Okay I need any type of help ASAP! On my kikker 5150 chopper, the rear sprocket obviously has some problems.. when I push the bike, it doesn't spin when I'm in gear.. it won't go into any gears.. and when I jump started the bike it wouldn't go into gear but the chain would spin as I revved up the engine! Please help me ASAP! Just any type of idea.. also, I'd like to try to fix this without spending any money cuz this is my daily driver n I don't get paid for another 2 weeks.. THANK UUU!
