It can only be the gap. After a run my clutch bell would be 65C, which seems to cause the oil in the metal shielded bearings to be fluid enough to run out. After that, then the bearings are running metal-on-metal and don't last much longer.
I tired many different clutch tensions and non made any real difference to the clutch bell temp.
As a last resort, I opened up the clutch gap and hey-presto, clutch bell temp was 48C after a run.
I measured a friends clutch bell temp after a run he did and it was 51C - he's never had problems with the metal shielded bearings.
I hope now that the temp is lower, that I won't have any further problems.
Cheers, Mark.
How much play do you have after the clutch is assembled?
