Our reply: "The instructions that come with your YZ450F 1.5" YamaLink are super simple and give a few options for setting up. At your weight I'd start off with resetting the race sag at 96mm, turn in the rear shock's high speed compression at least 1 full turn and then turn in the rear shock's rebound 2 clicks. For the forks I'd slide them up in the triple clamps about 2mm.
Use that as a base line. Then see if your rear sag needs more or less (example: it could need one more turn for less sag at 94mm). And changes to the front fork in only 1 millimeter increments makes a noticeable change; there is no 1:1 ratio with the rear because changes to rake/trail (the front) effects your 450 geometry at a much different rate.
