What AGM battery are you guys running in a CB500/550?
Stock battery is a YB12A-A. When I look at the AGM batteries at the parts store, nothing seems to be an exact match or cross reference. Even Google turns up little (and lots of hits for small, under tail batteries, etc).
My VF500 uses the same battery and I'd love to find and AGM that swaps over or at least has similar dimensions.
