When I had my 02 Stone, one of the obsolete boards had a post on using deep sockets, filled with lock washers. You used longer bolts of course, the sockets filled with interlocking washers was placed between the the triple tree and the handle bar clamp. The sockets were placed with the socket part resting around the raised portion of the triple tree. I don't recall if they were 3/8" or 1/2".
I did it, raised the bars and brought them back just enough for me.
I checked them often at first, then maybe once a year.
Worked well.
