First rev after :20 in the video. I give it gas, hear a popping sound and no power to engine. Not sure if related, but while starting the bike in neutral for the past 2 days, I've had an issue where it will jump from neutral to 2nd gear as soon as I start the bike; jump forward and stall out. I did put 93 octane gas in the bike the day before this backfire happened from a fairly sketch gas station. The bike has around 170 miles currently. Oil levels / Coolant levels are all good. As far as the acceleration, it feels like I need to give it more throttle than I did when I first got the bike to get it moving. Also seems to be idling somewhat rough compared to when I first got the bike. Just trying to guage whether I should bring it to the mechanic, or if this is somewhat normal before I go spend money on it. I'm just frustrated having issues like this on a brand new bike.
