That for the eBay idea. What soft bags are you using and how do they deal with the rear turn signals with those racks ?
Ebay is the KLRista's friend. Great source for used parts to fix everything you break. I use a set of saddlebags I bought off ebay several years ago called Moto Pak. I got a good deal on them and am very happy with them but I can no longer find them on ebay.
Edit: I found a link to the bag I have. http://motopakluggage.com/gts90.html
I paid about $65 shipped back when they would sell one bag a week on ebay. I think they are a fairly new company and were selling them cheap just to get their product out there. They must have stopped selling on ebay but you can get them through some retailers.
