D. Cable Inspection and Lubrication
The throttle twist grip assembly should be
greased when the cable is lubricated, since the
grip must be removed to get at the end of the
throttle cable. Two screws clamp the throttle
housing to the handlebar. Once these two are
removed, the end of the cable can be held
high to pour in several drops of lubricant.
With the throttle grip disassembled, coat the
metal surface of the grip assembly with a
suitable all-purpose grease to cut down fric-
tion.
1. Damage to the outer housing of the
various cables may cause corrosion.
Often free movement will be obstructed.
An unsafe condition may result. Replace
such cables as soon as possible.
2. If the inner cables do not operate
smoothly, lubricate or replace them.
Recommended lubricant:
Yamaha Chain and Cable Lube or
10W30 motor oil
E. Brake and Change Pedals/ Brake
and Clutch Levers/Sidestand
Lubricate the pivoting parts of the lever,
pedal, and sidestand.
Recommended lubricant:
Yamaha Chain and Cable Lube or
10W30 motor oil
F. Drive Chain
Drive Chain Tension Check
Inspect the drive chain with both tires
touching the ground and with rider on the
seat. Check the tension at the position shown
in the illustration. The normal vertical deflec-
tion is approximately 60 - 70 mm (2.4 - 2.8
in). If the deflection exceeds 60 - 70 mm (2.4
- 2.8 in), adjust the chain tension.

Drive Chain Tension Adjustment
a.60-70mm(2.4-2.8in)
1. Loosen the rear brake adjust nut.
2. Loosen the rear wheel axle nut.
3. Loosen the adjust bolt locknuts on each
side. To tighten chain, turn chain puller
adjust bolts clockwise. To loosen chain,
turn adjust bolts counterclockwise and
push wheel forward. Turn each bolt ex-
actly the same amount to maintain cor-
rect axle alignment. (There are marks on
each side of rear arm and on each chain
puller; use them to check for proper
alignment) .
Drive chain slack:
60 - 70 mm (2.4 - 2.8 in)

Before adjusting, rotate rear wheel through
several revolutions and check tension several
times to find the tightest point. Adjust chain
tension with rear wheel in this "tight chain"
position.
4. After adjusting be sure to tighten the
locknuts and the rear wheel axle nut.
