We snapped the cable for the "enrichening" cold start lever on our 2011 TXC 250. I have no idea how, my son came in during a race when we discovered it. After looking at this closely, is there a better way to set this up? Is there an easy way to replace it? it looks like the cable is permanently attached to the red lever. Could it be set up with a knob right on the throttle body? Thanks
