So I accidentally turned the crank the wrong way on my 2005 WR450 and I think I bent the Timing Chain Guide (maybe). It makes a slight knocking noise - slight as in I didn't notice anything for sometime. Under a load it make a more prominent rattling/knocking noise.

 

Few questions:

 

Did I really bend the timing chain guide?

 

How hard is it to replace the guide?

 

How much damage am I doing ridding it?

I think you're OK, I had an '06, but really don't know. Check the WR450 forum.

How did you turn the crank the wrong way? I don't see how that could bend the timing chain guide

To replace the guide the head has to come off.

So doing some more research I'm thinking it's just time for rebuild. I've put over 4k miles on it so far this year.

I'll open it up next week and see what is making the noise. I'm betting its the connecting rod bearings.

Had the folks at fastheads.com give it the once over. Nothing was badly warn out. Everything had a small amount of wear. Just got the motor back we will see how it sounds.
