As long as you fill with the correct ratio of octane booster indicated on the bottle you are fine. Adding too much can affect the fuel injectors or cause the engine to run rich.
Hey Gus! Thanks for the reply. According to the owners manual, yes, premium. I guess the next question to ask what octane level defines premium! Good information and thank you again!Does this bike need premium? I have been running 89 Octsne ethanol free here in Olympia & runs great.
