Thanks for the info.
Are the ferrules left hand or right hand thread? By tapping them anti-clockwise, I might be simply tightening them (because they are not shifting).
Any one got a good set of 600 long stroke barrells and pistons (with rings and including water dome)? I’ve got a slight bit of piston slap on the RHS, so might as well go the whole hog and replace them.
