MilkToast, read your manual,,,,,,it says to use 87 octane (regular) gas. Just because someone else owned the bike, doesn't mean they actually know anything about what makes it work. Burning premium in your M50 is doing two things, one, it's costing you more money, and two, the motor is running hotter, because higher octane gas burns hotter.
Higher octane gas does not give a motor more power, and unless your motor is designed to use premium, you are actually doing more harm, than good by burning it.
