I'm new tho this type of ride and have never taken a good look at the bars, but could you not just fashion a spacer to raise them up 1-2". Since the whole triple is on an angle, raising them would automatically bring them back towards you as well although not much.
Looking at the manual now, it doesn't say much and the diagram shows the studs but doesn't say if they are removable. Is this a 1 peice unit? Most likely eh? I say if it bothers you that much, just buy a new set for $200. Cheaper than a new $700 seat
