Thought I would post my finding on my 07. I have had the springs for a while just a matter of getting them installed. I drained the fork oil via the small screw at the bottom of the fork not the hex. ATF came out fairly clean good sign. Popped the caps and made a mess oh well. Installed prog spring from Progressive susp and took a educated guess on preload and marked the stock metal tube about a 1/4 inch above the triple bracket. Needless to say thats more than the instructions ask for even max. I read between the lines on everybodys comments about fluid replacement and went with 375 cc of new ATF. The big thing I found when I tugged on the front wheel while it was free floating I had a fair amount of steering shaft play. So I adjusted the nut and I see it has a locking tab that I assume will lock into place when the main triple nut is tightened down which was loose. Am I correct. Over all things feel good. About to run around the corner and see how it feels. I left room for more oil if needed any thoughts on what I would feel if I was under capacity.
