Hi, I dont usually post on exriders, but i need help soon becuase rriders is down. The right center case of my 87 R needs to get milled on the outside mating surface(where the right crankcase bolts to center case) because it is chewed up from previous owner trying to pry the case apart. The gasket is new but it leaks, and my question is would it be OK to mill .001" off of the case mating surface to get a fresh edge for proper gasket seal. Is this doable without any custom mods? and will it work? i dont feel like buying a new case just for a new gasket surface! thanx
