SnwPro, right on. That is a fact, (127) too soft. (067) better belt. 2000 MXZ 700, here is what worked for me. Goodwin 215-375 red spring, Goodwin, Blue secondary, 17.4 grams of pin weight, 54-48 Helix, 287 ramps. This setup rocked 2-3 sled lengths over stock. If you weigh 170-190lbs. You will be ok with this setup.
