Fit as it needed to and added a little inertia to the motor over the aluminum plates

The clutch kit is exactly what they claim. Very good quality and fitment. I would purchase another kit when the time comes.

great kit with only minor complaints. 3 shims of each size when a bike uses 4 or 5. Rare that all 4 or 5 valves may need the same size shim, but its possible. 2nd complaint is the number thats etched onto the shim face doesn't last long regardless of being against the bucket/lifter or against the valve stem. 3rd is that they dont offer 5 packs of these to replace an empty spot in the case... they are available individually, but for the price each just refilling one spot it starts to get pricey fast to the point of just buying another kit.
