Slightly annoyed to find these two shims in my box of bits created when I stripped my front and rear CB500 K1 wheels right down for a hub reline and rebuild. I have no idea where they should go. External diameter 30mm, internal diameter 23mm.
I stripped and refurbished the speedo drive too and am wondering if that's where they came from but having looked at Trigger's photo at the bottom of this post:
http://www.sohc.co.uk/index.php/topic,20419.30.html there is only one shim behind the circlip and my speedo drive has gone back together just fine.
Anyone got any ideas? I can't see anything in the part list.
