Rev'd Up

When a client brings in an extremely rare British motorcycle from the 1950s, Rick sets the speed for this matchless mission. Can he steer clear of any old time obstacles, or will this project crash and burn before the finish line? And later, the team has to put their two cents into the restoration of a 1940's Accurate Weight penny scale. Can they correctly calibrate this contraption, or will this hefty undertaking cause them to break the scales?
