WARNING
_
• Be sure that both tie-rods are turned the
same amount. If not, the machine will drift
right or left even though the handlebar is
positioned straight. This may lead to mis-
handling and an accident.
• After setting the toe-in to specification,
run the machine slowly for some distance
with both hands lightly holding the han-
dlebar and check that the handlebar
responds correctly. If not, turn either the
right or left tie-rod within the toe-in speci-
fication.
