I got my rear shock rebuilt and resprung. My goal was to do away with "weave" when hauling HB bags at approx 80mph around semis. When I tried to adjust the shock, the clicker wasn't working. So I got it rebuilt, with a stiffer spring, clicker working. I discovered that that the bigger issue for me was the front set too stiff and had little compliance and would "bounce". So after the softening the front, this made the changes I was looking for.
If I wanted the forks to be revalved and the spring changed out, I'd call Race Tech and get a Gold Valve Kit. Personally, I think the front is stiff enough.
I suppose I am one of the few here that have some of the worst issues but still am satisfied with the OEM parts after a repair and learning to adjust it.
