Worn clutch?

Wow, you guys are quick.

I use standard auto-grade Castrol, but have for the last 7 years.  The 
clutch "I thought" used to engage around the half-way lever position, but I 
may be wrong - I've been riding 3 different bikes.

I was using 10w-30 in past years becuase I did cold weather riding - mostly 
short stop-and-go trips.  But this season I switched to 15W-40.  I change 
the oil and filter frequently.

Has anyone actually needed to replace their GPZ clutch?  And if so, do you 
wait for slipping / odd tach movements, or just a total no-go state?

Exercise your brain! Try Flexicon.
