I just swapped my forks from Marzochi to Showa adjustable. I already had a Showa adjustable rear shock. I did not rebuild the forks before installation and must assume they are stock. I weigh about 200# ready to ride. I adjusted both ends as per the Haynes manual as a starting point. The forks seem harsh compared to the Marzochi units. If you are running a similar set up and weight, let me know your settings. Thanks
