This is a problem more for mud riders than the west coast duners. Everytime I ride thru deep mud I stop and check the area where the rear bottom a arm mounts to the hub. It’s like a pocket and collects mud. Many times I have removed small sticks and rocks. Always in fear that they will puncture rear boot. The 800 has a different design so it’s not a problem for them. Anybody come up with a solution for keeping crap out of there. I will post some pics next time out.
