I have a like new condition blue and yellow CA plate for my 70 K0, which was removed from my bike back in 96 (replaced with a new plate, clueless previous owner....). When I registered the bike earlier this year, the DMV wouldn't let me put the old plate back on. Wouldn't even give me a good explation why either. Our government servants at work....... Anybody have any experience with this kind of thing in CA? I'd love to get this excellent condition old plate back on the bike.
