I did the 1.5 shim mod a short while ago. Used a strap on the moveable sheave to tighten it. Worked great. Shims are super easy to install. Just pull off the movable sheave and the collar. Put on your shims on the shaft and then the collar. Lastly put on the movable sheave. Just make sure you keep the cam plate tight to the movable so the weights don't flop over inside. Then just torque the nut.
