I’m very new to mini biking and this is my first ever project. I have a predator 212, with a stage 2 kit from gopowersports, torque converter, and mikuni vm22. I just got it running a day ago and today i took it out to break it a little bit. It was running great and I was riding the whole time low to mid RPM. Then all of a sudden the back wheel locks up on me and the engine stalls. Now the back wheel will not move at all. It only moves whenever the pull start cord is pulled. I spent so much time and money on this project, really hope it isn’t blown. Here’s a Youtube video showing what’s going on.
