More wirewheeling! The lower triple tree, a break caliper and the rear master cylinder's body. The clip that holds the rear master together is rusted in there badly, I broke one end off and the other won't budge.
This pore rear hadn't been serviced in a long, looooong time when I took it off the bike, the fluid had turned to a chunky/grainy white substance and the rust was pretty bad in there too, there was even a lot of deep pitting in some of the aluminum around the dust seal.
