Clutch plate wear

[Phil C]

I spoke with Draganfly today. They don't know the reason why the new friction plates are thinner than the minimum recommended by unit singles manual- maybe a different friction material? - but say they've sold lots of them and not had a problem.  I then spoke with Chris at Ripe Motorcycles who advised me there had been a BSA service bulletin about it.  I can't find a bulletin about it, so don't know what the minimum thickness should really be, but think I might as well stick with mine for now.   Phil.

I'm sure the main issue is not allowing the friction material to get to a point where you then run the risk before the next major service of them wearing down to the metal and the clutch function failing (ie slipping excessively). You've got just over 1mm of friction material left and that should last many thousands of miles. It doesn't to be worthwhile replacing them with new plates with the same amount of wear left!

I would change the clutch springs - tired old ones do allow more clutch slip!

Thanks everyone. I've decided to keep my old plates. I've also got new springs.
