Rare bird someone recognized and snapped up...might see it pop up as new member's bike.
I sold a cb550F/cb550k3-k4 tank on ebay several months ago that went to a buyer who was some shop in LA area and they were typical cut up a bike and tank, etc "cafe" sometimes but, more of brat and tracker builder given their website. They had taken some nice bikes which were good to great condition originals and hacked them up. I know you can't save them all but the originals are will be worth a lot more in a few years, if not already.
Tank I sold had old Kreem liner and needed repaint because of chips, but a good tank.
Given K's lack of compatibility with an F or '77-'78 K it would require more changes than I would like, even given I had much of what I needed.
I have no issue with resto mods and prefer them to be reversible but if the bike is a major rebuild needed, then I don't have issue with it.
i had some guilty feelings knowing it would be going to some group that didn't hesistate to put the grinder or cutoff tool/saw to the frame, tanks, etc. But, I needed the money worse than my feelings would have prevented.
