OK. I said I'd give you the weekend off. But . . .
I'm smart enough to disable the old center stand. Especially because my pipe is smooth, before they had teeth for a better lock. Lots of horror stories about the stand shooting down when the bike hit a bump.
I bought a generic, made-in-the-UK side stand. There's no way it fits with the exhaust pipe where it is. No way to get the angle right. I'm a good metal worker. Do I make an add-on sub-frame that's a bit lower to clamp on to? A better option seems to be cutting the metal between the clamp and the pivot shaft and doing an off-set weld.
I know that a few of you have figured this one out.
