I recently got an ELS 4 degree timing advancer. It's awesome, I should have ordered one the day I bought the bike. But I'm wondering if I should run higher octane fuel. Where I live we have 87, 89 and 93. The factory recommends 87 but I always run 89. Should I be using 93 with the timing advanced or will it be fine? I've ran a couple of tanks already and it seems fine, I don't hear any knocking but I do wear earplugs.
