Putting a tourer up on that jack adapter and THEN removing the bags and rear wheel WILL cause the bike to tilt forward to rest on the front wheel.
I had strapped the bike to the jack itself so was able to apply a little pressure to the back of the bike and then slid some wood under the front wheel.
I remove the bags when I work on my rear wheel too. And take off the shocks and rear fender section.
I never raise my bike more than an inch or two, it is always stable... I don't even lift it to the first lock,
I jamb a board in the lift sissors... note the slip of paper under the headers - if you're not careful,
you'll be lifting by the headers... I put a board perpendicular to the lift forks now, and miss the
headers by a mile.

This turnbuckle comes in way handy too!
