Yes, yes and yes to all those my friend.
And whilst it's in the "somebody's thrown a hand grenade under it" state, best also refill the clutch hydraulics with brand new DOT4 and whilst you're at it, check your clutch slave cylinder hidden on the back of the gearbox behind the transverse bar; another e.g. of BMW's parsimony. Designed for an upmarket pushbike, the tiny bearing contained in the under-specc'ed unit goes west for fun, particularly if you ever stand at a light or a turn-across waiting with your bike in 1st and the clutch held in. That miniature bearing is spinning on the end of the clutch actuation rod constantly at engine revs., something it was never designed to do for any extended period. Dry clutches must be either in or out at any one time - nothing inbetween. i.e. always just grab the lever, snick into a gear and immediately feed out smartly as you match the revs.
NEVER SLIP IT ! You canwith a wet Jap clutch, never with a dry....
Even your new replacement slave, best bought from Beemer Boneyard, not BMW, will need careful application by a toothpick of some nice blobs of bearing grease ferkled fiddlingly into the balls.
Happy wrenching !
