CFH87 Posted October 7, 2010 Report Posted October 7, 2010 I've been ridein for quite some time but heard something new today from a buddy of mine if you run any higher of an octane than 87 it can cause detonation. If it isn't true can I run 93 on a bike with a stock head and aftermarket pipes? Quote

If it isn't true can I run 93 on a bike with a stock head and aftermarket pipes? actually, quite the opposite. if you increase the timing and compression too far, then pump gas will detonate. basically, octane rating is your detonation resistance. the higher the rating, the more resistance. adversely, the higher the rating, the harder it is to ignite. so, basically, if you don't have enough compression, higher octane will make less power and start/run worse.
