Well I finally fixed my OEM bags.
After looking at the problem, which was the spacing distance from the latch to the lower pegs the case fits on. Mine would come off with no key and a med pull outward on the case handle.
Got the famous JB weld and put about 1/4 inch layer on the bottom of the well of the bag where it attaches to the pegs, so as to shorten the spacing.
Tried the bag and I put too much in so I scrape a little off at a time until I had a perfect fit. The fit was judged by when the case locked on, but I could not tug the bag off without the key.
Took her for a 350 mile spin yesterday and some short triple digits and all is well.
