Oddjob: this is on an M. Both 125Ss are. Probably selling the blue/white one, actually. Bloke is waving £1400 at me. It needs the wheels doing to be perfect.
I got it cheap because some lummock had rebored it, done everything, spent £750 on the paint, and then forgotten to re-connect the camchain adjuster to the tensioner blade so it still rattled. He didn't know why it was making a noise, and I took a punt: I was certain that was the problem. And it was. Half an hour and one circlip later and it was running like a watch.
The red/white one is probably two grands' worth. Unrestored, 9000 miles, and utterly immaculate and original.
