Move the vehicle forwards, or turn the

wheel, in order to be able to check the
vertical oscillation of the chain even
when the wheel turns; the slack must be
constant in all the rotation phases of the
wheel.
WARNING
If in some positions the slack is higher
than in others, this means that there are
crushed or seized links; in this case,
contact an aprilia Official Dealer.
To prevent the risk of seizures, lubricate
th e chain frequen tly, see p a g . 6 7
(LUBRICATION AND CLEANING).
If the slack is uniform, but higher or lower
than 30 ÷ 35 mm, adjust it, see pag. 67
(ADJUSTMENT).
