XR650R Front sprocket install question

The front sprocket has a splined washer that goes on the outside of the sprocket. The splines on the washer don't line up with the splines on the sprocket, so when everything is tight, the sprocket actually has some free play towards and from the tranny, because the splined washer ends up riding in a groove in the sprocket shaft. Is this normal? I can't see any other way it's supposed to be, but don't remember it being like that last time I had the sprocket off (long time ago). Thanks.

Yes, that's normal. The misalignment of the washer to sprocket keeps the sprocket from coming off the shaft. There's should be no freeplay in the drive directions of the sprocket, but there will be freeplay in the direction to and from the gearbox.

OK, just figured I'd make cause I didn't remember it being like that before. Thanks for the help.

I found my splined washer lined up with the sprocket last weekend. The sprocket was, of course, trying to come off the shaft. The sprocket cover was keeping the sprocket on the shaft but it was making a lot of noise doing it.

I took the splined washer off rotated it to the second set of holes and bolted it back up. now it has the misalignment needed to make it work.

The weird part is I know how this assembly works and was sure I had assembled it so it had the missalignment to keep it from coming off. The last time I changed the primary sprocket was over a year ago. If it was misassembled it should have shown up before now! :applause:

I am going to take it back apart and inspect the sprocket and splined washer and see if there is any damage.

Very weird :ride:

I ordered a sprocket from Ironman last year that came with a washer that was drilled wrong. It aligned with the splines. Did not notice it when I put it on. I rode the bike for a couple of months before I finally noticed it. Called Ironman and they sent a washer that was drilled correctly.

Had me puzzled for a while as well...until I worked out what honda were thinking...not a bad idea eh??
