17.1 During Break-In Period
A factory-new machine should not be run at high
revs (full throttle off load) for the first three tank
fillings. This avoids unnecessary high loads dur‐
ing the break-in period. As all moving parts have
to bed in during the break-in period, the frictional
resistances in the engine are greater during this
period. The engine develops its maximum power
after about 5 to 15 tank fillings.
