Just a thought.
All fine and dandy to have a new re-designed clutch, but how exactly do you know that this clutch will not have defects?
Will it be tested extensively prior to sale to prove it is reliable?
Will we be told how it was tested, and how it performed, compared to the original failure prone units?
Let's take a different, perhaps more realistic approach to this problem.
How about a re-manufacturing option.
We obviously know the short comings of the clutches, witness Nikoli's posts, so should be easy to develop a repair process for the units.
This is just a rough template for the process:
1. Examine the unit that is removed from the engine for obvious problems.
2. Remove the ring gear from the clutch assembly
3. Remove the primary gear from the clutch basket.
4. Remove the springs from the basket.
5. Clean and check basket for damage, proceed if all is ok.
6. Procure and install proper spec/quality cush hub springs, then test movement and clearances.
7. Re-rivet basket to primary gear using proper spec rivets, then test movement and clearances.
6. Check ring gear for counter sink holes and sizes/spacing. If ok proceed, if not fix or drill new proper spec holes in ring gear.
7. Bolt and torque ring gear to basket using proper size/spec bolts. Apply loctite for added degree of insurance.
As Nigel stated earlier, the working process of a motorcycle clutch is nothing new. Attention to quality control is something that was in short supply at Norton. Breaking down the stock clutch and building it back up with the proper components/processes/skills would probably yield a reliable unit.
