Anybody know where this washer goes?

rebuilt the top end and replaced the clutch on my '02 and this was left over...... oops! having problems with compression and hoping this is the culprit. Thanks for any help!


Not sure because the pic isnt totally clear but it looks like the washer that goes under the valve cover bolts. Had one fall off on me one time and first time rode it oil went everywhere.

Thanks but its not that one. we have all of those. this one is sort of bluish and on the thick side for a washer. sorry for the blurry picture.

another pic - hope its better


Looks like one of the thick grade 8 washers used on the large 10mm head bolts/nuts???????

I second what MED says. Looks like one of the head bolt washers. It's really easy to check, just pull the valve cover and look at each of the four head nuts to see if one is missing.

Hmm I hope you would have noticed a missing head bolt washer when you put the top end back on. Are you sure it came off the bike?

now you guys got me wondering the same thing.... it was in the box with the rest of the parts from the teardown and it wasnt a old box. its not a head bolt as we have removed the head twice (trying to figure out where the compression went) and couldnt have forgotten it both times.

any chance it is from the clutch that we replaced also?

Looks like the washer the goes on the crank right behind the flywheel nut. Maybe you forgot it on another bike...

i second spinyard's guess. it lookes like the washer that goes under the flywheel nut.

      I need recommendations on Honda dealers with good Mechanics in Western Washington. I am in Puyallup but will drive for peace of mind. I have never had a dealer do major work on any of my dirt bikes. But long story short I am on a 15 CRF450R and it needs the 5th gear recall done. Any and all info is much appreciated!

      I have a 2005 CRF450R with a Trail Tech fan kit installed. I need a little bit larger tank and would like to know if anyone has an aftermarket tank that fits with the fan kit.
      I dont need a monster 4 gallon, just maybe a 2.4 or 2.7 from IMS would do fine.  I talked with both the tank vendor and Trail Tech and neither could give me any answers.
      Thanks guys.

      So I emailed Factory Connection today to see what spring rate I need for the rear as I’m about 6’2” 220 lbs without gear. I also asked for a baseline front fork PSI to start at. This is what I received:
      The spring series we made for your bike is limited when it comes to larger/stiffer rates.  
      The spring rate you need is 5.9/6.0 range. We don’t sell that over the counter as it requires special installation process.  So we can’t sell the spring “over the counter”.  It would have to be installed at our shop.  
      Fork PSI I would recommend:
      Inner 160 psi
      Outer 11 psi
      Balance 160 psi
      Are they blowing smoke up my ass? What kind of ‘special installation’ could a spring take? I’ve changed and removed them before but not on a 16’ CRF before.
      Also, aren’t those psi settings for the Kawasaki KYB? I don’t think the psf2 have inner/outer/balance do they? Maybe he was having a bad day...or maybe I’m an idiot. FC’s website list there spring as ALS-0059. Can I not just order this spring and install it to set my sag correctly? Help?
