I was at a local bike shop was asking the service manager (whom I ride with on a few trip) about the M109R. Ask he if there was any new service notices. He said "No" Ask him about engine distortion on large compression engine such as the 109. Asked if low octane low could do engine damage. He stated the engine would run rough but no damage. But he had seen major engine damage when people use FUEL INJECTION CLEANER. I would damage the piston and ring quickly. He said it would lower a 91 octane down to 60.

JUST A FYI
