Hi guys, I am interested to buy a CB750. However I have concerns as owner owns it for 12 years. I'm just scared that the bike will break down once I buy over. I saw the bike, the engine is clean and all the idling is a bit low maybe needs some tuning up. This guy practically lets hai bike seat at the carpark. He recently went for inspection and passed. Should I be concerned about any parts break down? Will it cost too much?
