I read somewhere (on this Forum) that cork inserts (for a mid fifties model) are a No-No.
Regrettably I had already bought a load from RGM for the clutch chainwheel and fitted them.
I now have clutch drag. I've checked all the usual culprits; p/chain tension, even lift of clutch, correct adjustment of cable, clean plates,etc. It worked before so it's nothing fundamental.
One additional point, I've had to leave an insert and a plain plate out of the cluster as I can't get them on to the clutch hub but I can't see that this would cause drag.
So it could well be down to the cork insets. If this so so, why does RGM still sell them? Rhetorical I know, but it does seem strange for a Norton supplier to supply parts that are inappropriate - if indeed they are?

I believe that the Ferodo was fitted to all post-war bikes and seem to remember reading about how it was "oil resistant" or some such.
Cork is a really nice material - I had a cork lined clutch on my Sunbeam and it was very smooth - but does tend to compress so more likely to drag. And if it's allowed to slip to any great extent the corks burn.....

Thanks for the response, Ian. At least I've got them only on the chainwheel.

Just an update - clutch drag sorted by loosening off the p/chain a tad and relocating the clutch operating arm on the clutch arm to give absolute maximum movement.
Nevertheless my query still stands. Are cork inserts taboo over Ferodo pads?
