Grab you front brake as you push the bike forward. How much does it sink? Progressives and a little heavier new oil will reduce that by at least 50%. Since the tubes have to come out to replace the seals it is a quick cheap improvement. I used DelRay #7 fork oil, I think. The springs cost 100$. Ask Kevin how the his TwoTone feels? The forks from a crashed Diavel will fit. Marchesini. 500+ used, if you find a set. In the back, Progressives 440s are expensive 600+, but IMO worth it. The original ones will buck you off the bike in a good bump. I bought 440 standards and set them at minimum preload. 200lbs, solo rider, 07 Classic, novice rider.
