Hey all, I’m new to pit bikes so I bought a used one that wasn’t running. I have no idea of the brand it only reads DB-21B in the handle bars. Today I got it running and rode just fine. I shut it off and when I tried to start it the kickstart was hard to do and the bike lunged forwards and would not start. The bike will roll backwards but not forwards. Any help would be appreciated, please remember that sometimes I have no idea what I’m doing.
