03 WR450 flywheel key, revisited....
Posted June 05, 2007 - 06:06 PM
Yesterday I got around to replacing the clutch, pulled it apart and found that NONE of the fixes have been done to this bike. The flywheel had not been loctited and the idler is still the old style.(I should have known if I payed attention to the outer cover).It had never even had the jetting change made for easier starting.Sooo... I installed the new one way clutch and installed the flywheel with the correct torque procedure, and loctite,rejetted and ordered the torque limiting idler, cover and bushing.
BUT, then I got to thinking. this bike has 4 years of riding under it's belt with no issues until the one way wore out(It definately had no mechanical failure , just would not hold any more) and this thing is starting great.
So the question is, how many of you 03 WR owners actually switched over to the new parts, and if you didn't , has the starter been reliable??
I am still switching to the new style parts, but it just makes me wonder after this thing lasting as long as it has.

IMO, the key to reliability of the starter (or starting) is in good jetting (and maybe a battery tender). My bike started perfectly all weekend.

I wonder how wide spread the starter problem actually was??
I agree though that I will be installing the other parts for piece of mind, my luck is not as good as the previous owners.
BUT, I would like to know how many guys out there have not done the fix, and how many hours they have on the old parts. I am starting to think it was a hit or miss issue.

I would have done it anyways because I don't like the idea of riding way into the back country knowing there is a design flaw.
Also, some the the guys had some more serious damage due to that starter clutch not being there. The key was the weak link in the chain. Locktite it, and something else will break. Like cases. Suggest that you do the upgrade.
