I really appreciate everyones input.
What makes this valve situation interesting is that the other valves have plenty of adjustment left.
As jkv45 suggested, I suspect the seat is becoming recessed into the head. My thought of shaving the end of the valve would be to remove the rocker arm, cover everything and carefully remove material above the keepers with the valve in place. I have no idea if this is actually possible without causing more problems. End the end, an engine swap may be the best way to go rather than just rebuilding the cylinder head.

Edit: Looking at some images of the cam rocker assembly it would be difficult but not impossible to do this. I am not in a hurry to remove cams though.

To top it off, my wife has suggested getting a newer bike and I am sure we all know how dangerous that is!!
