Well, it is time for the update of work, done to the 420sel. EHA was in need of being set and was done,then the duty cycle was set at Idle and 2500,this is at 60.2% the EHA is at -0.0 to + 0 to 0.01 threw 2500 to idle. The eng.runs well but for a start up roughness, then smooths out. the last peace of the puzzle is the potentiometer,it has failed all test given and one is on the way. all in all it has been ten months but well worth the time spent on a classic ride and those enjoyable trips. Other sights in my name will show a more details of the journey.jnt.
