Yamaha (and other manufactuerers) does this a lot. They will update parts whenever they find a potential weak point and issue a new part number. If you try to order the old part number you will automatically get the updated part with the new part number. That is how they keep the faulty parts from getting back into circulation. The down side is the origional questionable parts are left in service on the bikes until they fail. Only if there is a risk of personal injury or death (or really bad publicity) will the manufacturers issue a recall. If people were getting hurt on their 03 WR's, instead of just inconviencenced, there would have definately been a recall to update the woodruff/starter clutch parts. As it is, I'm glad they did at least cover the woodruff repair (twice) on my bike. Just my .02

Part numbers would be handy if you got them. On yamaha's website, you can look up the part numbers on there part's drawings. Click the link below, then select "Parts & Service" and then the "Parts Catalog".

where is GYRT ?
Never heard of GYRT, but if you talking about GYT-R, it is a company that designs and produces aftermarket parts for Yamaha. For Example: a GYT-R muffler insert, GYT-R guards, and skidplates. The only place that I know that you can buy GYT-R products is through your Yamaha dealer.

Well i am from norway, and i bought a jused wr-03. On my 10-11 trip, my bolts that hold the starter clutch loosen up and cut off. I had to buy a new flywheel, stator and starter clutch. My org bolt was 13mm, replaced with 16mm the parts cost 590$, in norway. Earlier owner(son of a Yamaha dealer) said that i was very unlucky, [@#$%&*!]!! The father could not get me the parts for his own cost.. crap. I told about the woodruff key problems that i read about on this forum, and they ment that it is`nt a problem!!!
Sorry for my bad english
loctite is my friend

its a shame that you can spend what these bike cost and have to re-enginer them to make them reliable. that could be a under statement.
Your situation is a very rare occurance. There are far more of these bikes out there that have never had a problem (woodruff key or anything else) than have. The woodruff key was the most common failure with these bikes and it still is only a small percentage that has failed. I had a loose primary gear nut on my bike. But with over 3000 miles on it that has been the only problem. I would call that very reliable. The problem with the bolts backing off in the flywheel is probably a case of incorrect assembly at the factory. When you manufacture something in the kind of numbers that the WR 450 was produced you are going to have a small amount of "scrap". Yamaha was unwilling to do anything about the woodruff key issue so I doubt they are going to even think twice about an even rarer problem.
Just fix it and ride it.

lowedog youve been lucky and i hope others out there have the same luck as you. as for a few of us, at least me i will think twice be fore purchasing a new blue bike. how do i fix my bike? do you disasemble the entire engine and clean out the fillings from the stator/and bolts , or just put in new stator and related bolts? this is not the only yamaha i own nor the only motor cycle. its just one i my hairem thats sick.
I don't think luck has anything to do with it. All the other brands have had their share of problems too. Want to go red? Be prepared to replace valves once a year on the CRF.
As far as fixing it, I would replace the broken parts and change the oil a few times with some cheap stuff by just starting it and letting it idle. This should flush the motor out pretty good. A magnetic drain plug would be a good idea.
Then I would ride that sucker and not think twice about it.
