Question about 1984 Honda CB 700 SC Nighthawk
Your motorcycle has hydraulic lifters that run off of oil pressure. Your valves never need adjusting. Now the problem, the hydraulic piston assembly that operates the individual valve can go bad . This will cause a loud clacking or clicking sound. If you have several bad lifters it sounds like your engine is full of marbles. Early models in 1983 had quite a few lifters that needed to be replaced. The Honda dealer knows how to test individual lifters to see if they are worn and need to be replaced. One other possibility, you could have a bad cam chain tensioner . That can cause an even clatter/clicking sound and can usually be installed through the top of the motor
