Thats a lovely looking Kettle (nice and chunky). It was my dream bike in the 70's - until my mate bought a brand new red one. After a couple of early goes followed by a week using it I was glad to give it back. It was heavy slow and thirsty. He kept sliding off it, nothing serious, but it ended up in his garage totally stripped and left for years. half of it went to the tip, the engine was sold in MCN for next-to-nothing, and he gave up bikes.
Gotta say though I still love the look of them and would probably buy that one no probs at all...hehehe
