Problem and solution:
Is I
wrote, my Garmin Zumo 390 with the Touratech GPS-holder and
Rugged Roads handlebar mount was not compatible with the SW-Motech Yukon 90 tankbag. I like quick-lock tankbags because the ease of refuel. I've installed the tankbag as far rear as it goes, but still the front of the bag was hitting on Zumo. I tried making about 50 mm longer triangles to RR mount, which moved the Zumo about 20 mm up, 30 front. It helped with the Zumo but not with the RR mount bolts. Bolts were still hitting on tankbag at tight turns.
I didn't like to mount the Zumo over the instruments with the
TT or
RR mount. I had the Zumo over the instruments on my previous GS, with the TT crossbar. It vibrated hard on rough roads. Hence, the screen mount broke on both bikes of
Threesome with twins guys's ATs, maybe partly pecause they had their GPS over the instruments.
So, my Zumo must be on handlebars, so that it or the mount won't hit on tankbag and the holder must be fastened so well that removing Zumo from lockable holder is not neccessary on every gas station.
After few nights of thinking I figured out the solution. I bought a pair of cheapest aluminium bar risers from the local hardware store, and L-shape aluminium bar. I cut two 130 mm pieces of the L-bar and fastened them with the bar risers (the spurs filed away) between the bar holders. Voilá.
Solution is not perfect, the ignition key is left a bit narrow behind the mount. The lover third of the Zumo is left behind the tankbag and the lowest edge of instruments is left in the shade of the Zumo. But it meets the two most critical requirements, the mount is steady and does not vibrate on rough roads and it still won't hit on tankbag.
In my mind if you have any quick lock tankbag in any brand. Be aware of buying the GPS mount for handlebar mount from Rugged Roads,
Touratech, SW-Motech etc. With them the GPS will most propably hit on tankbak in tight corners.
