I have a collection of anti-wet sumping valves in a box; have been removing them from my bikes.
No blow-ups because of them, but noticed that when air enters the oil galleries (ie; after having drained the oil from the tank and then re-filled during an oil change), sometimes the pump fails to prime.
Have decided that (Valentino Rossi like) I will get on my knees and bow to the bike before riding it (and also drain oil from sump plate at same time!).
To confirm the pump has primed after changing oil (especially if you continue to use the anti-sump valve), remove plugs, remove oil relief valve, and turn engine over until oil runs out of the relief valve port.
