Hi everyone. My friends wife is selling departed husbands Trike. HD2010 6spd fitted with a manual change Champion reverse gear setup. Help needed the after a so called mechanic went for a ride.Came back put it or tried with out reading instructions in to reverse. I was not there at the time. I got a call and told the trike will not move when engine running. Not fwd/revs. Any info would be good.
