Re: K6 v K7 weight
^Other differences that may add weight: ISC, larger radiator, electronic steering damper, hydraulic clutch, 10 button rotors, projector high beam, protective cover on front of gas tank.
The service manual weights are K5/K6: 365 lb, K7/K8:379 lb. As I understand it, these weights are measured in a funny fashion, i.e. all "consumables" are removed. That means no gas, oil, coolant, brake fluid, or (I think) even brake pads. Not sure about fork fluid. But strangely the tires remain. So the weight values are a bit silly. But the weight difference ought to be meaningful.
