I can take some photos if needed but there very simple, 4 straps at the front. One for the top (handlebars / forks area) and 2 for the rear.
Take your seat off and lay the tank cover over the tank and line up the tank logos with the windows.
The two rear straps are the only pain's (but there not that bad!)
I've threaded my ones as follows:
Left side goes over and under air intake tube and round the back of the frame tubing and back up to snap connector on cover.
Right side goes over and under plastic cover, again round the back of the frame up to the right side snap connector.
They are pretty short but do fit nicely.
Rolling the strap helps it curve round the tubing or if you've got a pair of tweezers or similar to grab the strap as you insert it behind the frame tube.
All others are just slidelock buckles which are easy. Then its just a matter of tidying up the straps!
If you need access to the battery / fuel connectors you can get away with just undoing the rear straps
Been out in all weathers all over winter and I've not had any problems with moisture etc..
The original BMW tank bag fits also with a bit of dual lock tape -
Hope this helps!
