I ride my 72' to work everyday. It is all original except a front tire and carb. The original carb ran but would die at stop lights for no reason. Very tempermental. The shocks bottom out easy with 260 lbs on them but a slight lift of your legs when a bump comes and it never bottoms out. Engine does smoke out the exhaust and crank filter. Leaks a little oil out of side cover. It's wore a bit but keeps right on turning. Biggest problem is traffic coming up behind you fast then swerving. When the carb is on, it does about 28-33 on flat ground. Not bad for a 4 hp.
