Was well ratted out by the time I got it (in early/mid 70's). Couldn't pour oil fast enough into it to keep it topped off. And just thinking about the Lucas electricals still gives me nightmares. But it was fun. Love British parallel twins.
First bike was a 1968 Yamaha 80, God bless my parents who bought this bike new for me when I was in 8th grade and within weeks I had it reduced to a beater trail bike.
