Just bought the bike, took it up my dead end road with a grass shoulder. The bike like killed upshifting into third/fourth, and my rear end locked up and slid out fron underneath me. Knee is scraped, and my forearm is cut up, but the bike will not start. It turns over, but just will not start. I'm hoping it is just a flooded carburetor, but what else could it be? I stopped trying to start it maybe ten minutes after the incident so I could shower and tend to my wounds. Then I came back out a half hour later and tried starting it. Nothing. Kicks over and all that, but sounds almost like its out of fuel. Like it isn't even trying to start. And when I try roll starting it, it kind of sounds sputtery and will not start. I need help.
