Part Identification Help Needed

[reellentless]

Hello All,   I am back for some help from a great forum.  I was on here years ago (7-8 years ago) when I rode a lot, but then I took a second job and the bike sits a lot.    Anyway I have been riding the bike (2005 WR450)  just enough to keep good fuel and keep it running up until  the last two years.   Needless to say I had to take the sub frame loose to get the carb off.  Now it is running and time to put back together.  (Garage running....as we have a foot of snow on the ground)  I had the sub frame loose and not everything back on or tight while I test ran it and adjusted the carb.    I saw I stepped on this part as it had vibrated off.   Can someone help me as to where it belongs?   I'm thinking some place on sub frame due to oval hole for adjustment.

Just bumping it up one time to see if anyone recognizes it.

I have a 2010 YZ450F, it has the same washer/ tab thing on the right hand, forward, lower engine mount. I have no idea what they are for. I don't remember seeing one on my WR but it had been through several different owners.

SAKs....I think you nailed it....took off my Acerbis 6.6 to put on the 3.3 and gain some room to work. (bolts to front motor mount)   Thanks a bunch.

Actually, that looks more like the funky washer on the bolt that attaches the middle of the exhaust to the subframe.

 

I have never seen anything other than a regular flat washer on the motor mounts of the steel frame bikes.   The parts

fiche shows a washer like in the picture SAKS posted for the aluminum frame bikes but it is not present on the steel frames.

I have had my 05 apart many times and have never anything like that on my bike . 

 

Pretty sure that is not from your WR . 

 

It kind of reminds of an old car carb shaft lock washer .

Have not seen such an item from my (3) WR's

Deep Purple Bruise!  You are the man!  BAM!   Exactly the part as it was not off the motor mounts as I checked that.   I just about put it all back together but so glad I waited another day.  Will be putting it back together tomorrow, and hope for an outside ride if the weather holds another day or two and the roads clear.  Thanks a lot....this place is awesome.

Most people won't see that part because it's supposed to stay captive on the sub frame (thus the tabs). It's to keep the pipe from chafing at the aluminum mount tab.   Usually won't fall off, but....

That makes sense, but that means mine are installed wrong....
