I've been lucky. All five have come with complete kits. At least is gives me a little warm and fuzzy feeling. I do keep my chain lubed and adjusted when I'm on the road.
Honda quality is such that I rarely need to use it. 🙂
Something is missing................The extension handle for the C spanners, coupled with the chain adjuster it makes for a maintenance strut for raising the fuel tank, apart from being essential for normal use of the C spanners.
