I added a quick detach luggage rack to the old 99 EG and, like you, found out it would not support the back 1/3 of my tour bag. I tried several things but found that a legth of the vinyl covered shelving (by Closet Maid I think) with the curved edges on both sides fit over my rack snuggly. I used some short pieces of velcro strips to attach the piece to my rack and it worked well. Not the most attractive since the color is white but I remove it at my destination. The coating kept it from scratching my chrome rack. I will add a word of caution regarding the color...DO NOT attempt to paint it, it turns into a very sticky mess. I do believe one of the catalogues sells a hard plastic platform that can be attached but can't remember where I saw it. Good luck in your search.
Have you thought about stiffening your bag? I made a cardboard liner for mine and used it on one trip, it worked fine. Since then I have replaced the cardboard with a sheet of vinyl from a shower surround.
Try a piece of wood. I used to attach a piece of plywood to my luggage rack to enlarge the surface area for larger bags. Cut the wood to the size you want then drill a few holes in it and put zip ties thru the holes to attach to the OEM rack. It works great, is cheap, and is light weight.
You are on the right road. A soft bag mounted on a support that attaches firmly to the rear rack is the best bike luggage that I have ever used. The carrying capacity of my Sportster is maxed out--don't think any additional cargo would be safe. When empty, the bag folds and locks down to about an inch thick. And, the whole shebang comes off the bike in about a minute.
I made a rack out of flat iron to the size I needed. It bolts to the sissy bar and the license plate bracket. Goes on and off in about 2 minute's and only cost $6.00 to make.
Thanks everyone. I may go with the plywood idea and since my rack is black I can paint it.
3/8" works well...not too thick, not too thin. If you want to get fancy add some 1x2" trim around the edges to help seal the exposed ply and create a ledge. Or put a piece of black marine carpet on the top side to help reduce slipage.
I took some aluminum tube and made a frame just larger than my luggage rack and a few inches longer. I took some aluminum plate and had it welded on the top of the frame. Gorilla glued some rubber (bought a heavy duty 48" truck mudflap-very thick)to the top. Drilled 4 holes and ran 4 1/4" ss bolts with fender washers and locknuts. The I ran some of that reflective red tape around the edge to give me better nighttime visibility. Very lightweight, easy to r & r and strong.
