Just got this bike. Owned only two strokes in the past. I just bought the honda hi performance four stroke oil and the Honda HP transmission oil. Got home and the HP trans oil said for two strokes. Can I put this in my 450r transmission? I hear you could, but want to double check before I do. I hear most people put the same oil in the trans as they do the crankcase which I will do from now on but want to use up the trans oil I bought.
