I still get the occasional go on a k6 off a mate who runs one, I'd love one in the garage for the odd go, but there's something that doesn't quite agree with my shoulder blades after a couple of hours, probably a minor difference in rake/trail or my general posture on it, but I can't manage a pain free day on it. Stocking engine on it though, and great noise even on standard cans but phenomenal with yoshi's fitted. Rode a k8 last year and didn't rate it anywhere near as good.
