I recently had a full engine rebuild on my 150sx. When i put the magura clutch back on, the slave cyclinder piston didn't sit flush with the surface so i pushed ithe piston in a bit. When I tried putting the bike into gear and pushing it with the clutch held in, I got no movement. So I got eurotek to send me clutch fluid, they send me 5.1 clutch and brake fluid which I found very strange but thought they know best and put it. I have found out since this is a terrible idea and am going to drain and bleed the clutch with the proper mineral oil. Will the clutch be damaged at all? anyone know the proper procedure for refitting one of these things?
