Drive Chain
Adjustments
(
Refer to Safety Precautions on pages 44 & 45
)
Drive chain slack should be checked and adjusted, if necessary, every 250 miles (400 km).
1. Place the Enertia on its kickstand with the ignition switch OFF.
2. Remove the rear axle cotter pin.
3. Using a 27mm wrench or socket, loosen the rear axle nut.
4. Loosen the lock nuts on the drive chain adjusting bolts on both sides of the swingarm.
5. Turn both the left and right drive chain adjusting bolts an equal number of turns until
the correct drive chain slack is obtained.
Turn the drive chain adjusting bolts
counterclockwise to tighten the chain. Turn the drive chain adjusting bolts clockwise and
push the rear wheel toward the front to provide more slack. Adjust the chain slack at a
point midway between the front motor sprocket and the rear wheel sprocket. Roll the
Enertia forward, stop and place it on its kickstand. Recheck chain slack.
6.
Check the rear axle alignment by measuring the left and right side distances from the
axle block to the end of the swingarm. Make the measurement from the center of the axle
block to the end of the swingarm using the tooling hole as a reference. If the rear axle is
misaligned, turn the right or left adjusting bolts until the distances are equal.
7. Torque the rear axle nut to: 40.6 ft-lbs (55nM). If a torque wrench is not used for this
installation, see your BRAMMO Authorized Service Agent or a qualified motorcycle service
shop as soon as possible to verify proper assembly. Improper assembly may lead to a loss of
braking capacity.
8. Tighten the drive chain adjusting bolts lightly by turning them counterclockwise, then
tighten the lock nuts by holding the drive chain adjusting bolts with a wrench.
9. Recheck drive chain slack (page 63)
Chain Stretch
Your chain must be replaced when it reaches maximum stretch. Rear axle alignment
measurements of 3/8” (9.5mm) or less (as shown in the photo to the right), indicate that the
chain has been stretched to it’s maximum length, and must be replaced.
