Replacing master cyclinder?
I would do it just to be on the safe side. And while you have the master out, do some good heat insulating on it. My recipe is overkill but consists of alum foil, a heat sleeve, heater hose, then accel fiberglass spark plug boots over it all.
Sounds like a lot but those spark plug boots are fantastic. 2000 miles with one laying against the header and it didnt even turn brown, and the plug boot looks brand new.
