So my Supersport has 37,000 mi and I have noticed a little slippage somewhere between 4k-8k rpm. After some DMF study it looks like the best solution would be to replace plates and springs. The 750 does have a wet clutch and I'm thinking Barnett plates (model 306-25-10001) and springs (model 501-44-06002.) Looks like a straight forward job, just thought I would ask for opinion so I don't go down the wrong road. Thanks!
The Barnett setup for a wet clutch works well from what I hear.
So I installed the new clutch plates and springs and now I can't get the clutch fully disengaged. Makes it impossible to put in neutral when engine running and at a stand still [bang]. I bled the clutch slave and it had no effect. Any ideas?? Thanks!

Try removing two of the springs.
Some people have problems with the Barnett springs being too stiff causing drag.

That exactly matches the performance I got from installing a Barnett pack in a customer's S2R800.
That's an APTC clutch, but still the same issue.
Ended up replacing with OEM plates.
