81 cx500 custom
New to me 81 custom, PO said was coming from trans cover gasket and he smeared silicon? Over it. After aquiring it yesterday, it lost approx half quart oil during twenty minute ride. Just pored out under the fan along the cover. Tore it down and found this. Just wondering if anyone else has had this same looking leak before I go tearing into things. Maybe tach seal? Also no oil in coolant nor coolant in oil.
