Has anyone installed a Zumo 550 on the F800gs using Touratech's mount and a 1200GS crossbar? Any thoughts/comments? I can't use touratechs regular mount for a F800gs as I have HDB's top clamp which doesn't mate up and I don't want to use a ram mount. I installed it on mine after coaxing the crossbar into a curve to make the fit. This puts the clamps below the bend in the handlebars which are tapered. The clamps don't fit flush due to the taper but seem to be acceptably tight. I used my gorilla hands to try and pull it loose to know avail. Is this something I should worry about or just forget.
