charles why would you choose shock technology the same age as tye bike you are building?
there is so much better stuff to swap in even a kawasaki ex650 has a similar install
its not known as a great shock but its at least from 2000 up
if you want the same set up style in a cruising version the kawasaki versys 650 or 1000 shock would be my choice
and you can get all sorts of springs ect
