2007 WR450 Crank Issues
Posted July 15, 2008 - 05:18 PM
1- Have you ever heard of a chain tensioner failing on a bike this new?
2- What would cause the timing chain to strech?
3- Have you ever heard of a problem like this before?
4- Should I keep riding the bike? Other then the noise the bike seems to run fine.
Thanks for your help

The '08 has reduced gear lash, and so is somewhat quieter.
On the cam chain, there have been a small number of reported failures of chain tensioners that resulted in the chain becoming severely kinked at low hours. Not many.

If there is something wrong and the motor grenades you'll have to take out a second mortgage to fix it.
The aluminum WR's are noisy but if the bike suddenly starts making noises something is wrong.

I plan on taking it to anouther shop in the next couple of days to have them listen to it. There is definetly a problem though, one of my riding buddies has the same bike and it definetly does not sound the same as his.
Do you think the shop sugested I keep riding the bike until it blows up to hide the fact they screwed up? Could they have dropped a shim or something down into the crank by means of the timming chain? Man this might get dirty.
