Rear Drive Chain Slack Adjustment
CAUTION: Never adjust or operate the vehicle with the rear drive chain too
loose or too tight as severe damage to the transmission and drive components can
result. Chain tension must be inspected with the swing arm in the position shown
in illustration.
Check the amount of chain slack by moving the vehicle slightly forward to gain
slack at the top side of the rear chain. Collapse the suspension by using an adjust-
able (buckle type) trailer tie down. Fasten the strap around the axle and rear bum-
per tube. Tighten until a straight line (A) can be drawn from the axle to the transmis-
sion output shaft intersecting the swing arm pivot. This establishes the tightest
chain position. At this point the chain should have 1/4"-1/2"(.6cm-1.3cm) deflec-
tion. If the chain needs adjustment, use the following procedure.
