O.k. I have been reading the threads and still don't understand what the woodruff key is. Is it just for the starter? If it goes out can't you just kick start it? I am going to go look at an 03 wr450 at a dealer tomorrow and need to know what to look for. Any help would be greatly appreciated. Thanks, Dan

I believe the woodruff key is for the stator or its equivalent. So, if it shears off, you will get no spark generated no matter how you try to start it.

Go to this web site link and print off the instructions and order the parts to upgrde your 03 starter design to 04 design. This is critical to avoid expensive engine case cracks, gear breaks, and the woodruf key failure you mentioned.

Note that the instructions have been changed to allow you to keep the side cover by ordering a bushing and pressing it into the old side cover. :applause:

I just did mine last night. If you buy the bike make them throw in the parts for free. The dealer cost is less than $100 for the parts. it cost me $168.68 out he door.

I know this has been covered before, but is the starter conversion still needed if the dealer did the woodruff key fix before I picked up the bike new back in 2003?

Yes you still need to upgrade. the woodruff super lap and loctite bandaid fix actually can make the failure more severe with damage to the engine and cases! Brilliant fix recommendation by Yamaha!!!!!!! :applause: :ride: :p :p :lol: :p :p :lol: :p :p ;) :p :p ;)
