Something really bad happened with my engine..

#1
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.

Take that black plastic cover off the the chain on the left side. I think your clutch locked up.
Try removing the forward chain or belt before you start the engine.
sounds like a torque converter clutch problem if the wheel turns with the pull starter
Sounds good guys. Really scared blew the engine up. I’m out of town this weekend but will update you guys on Monday

I have seen driver pulley with the belt wrapped behind it. If it’s a CVT it could be as easy as untangling the belt. Although the one I seen this happening to was doing it because the torque converter was mis-aligned. the mis-alignment shredded the belt on top of letting it get kicked behind the pulley.

When you get a chance, take that bolt and washer out of the center and pull the shiny cover off.
There are 2 weights and a couple of springs in there, then another big round piece that presses against the belt. That piece is PROBABLY stuck against the belt. Wiggle it away from the belt and see why it got stuck.

Did you put the belt on backwards?
In your picture, it does look like your belt might be on backward.
There is a flat side and a beveled side. The flat side should be toward the engine.
Oh wow. It does look like the belt is on backwards. I would like to see a picture just after the cover is removed.
The side with the bevels are on the inside of the belt and the smooth side is on the outside. I thought that is the correct way to install it? I’ll have to take a look when I get back Monday to see.

Nope. Wrong. The flat side of the belt goes toward the flat side of the pulley. The beveled side of the pulley is on the outside, and it moves in and out. The beveled side of the belt goes against the moving side. Flip your belt.

Nope that belt is shredded just like when I installed my brand new $30+ 203589A genuine comet belt backwards. Three passes up and down the road and it was half it’s normal size. It also locked it into first gear his torque converter couldn’t have been shifting correctly.

The belt is labeled with arrows (this side towards engine) I’m looking at your picture and it looks like the arrows are facing away from the engine.
Only reason im super confused is all the videos and photos i’ve seen in installing this torque converter have told me the side with teeth go on the inside. Here’s a couple screenshots
