I was following TwoWheelObsession's excellent YouTube tutorial on lubing the shaft drive, but when I was putting the rear wheel back on, I couldn't find the washer that goes between the brake and the swing arm. I'm thinking it's somehow fused to the brake actually. I forgot to take a picture of it with the brake off, I can if I need to, but this is what it looks like now. There's a space there that exposes some of the axle, but it looks like there's a similar space on the bike in the video. Thoughts? 1st Gen '03
