The fork is more than night and day different, and a huge improvement. The '04 shock is pretty good, though. The '06 has a beefier shaft, and several other little updates, but there's not so much that I'd look for one instead of having the '04 re-worked.
I took a look and I believe that the rear shock is also set up for a 50lb less than myself guy. Instead of spending $100+ and a new spring and then going to get it all revalved I was thinking about swaping to a newer shock as well. Seems like it would be more cost effective and slightly better than the 04 like you said. What years swap over, and is it a direct swap or?
Standard original settings for the '06 were 11 clicks out from all the way in on compression and 7 out on the rebound. From there, follow this general guide:
Thanks again, I printed that out and will try messing with it at the track this weekend at my bachelor party to see how it works. I'll be taking the forks in for a revalve
though in a few weeks.
