problem with installation of Givi Screen

I finally received my Givi screen  ( DT214) and installed yesterday.  Even though I bought a manual I had to go back to the forum for information relating to the removal of panels. The manual only shows the location of the screws, bolts and rivets, but not the most important information: which way to move the panels to disengage the tabs without breaking them off. The installation is pretty straight forward, even with the metal bracket for the kit provided.  
The odd thing is: I can turn the steering to the left full lock with 20mm clearance from the right hand mirror to the screen, but when I turn the steering to the right, the left mirror will hit the screen before full lock. Both mirrors are installed at exactly the same angle.

Not the same topic, but whilst I was at it I also changed the coolant and with the best effort could only put 1.8 litres of coolant back into the system including filling the overflow reservoir to the correct level. I drained it on the side stand as as per forum advice filled it on the side stand and then checked on the center stand. I tried to bleed air pocket and have been for some rides since. I cannot get any more coolant into the system and I am a fair bit short of the amount described in the Honda manual. https://2img.net/i/fa/i/smiles/confused.png

I have also fitted my new 55l Givi Box and it's looking good in a matching silver.

You could try loosening the left brake clamp and slightly rotate it back a little then check for clearance when you the the handlebars. If that gives you enough clearance then tighten the clamp back up and bob's your uncle.
