Hi Tiger_cub, Good! Not flat surfaces is root cause of many (most??) leaks on Triumphs. Flat surface & modern sealant guarantees no leaks. To see exactly what I mean look at by motor overhaul thread on Triumph RAT. Surfaces were a mess. Lots of photos. Don
The leak from the lower stud is still there, just not as bad. I will try to seal the threads of the stud with sealant. Interestingly, although the bike is currently leaning over to the left on the side stand, its leaking from the right side!
