I have a Shark Vision R helmet and due to a warranty design issue I've been supplied with new baseplates and visor. The problem Im having is how do you remove the old baseplates? There is a plastic cover over the RH baseplate and under that what appears to be a screw. I'm concerned  cant get the plastic cover off without breaking it. Can any one tell me how to do this?

Chris. Not trying to be cute but google that one. I just looked at plenty of YouTube videos on a variety of their vision helmets. 

Nice PHD. I mean who cuts up a perfectly good bowling ball though?
