Just got a '72 CB 175 - my first bike! Runs and is in mostly good working order, not bad cosmetically either. Some maintenance and minor repair work required which I'm marginally confident I can do. Tires are in pretty iffy shape so my question is this - I'd like to take the wheels in to the shop to get the tires replaced. Any advice on a proper center jack or lift for a bike this size? Any advice period? Thanks all.
