Yeah, operator error. The bike holds 3.9 quarts and most guys just put the whole 4 quarts in. Are you sure that all of the old oil drained out. There are two drain plugs on the X. Did you change your filter. You also have to give it time to drain back down after starting.
You are checking the bike sitting level and not running correct.
also you could have bought a 5 quart jug on accident and didn't pay a lot of attention to it. I did that once in my car. lol
FYI, I usually only remove one drain bolt as the other one never seems to hold any extra oil in.
