I'm planning on putting some new tires on my 97 this winter. Last time I did the same I noticed some slight scoring on a composite/nylon washer, wasn't bad so I put it back in with a mental note to replace next time.
I'm looking for it now and can't find it in the parts diagrams. If I recall correctly it was located on the driven flange, I see it in the service manual but not in the parts diagrams for order. I think it is identified below as "washer".

I don't see it in either the final drive or rear wheel parts diagrams. I should probably just wait until tomorrow and look again, probably right in front of me but thought I'd ask if anyone knows the p/n.
Also just felt like posting, haven't been here in a while...and while I'm here.
Weather here last Saturday was amazing for late October, near 80* and sunny. As luck would have it we had our end of the season ride planned with a couple of my brothers, some friends, my son and some of his friends. Just under 340 miles through western MA and CT.
50 years or so of riding and nothing compares to multi-generational rides.
