I posted this in the suspension forum, but wanted to see what the Yamaha guys were doing. 2008 YZ450 I weight 190-195 lbs w/o gear. Riding type is Off-road/desert, Novice Front travel from manual: 300 Front extended: 613 Front static: 581 Front rider: 527 Measured from top caliper bolt to lower triple clamp bolt. Rear travel from manual: 310 Rear extended: 625.5 Rear static: 590.5 Rear rider: 514.5 To me the rear feels fine and the numbers are really close. I never really like the front. It seems like it's always too stiff in rocks or too uncontrolled in whoops. I can adjust clickers and be satisfied with one or the other, but not both. Since it needs fork seals (again) I want to at least get the front sprung correctly. RaceTech calculator recommends .487 to .505 depending on my 5lb weight fluctuation or adding a larger tank. I don't think my IMS3.1 is really adding that much, but I know it's there. Stock springs are supposed to be .47. So, do I go for a 2% increase to .48 or a 6% increase to .50?
