If you are planning on bringing your stock clutch Hayabusa to the drag strip, or somewhere else you’ll be launching hard from a stop, this modification is a MUST! With your stock clutch, you WILL experience Banging, Chatter, and Bucking at launch. Those issues left me wondering “What am I doing wrong!?” Well for once it wasn’t me, but a mechanism in the clutch referred to as a Back Torque Limiter and more commonly known as a Slipper Clutch. This device prevents sliding the rear tire or over-revving the engine during aggressive downshifting. But at the drag strip it causes inconsistency and frustration. Though there is more than one solution for this mod I went with Brock’s Performance Clutch Mod. (Not sponsored! Just my recommendation). I’ll show you how it's done!
