Thanks for the kind words, Red, but what little I know about Airheads I learned from just reading and asking lots of questions, mostly here. There's folks here with lots more knowledge and skills, for sure! But yeah, I've made riding friends here and still lurk here a bit, and imagine I'll either wind up with another R65 or it's slightly larger, strange older cousin, the R80ST.
But, regarding your bracket question, if it's a standard airhead plug and not the BMW Powerlet-type receptacle, does this bracket look right? It mounts on the R65 on the left side, behind the side cover, in the crook of the rear subframe.
