Hi good morning i have just purchased a cb750 k3 1973 and i have noticed that it is emitting smoke when revved to about 1500 rpm,
am i in for a major strip or is there another problem.
Just a heads up on this bike it has stood for four years so i have changed the oil and filter changed plugs and added a fuel boost .
Any ideas, please :(

Could be a stuck piston ring/s.
