So I was doing the 8 rib converstio today and here is my problem. I hope you guys can help. I got the 2 pulleys ( Smooth ones ) on and they spin fine, but the new pulley from ZZP anytime you screw it in the dam thing locks. It becomes so tight it wont move. If anyone has dont the 8 rib conversion did you guys get things besides the pulleys. I even tried to change out the bolts and see if that helps. At this point im at a loss I dont know why this is happening??
