I agree with the comments on the Interstate tank and seat changing the riding position. I'm "inseam challenged", and my Interstate seat has a height that you really notice when you switch to a roadster. I've recently acquired an original paint candy red tank and MKIII roadster sidecovers, and I'm going back to roadster which my MKIII was when I got it. Not going to part with the Interstate equipment, since I'm prone to change my mind.
