I put a SHR860 in my slead with RKT head. So I have no need to keep the stock head around. The head has about 1700 miles on it. I had the head cut to run at 6k on pump gas. I do most of my riding in the snowies and it gave it just a little more snap. Nothing wrong with this head at all. email me for any qurestions, cdbrenden@oppd.com. $210 shipped to the lower 48.
