I have a set of Showa FVQ shocks from a twin cam or maybe cbx, and a set of Showa VHD shocks that I removed from an 81 cb750. I like the VHD's on my K0. Is either shock even marginally better than any other stock Honda shock? I do see pages on rebuilding the FVQ but maybe that's because they came on a cbx rather than that they are a great shock.
