Yep. Drain it down until, with the bike LEVEL (on paddock stand or someone holding) the oil level should be right between the two marks on the oil window. Suck some out with a turkey baster, syringe, tubing, etc. from the fill cap location is the easiest way. Too much oil can actually damage the engine.
