In Sydney there is currently a bit of a shortage on Hi-Octane petrol, and this has prompted a couple of questions. 1. Can a bike that is supposed to run on 96 plus octane run ok on normal unleaded? 2. If I can't find Hi-Octane and can only fill up with normal undleaded, would adding an octane booster help, or could it damage to my engine (I have a new GSXR 750)? Cheers!
