I'm installing bar risers on the F4/750. I need to change out the stock clutch reservoir to a remote unit like on a 1098. Has anyone taken theirs apart? There is a screw inside to remove but then there is a missing dime shaped plug missing that would attach to the fluid hose. I've seen the plug part for a bembo but do not know if it is the same size. Any ideas? For the front brake I replaced the whole master unit but do not want to do that for the clutch. THANKS BobL.
