Initial setup: 6.2 grams per arm 2 9s 2 13s 2 18s 02-01-2023: 9, 11, 21 5.7 grams .75 = 90 lbs static To go with the #9, #13, and #18 combo, .100" shim would be recommended to start. This is for a launch RPM between 5500 and 5750. Also, with the other specs you gave me, you should only need about 6gr per arm. use 10 grams for 1000 HP. static springs: The static springs are at 1.315" installed height with a .110" air gap. At 1.315" installed height, each spring is 9 lbs. .010" shim. Each shim adds about 1 lb to each spring .025" shim. Each shim adds about 2 lbs to each spring .050" shim. Each shim adds about 4 lbs to each spring Tuning: Weight Change on Arms • Putting weight on the arms makes the clutch more aggressive. • The rate of lock-up per RPM increases. • Solves slippage at High RPM’s. Dynamic Spring Change • Installing higher spring numbers delays the timing of the arm engagement. • This adjustment is used to tune the launch point. Static Spring Pressure Change • Adjusting the number of shims under the static spring, just shifts the curve up or down. • Static spring pressure is mainly for driving the bike to the line. • Baseline pressure. Troubleshooting: • rpm going up, bike not going, move to lower springs • if RPMs go up then come back down need more pressure.. static & dymanic • when it come off 2 step needs to be at friction point • burnout at high RPM • add weight to arms if slipping
