I was driving my kawasaki 125cc eliminator down the highway when I heard a loud pop. It sounded the same as when you change gears, except I didn't touch the shifter and the bike started slowing down. Once I let off the gas it died and I had to pull over. Immediately after the incident I noticed I couldn't switch gears and I was stuck in first, and it wouldn't start. That was last night, and now I can get it to change gears but it still won't start. You know how when you start a bike, even if it doesn't turn over it still fluctuates in sound? well when I try to start it, it just makes a loud whirring noise like it's spinning but nothing is connected to it. I don't know much about bikes so if anyone has any idea what it could be I'd be in your debt
