OK, I'm thinkin' since both of the '83's sight glasses in the OEM master reserves are one step above swiss cheese I'd either replace them with another set of OEMs, or.... replace them with a set of 2ndGen masters and levers... which I have already. Has anyone ever comtimplated doing this, or possibly even done it?? Can anyone think of a reason why not?? Any input would be appreciated.... Thanks..
