I guess the main objection of some people to a cafe GL stems from the fact that it starts as a super bike, anyway. Can easily do 120+ stock or with all of the fiberglass added. And, upon introduction it was almost instantly seen as an "old man's bike". I saw them that way myself as a 20-something back then, who rode an RD400 and Penton 125 set up for flat tracking. Cafe racers were a little "new" in the circles I was in (and underwater half of every year), and I found them very cool. I had put 400 Honda bars on my RD that resembled today's Eurobars, but narrower.
Well, today I AM an old man, put 11000 miles a year on a GL1800, and the GL1000 seems like the right project for me to turn cafe. True 1940s/50s England cafe? NO! 2013 East Tennessee cafe? Heck YES! The frames were designed solid by the Honda race bike designers. Mine has a '78 frame with a '75 motor, so I get the hottest engine and get to use creativity to make the Comstars look good. The frame easily cleans up, but you have to be creative hiding the four (two double) coils and other gadgetry. Now, some may say it is best to strip the extra gauges, but being a bull-geek (I teach cyclotrons), they just have a draw for me.
The big challenge I see for the OP is to make sure all of the extras work properly, which requires careful service and faithful maintenance of the wiring harness. I've considered swapping all of the connectors on mine for more modern connectors, but will keep the older style for this one. And the four carbs with 7 jets each are real fun
Wrong to cafe a GoldWing? NO! But, it does start out as a faster, better handling bike than most HDs. Does that make it cheating?
