I had my 2004 Yamaha R6 sitting out in the lot and there were heavy winds and rain over the night but the bike was covered. I think the wind somehow caught the cover and acted as a parachute and pulled the bike over because it was laying down on the opposite side of the stand. The bike was probably on its side for around 8+ hours. I turned it upright let it sit for a day and cranked it and it would start up but it sounded awful and the engine wouldn't stay running. I think rain got all up inside it but I have no idea what the problem could be. I tried pulling the spark plugs but after that the engine wouldn't even start up it would only crank. Any ideas?
