Slightly off topic my second compensator started rattling like a bag of nails just like the first one did, so this one having a grease nipple in it I thought I would give it a splash of grease.

Not too sure how much to put in I tried about 8 pumps with the grease gun then went for a test drive, no change.

Back home with nothing to loose I put about half a cartridge in, what a difference no noise at all.

I used JCB High Performance blue grease.

Note to self, keep your nipples well greased!
