Kawasaki 650r Yoyodyne Clutch install

These are the instructions that came with my slipper clutch.  If your looking into doing the install yourself this would be a good reference to start with first.  If you do not feel that you are up to the task or lack the capabilities to do the install, please take it to your mechanic.  I received 2 sets of spring buckels.  There was a red set and a natural aluminum colored set.  The natural aluminum colored set looks like it might put 1mm more preload on the clutch springs, therefor making the clutch somewhat adjustable.

The tools that I needed and did not have was a 30mm socket and a clutch holding tool.


Riding motorcycles and wrenching since my preteen years, I have moved from motocross to street bikes. Being a teen back in those days it was tough to get me off of the bike. Now days even though I am very busy being a dad I still have my weekends and go to the track to race and on occasion will do a track day or two.
