Having problems with the rubber diaphragm that fits over the clutch release piston. OK I admit, I lost the original, or the dogs have eat it the main agent gave me (PN:23163-06B00) but this looks like the seal that sits behind the piston. This is typical of the service in the UK, I told him it was the wrong part, but he knows best. I have removed the complete sprocket cover and will re-bleed when it is sorted. Please guys have you got the PN for the rubber diaphragm so I can order it, without it fluid phisses out
