Hey, I just got a bike for the first time. When I got it, I could start it fine. A couple days have gone by and it won't start :/ I hear gas sloshing around and I've tried the choke but even doing that it makes a tiny tiny sound when I press the engine start button. I had a friend look at it and he's kind of new but knows more than me. He couldn't start it either. The horn and front lights were really dim and the horn is very quiet. Sound like a dead battery to you guys?
