Well if I leave the bike 3 days I will have nothing in the oil tank its all in the sump, I dont know why its so drastic but until I have the engine apart again (which if I have my way wont be for years) then its staying with a wet sumping vale :)

And I though mine was bad, 2 weeks and get about 500ML out the engine! the A10 that is, the A7 can leave that for months and still OK.
