I have owned my 06 wr 450 since November 06 and this past weekend my starter was making this awful squealing noise and sometimes would not turn the engine. I had to resort to kicking it. Other wise the bike ran perfectly find and no other issues, only when using the "magic button". So I go to the dealer where I bought it and asked the shop tech if he had seen this before. I showed him a video I took on my cell phone and as soon as he heard it he picked it out right away that it was the starter clutch slipping. He was saying that he had not seen the wr's have any problems, but the older raptors ate through them like crazy. I am wondering if anyone else has had this happen to them. I am not hard on my bike at all, I baby it. Oil change after every 2-3 weekend rides and it feels like i clean the air filter every damn day, use full synthetic 15w50 silkolene, and keep it pretty much tip top.
