Has anyone else had trouble starting their street 750. I just got a new 2016 street 750. When i first got it it started without the need to rev the engine, i would still wait a few minutes for it to warm up before takeing it out. After my first tank of gas i filled up at walmart using super unleaded 91 just as they told me at the dealership and since then when i go to start my bike if i don't rev it for a minute or so then the engine sputters and turns off. I don't know if this is normal or maybe the gas was bad. I have only filled up the one time and plan on going somewhere else like phillips 66 or shell at the next fill up but still i am concerned. Is this normal?
