If your bike is too aggressive, then you need to reduce the amount of static spring pressure. If you have shimmed the springs, then you need to remove some of them to reduce the pressure. If your springs are not shimmed then you need to get some softer springs. The launch of a lockup equipped bike is totally controlled by the clutch springs. Your lockup does not start to apply until the bike is in motion, usually about 10-20ft off the line depending on the type of lockup you have. MTC stocks softer clutch springs for a number of applications, so give us a call.
