so i read on here a while back that several of you have been running 87 octane in your bikes while fueling up today i put 87 octane in my bike and my buddy on the r1 completely dissagreed saying that it is a high compression engine and requires high octane which i dont dissagree with but the difference between 87 and 93 really isnt a large difference in my opinion what are your thoughts on this
