Yeah, I basically just used the inner strap/bungee things to secure a DOP kit into the bike side of the pannier, above the cut for the muffler (it fit perfectly) and then stowed my handy BMW pannier liner into the outer "lid" of the pannier, securing it also, with the bungee retainer system. Fortunately, I packed rather lightly, so everything fit well. Much more in the pannier liner and it wouldn't have fit.
I have an after market (taller) windscreen on my K1200 and also a Laminar Lip. Just washed all the bugs and road grime off the the bike, and boy I'd have loved to take off the LL for cleaning- but no way, apparently. Their HD Velcro is mighty tough stuff. I tugged on it pretty hard, to the point where I feared I might break either the windscreen or the lip. It didn't even begin to budge.
Let us know how you like the peg lowering kit- I might go that route myself. I DID drag a toe on one of the tighter curves on the Cabot Trail the other day tho!

Cynthia is used to my leaning the bike over- she hangs in there really well- and never even knew I'd touched down.
When I got the bike, the PO had the seat in the lower position, being about the same height as me but with shorter legs. I moved the seat into the higher position and it transformed the ride both for me, AND my girlfriend, who is is about 5'-10 & 1/2". I couldn't figure out how to get the seat into the higher position, so I went to a local BMW dealership. One of their guys came out and showed me the trick. It's going to take some practice to get that one down pat. Moving it up made a HUGE difference for me!
