Has anyone added 1 or 2 pre-load washers to their forks? I see in the manual that they are assembled without any, but you can add up to 2 to stiffen the forks up a little. I'm just curious if they have any effect on the fork...positive or negative. I know that they really need to go to a tuner for a re-valve, but $$$ isn't in the cards for that right now. I was just thinking that if I can add a little pre-load to them then it may be a cheap improvement. Other than the forks....I think my 07 is one of the best off road machines out there!
