I put the YZ needle in my 05 a while back and I checked the oil a couple of days ago and it was a little over full and smelled like gas. I know something isn't seated right somewhere but I've never had this happen to me. I don't turn the gas off when I shut it off and it couldn't have been very much gas to get into the oil or it would be coming out the hole when I pull the bip-stick out. I'm guessing this was a one-time deal because all the one's I've seen where the carb was letting gas in flooded the bottom end. Its running perfect. Anyone had this happen?
