I have a 04 Ltz and it was blowing out white smoke so we quit riding it. I didnt have time to mess with it so it sat for like a week and I tried to fire it up and it would crank but it wouldnt fire up. I checked the oil and it was very milky. Did I mess up by trying to fire it up? If i remove the plug and blow out whatever water could be in the head and then change the oil until the water is gone is possible that no damage is done and it could fire up? Or is it time for a top end rebuild or somthing else... suggestions please.
