This one wasn't mine, I had a red one. As I recall, it was only imported to the US one year, it was about 1986. I bought mine new from a dealer who had it sitting on his showroom for 3 years before I bought it. It was a 4 valve head, overhead cam single cylinder 600cc. It was a kick start only. She was an easy starter hot or cold, but anything in between, like warm, it required multiple kicks. Big 4 stroke singles like to hiccup and die at stoplights, and there is nothing like trying to kick start your bike while traffic behind you waits impatiently at the green light while you block traffic. I really loved this bike though. It was light, and with a pipe there is nothing that sounds like a bike 4 stroke single.
