Nigel, is your aftemarket shock set to increase ride height? When I had mine dialed up, the chambers were jammed against the swingarm pretty tight unless I sat on the bike, and when I dialed the shock length down to the same or just slightly longer than stock, I had okay (2mm) clearance. Wondering if it is worth further "jiggling" because I'd like to get some of that ride height back without grinding any parts the way Paul suggested or flattening the chambers. Cheers.
