I just installed a Goodwin Performance clutch kit on my 2001 zr600EFI.
It is not too hard if you have some knowledge of sleds or mechanical skill. You do need a clutch puller tool and a torque wrench for when you re-install the clutch. My kit came with new wieghts, new primary spring, new driven spring and new helix.So I pulled the clutch off the shaft CAREFULLY . Removed the cover of the clutch,(everything is under spring pressure) replaced the weights and spring.Reinstalled the clutch (should be torqued to 55 ft lbs) Then remove the driven setup unbolt the helix cover and helix . Replace spring, install new helix. Putting the spring in and tightening it down is the tricky part. MAKE SURE YOU MARK ALL PARTS for alignment before you dissasemble them.
Bring on the white stuff!
