Received my MM tips and I've got one changed successfully, I'm having a nightmare getting the other one off though. The screw unscrews a couple of mm then keeps rotating round. I've sprayed some WD40 around the screw / between the exhaust and the covers and left overnight but it hasn't made much difference.
Tried pliers, wedging something in between the tip / screw but no luck!
What next?
