Category: Clutch: Lock Up
Last Updated: 27 November 2013
If your bike is lazy or is driving through the clutch at launch, then hooking up about 20 feet off the line, you need to increase your static spring pressure. You need to add shims to the tops of the clutch springs. We suggest putting the shims on the top so they can easily accessed if you need to lower the spring pressure. As a general rule, the .025" shims will add 1-2 pounds of pressure per shim per spring. The .050" shims add between 2 and 3 pounds of spring pressure per shim per spring.
