Help needed for new “used” Mini bike

Hello all, I purchased a mini bike off market place. The guy didn’t know much about it as he got it in trade for a job he was doing. From research I’ve decided it’s a Baja warrior 200. It has a new predator 212 swapped in it and when I opened the clutch cover I found a torque converter. The problem is the whole inside of the cover is a fine coating of rubber dust. Looks like it’s eating the belt. I’m not sure of the brand but I did Google the belt info and saw it was sold by go power spots for a 30 series torque converter. Any help would be greatly appreciated in getting this thing back in tip top shape.
