Here's the pic of the piston with it's broken o-ring which was around the psiton as a piston band. It's out of a RM80 99-00 (imho96-01 should be the same though) anybody has an idea what piston this is? imho it's not the standard one. Now i'm looking for either the correct piston band or a new/used piston. OD is 32mm, ID is 10mm, rod OD is 12.5mm Any ideas, gentlemen? .
