I replied in post #3, but thanks to the pic of the 71 H1, I am going to append to that post.
High school bud took me for a ride on one of those 71 H1As before I had my license. Neither of us had helmets, steep/tight/twisty CT mountain road, wheelie out of every turn, not sure I was ever so scared or ever so exhilerated (is that a word?) in my life.
Bought my first Kawasaki triple (a wrecked 74 H2) when I could afford it, at 19. Since then I have owned at least twenty of them.
All but one was bought as a project; only one was a running bike. Usually, I buy a project bike, work on it for a year, get it running, ride it a little, and somebody stops me and wants to buy it--can't tell you how many times that has happened.
I currently have enough parts to put together one, maybe some day two, all thoroughly disassembled, and hope to put one together in the next year.
Every time I go to Mid-Ohio Vintage Days and visit the Kawasaki Triples Club guys, I am inspired anew. Some amazing restorations and resto-mods, great old guys riding beautiful old bikes. If you are interested, check out https://www.tapatalk.com/groups/kawasakitriples/
