I was surprised to here about that type of a set-up as well. I have the article someplace and when I find it, a quick scan, and I'll give you a look-see.
I am still doing my pre-season "cleaning". I did remove the rear shock just to see the difference. Even with the front shock preload cranked to the pegs, I still have a ton of droop in the skid. Way too much in my opinion. Wouldn't work without a spring change. I like the idea of the weight savings, but at what cost?
I'll try to find that article.....Dan
