In relation to this thread, yesterday was my first fill up for the tank and the first question that came to me at the gas station is what grade of gas should I use? Tried to look for the info anywhere near the tank but I was out of luck so I just went with the middle option and chose the 89. but last night I was trying to figure out how to hang a helmet to the bike so I take of the back seat and find a sticker at the bottom of it saying that I have to use a grade 91!!!
I will snap a picture and show to u guys!!
