I'm just getting started in the bike world to get away from street rods a while. I need a website or something that's like a bike spotters guide for newb dummies. My old hometown is full of old bikes. I know where a couple late 70s to early 80s KZs are. What all different models of Kawasakis and KZs were there from late 70s to early 80s? Was there rarer models? Some more sought after than others? I've mainly had Kawasakis but like them all. I'd probably buy just about anything priced at a few hundred or less. I'm already going Tuesday to get an 84 GPZ550 for $250 that's been sitting since 1988 in a shop. I love GPZs but also want something older for a café build. Also, what models do I stay away from that parts are obsolete?
