i dont know if this helps but i put a socket in the top of my mc16 forks to stiffen them up to suport my weight.

basicaly found two sockets the same size in my tool box that just fit inside the stantions and placed them in between the springs and the tops.

dont know if this helps you, it did effect overall travel but then again when i sat on it before it just pushed the forks down so i had less travel anyway.
