is this the only 2stroke that Kawasaki made in 71? I was recently given one thats in pretty rough ( as in missing gauges,seat,small pieces) shape, but no rust, and was considering restoring. Are they worth it? I assume its a 350 mach2..its a 1971 2 stroke, 3 exhaust pipes 2+1, serial numbers in the low 8000´s, but no badges other than kawaksaki. oil is 1.1 liters i think.
