Steve,
If it helps, I was talking to the mechanic / designer / conversion expert of Authority Sales (the guys who supply the C14 Police version) last week. We were discussing what changes they made to the bikes from stock, and after he finished his list, I mentioned the clutch.
He said they make no changes to the clutch system on the C14, that it has been bullet proof for them. They have never heard of a single complaint or problem from any of their C14 Police bike customers. He went on to comment on how easy it would be to replace the clutch disks if needed (lay the bike over, pull the cover, don't even drain the oil!).
Considering most of their low speed control is done by feathering the clutch, they are probably the worst for abusing them.
He also mentioned how they upgrade the clutches on every other bike they sell, like the ST's, the BMW's, and all other conversions they've done, but not the Connie.
I figure that's about the best testimonial there is for the C14 clutch.
