of us then the ones with problems. I still want to know if the 04 parts are going to fit. I think we would all go for the retrofit if it works. I love my e-start and do not want to give it up.
