Hi, I always run premium unleaded fuel in the bike and was surprised today to hear the engine pinging when I opened the throttle. The bike always gets filled with Mobil premium unleaded (not the super expensive stuff, the next one down). That stuff is rated at 96 octane, which is 5 points better than what the manual recommends. It was kinda warm today - would that make the engine start pinging ??? It happened while climbing the gladesville bridge in 4th at 70k`s or so...
