Hello all, new to the forum here, also new to go karts. I bought this for my son and I’m not the most mechanically inclined but I can do enough. He was riding the other day and the chain came off and wedged itself inbetween the sproket and tire. So I decided the easiest thing to do to get it off was to take the tire off to get to the chain. While I did this I noticed the hub assembly had a bearing inside and all the balls inside the bearing were falling out. I’d assume I have to get a new hub? I don’t see any way of getting inside to replace the bearing itself. If I do have to replace the hub, does anyone know where I can get one? Thank you all for the help!
