How can I handle a clutch plate cover oil leak?
If you do not want to drain the oil, lay the bike (CARFULLY!) down on its left side.. let the oil settle down, Remove the right case, carefully clean ALL the gasket material off the engine case and the cover! make sure there are no dents, dings, scratches, etc on either surface!! Get some quality gasket sealer - NOT ANY FORM OF SILICONE SEALANT!!! I prefer yamabond #4. CARFULLY PUT A small BEAD around the face of the outer case cover face and place the NEW GENUINE OEM GASKET onto the case and make sure its seated fully around the case, you can use the screws to hold it in place until it dries. WAIT until overnight and it fully dried and seated/sealed. Now, carefully put a small amount of good heavy grease on the gasket then carefully install the case ..tightening in a criss-cross pattern until completely seated, then fully tighten all fasteners. If you do it right,, it will NOT leak!
