The valve travel times (up->down, down->up) are measured
and displayed. If these measure < 1 second, an error
is displayed and the valve travel time must be set
to at least > 1 second using the throttle screw(s). This step may need to be repeated
several times until an optimal valve travel time
can be achieved. Experience has shown that valve travel times
of approx. 1-2 seconds produce optimal control characteristics. The
two valve travel times should ideally not be
too far apart.For further information, see chapter
