68 Servicing and Maintaining Your Empulse
It is recommended you repeat the measurement several times to get
an average value for the chain deflection in case there are any tight
spots on the chain.
Inspect the drive chain for:
• Damaged rollers
• Dry or rusted links
• Excessive wear
• Improper adjustments
Replace the drive chain if it has damaged rollers, loose pins, or kinks
that cannot be freed. Lubricate any kinked or binding links and work
them free. Adjust chain slack if needed.
Inspect the front motor sprocket and rear wheel sprocket teeth for
excessive wear or damage. If necessary, have your Brammo
Authorized Dealer replace a worn sprocket.
Adjustment
1. Place the Empulse on a rear wheel stand with the ignition switch
in the Off position.
2. Using a 27 mm wrench or socket, loosen the rear axle nut.
3. Loosen the lock nuts on the drive chain adjusting bolts on both
sides of the swingarm.
4. Turn both the left and right drive chain adjusting bolts an equal
number of turns until the correct drive chain tension is obtained.
• Turn the drive chain adjusting bolts clockwise to tighten the
chain.
• Turn the drive chain adjusting bolts counter-clockwise and
push the wheel forwards to loosen the chain tension.
Check the chain tension at a point midway between the front
motor sprocket and the rear wheel sprocket. Move the Empulse
forward and recheck the chain tension.
