Well the GF keeps all her drugs ( aspirin, ibuprofen, eye drops, sun screen etc.) in the right side and we used to keep our smokes in the left but we quit so will have to find something else to put in there.
The right side door on mine had a broken hinge when I bought the bike. It stays in place as long as I don't open it. SO, it was the perfect place for relays for the MegaSquirt, Fuel Pump, and o2 sensors. (if I remember right) the left pocket is empty.
well I must say the PO of my bike used one of them for a place to hide the spare key
he first put it in a piece of tape then wrapped it in a dirty paper towel and just stuffed it under the edge under the door
that saved me some serious heartache when I had to leave it due to alt failure on my way home, when I went back with trailer to get it I forgot keys, so when I got there I was thinking,,, now what,,, then I remembered that key
needless to say it saved the day
other than that they stay empty untill we head out and wifey fills them up with stuff
