9 posts in this topic

Im asking cause i need a few parts for my 2003 wr450, wondering if the left hand crankcase cover (stator side) is the same as well as the 04 starter damper assembly and starter.. i found some good used yfz450 parts for dirt cheap.. 

 

nevermind,  please delete this topic

I'm also wondering the same thing. Did you ever figure out if the parts were compatible?

WR's use a different crank, stator, and cover.

To change one you must change them all.

I have an 09 wr450f. I need the damper assembly and it's so expensive! But I found a bunch on eBay for a yfz450 for real cheap. So your saying it won't fit?

Remember he's talking about the four wheeler electric start YFZ. 

Check part numbers for a exact fit.

I don't know part numbers well enough to know what that means. You could pm greyracer maybe he knows.

I know the starter motor is different enough that it will not work on the WR.   I can't remember if the splines are the same or

different but if they are different that could account for the different damper in the quad versus the WR.

If I had to make a bet I would bet on it not working...   look for one from a WR
