De-Grease the bottom of your engine And DRY.
Remove the 2 bolts, are the threads oily? Does oil actually leak out of the holes? Could be porous casting.
With the bike laid on RH side, spray holes with brake or carb clean and use compressed air to dry. 3 times, we want to drive the oil back out of the porosity. Spray & dry the bolts.
Put 3 drops of Lock-Tite blue thread locker into each hole. Put a drop on the threads of each bolt. Put 1 drop Under the head of each bolt.
Install bolts and torque to 80 inch pounds. Allow to cure 30 minutes.
Now take a can of grey or white drying spray foot powder and apply 3 or 4 coats and allow to dry.
Stand the bike up. Check after 10 minutes, still dry? Start it up, check immediately and every 2 minutes.
Modify at "YOUR OWN RISK"!
