So it’s all back together…

…and as expected the chain line clears the swingarm just fine. I had to remove about 4″ of chain but I left the slightly long rear cables intact for now. It was fun to ride around on it again… feels like it’s been a while. One or two more test rides then I’ll strip it down and start the finish. Here’s another gratuitous picture…

After some pondering I settled on fixing the chain rub by moving the rear pivot. So I dismantled the bike, cut out the pivot tube and cut a new ‘fishmouth‘ in the main boom. I clamped the back-end in place to check the fit. All seemed well so I welded it back together.
It seems to have worked. I assembled the back end and the chain line clears the swingarm completely, even when the suspension is bottomed out. I say ‘seems’ because I’ve yet to build the complete bike and test ride it. I’m reasonably confident it’ll be OK, because the suspension will never be fully compressed: the worst that could happen is occasional chain slap.
So next steps are (1) rebuild the bike and test ride it, (2) break it down again and finally (3) prep and paint.
This is dragging a bit… I’d hoped to be done by now.
