The swingarm came out without drama a couple of days ago. It turns out that I was just being paranoid. The bearing and UJ look fine, but I'll replace the UJ anyway. I might order a replacement gaiter as well as long as they're not too expensive, seeing as the current one has a couple of tiny splits. I'll also slap on some Hammerite once I get the swingarm degreased and the worst of the rust off. Shit. It only just hit me: I'm down to one roadworthy bike ATM. I feel naked.
