Removing Clutch Plates

You can get a piece of thin wire, e.g. locking wire, past the plates and hook 'em. Or try putting it on the sidestand and spinning the centre - they often fall out.

Plates get gummed up with oil. Thin wire with end made into a small hook you can get round the edge of each plate does the trick. If clutch slip still present after cleaning off plates and adjusted correctly probably need a new set of friction plates - have experienced this a few times over 50 years with three Commandos.

A couple of corkscrews work very well. Espescially the one on a swiss army knife.... Odd but true!

It may not work, but perhaps try blasting a "brake cleaner" degreaser behind the plates. I usually put the bike on the sidestand and give the clutch drum a few taps with a hide mallet. They only have to let go of the drum backing plate.They don't have to come out one by one.
