I took my left crankcase cover off to clean out years worth of buildup from the chain that I don't think ever got clean after 17,000 miles from the previous owner. As I was cleaning the inside of the crankcase cover, the green slave cylinder gasket tore. I'm buying a new one from ronayers. I don't see anything wrong with putting it back on for the next week or so until the new one comes back in. What could I possibly damage with a small tear in this gasket?
