NOTE:
Before checking and/or adjusting the chain
slack, rotate the rear wheel through several
revolutions. Check the chain slack several
times to find the point where the chain is the
tightest. Check and/or adjust the chain slack
where the rear wheel is in this "tight chain"
position.
To check the chain slack the motorcycle must
stand vertically with its both wheels on the
ground and without a rider. Check the slack
at the position shown in the illustration. The
normal vertical deflection is approximately
15 ~ 20 mm (0.6 ~ 0.8 in) .If the deflection
exceeds 20 mm (0.8 in) adjust the chain slack.
