Thanks for the different perspectives on this clutch shim mod. I am not a picky rider but when the adjustments are easy enough to try out...I just go ahead and test them for the fun of it...and to learn. I have done the original clutch mod (which did make a noticeable difference), added the shims (nothing too noticeable) and did have washers under the clutch springs. I took the washers out when I put in the shim, but I think I am going to put those back in since it did make a difference on the clutch pull. I need to ride the bike on real terrain to see if the shims make any difference or not.
