Using a torch and Kroil I managed to get one caliper cap nut off. The other one will not budge. The bike sat for 20 years and during that time brake fluid leaked out and dripped down the caliper and onto the alloy wheel, corroding it. I can imagine what it did to the cap nut. Looks like I'll either have to remove the forks and/or get a lift, drill through the cap nut and try the largest easy out I can find. The bike is so low to the ground I can't easily see what I'm doing.

On another note, I do not have an ignition key for the bike. I'd like to remove the fairing to make access to the headlight and lock easier. I removed the turn signals but do not want to bend the fairing over the signal posts. Any ideas about how to remove the fairing without damaging it? Many thanks.
