Hi all. I’ve not long purchased a 2011 Beta evo 250 to start my trials career. But ive now noticed the oil in gearbox is milky.I’ve changed it a couple of times but keeps coming back so I’m thinking possible water pump seal.So ive purchased one.I know how to get to the seal but wondered what’s the easiest way to pull the old seal out.Am I able to drill a small pilot hole in it to put something in to pull it out or is there a easier way.Thanks in advance.
