About a couple year back I had the indexer return spring brake -with the parts kit on hand I was up and loading in a short time.  Tonight I had the Case Insert Spring give up on me , yet I'm up and loading do to the spare parts kit I ordered so many moons ago.  After completing my loading session I reorder my second repair kit. Which brings me to my main point. The XL650 when properly adjusted will produce ammo until your arm gives out! . Mike I do not blame you for the springs giving up after I've compressed and stretched them 15,000 + times . SO would you consider it possible that in the future you could put together a spring replacement kit for those of us that are well stocked up with the other parts...  Please ..
