Looking over the parts in my HOG D1 service kit, I found this o-ring. What the heck is with the little protuberances?! I have never seen anything like that, in my other service kits or anywhere else. I only service regs about once a year, and I don't deal with o-rings in my daily life, so I have no sense of how common this kind of defect is--or now that I think about it, the broader question of how common defective parts are in reg service kits. This is a question I would like to ask HOG/Edge, but what kind of quality control does this reflect? This defect is clear as can be.
