DRN'E CHAIN
The sewice life ofthe drive chain is dependent upon proper ltrbrication and
adjustment, Poor maintenance can cause premature wear or damage to the drive
chain and sprockets.
The drive chain should be checked and lubricat€d as Dart ofthe Pre-ride
inspeclion. Undersevere usage. or when Lhe molorcycle rs ndde; in unuluall) dust)
or muddy areas, more ftequent maintenance will be necessary.
INSPECTION (Fis. 44)
NOTE
By tuming the wheel, find the most tight part, where check
for slack.
Lstall the engine, place both wheels on the ground with the
motorcycle in the v€rtical position, and shift the Eansmission
into neutral.

a. l0 ^- 20 rnm
2.Check slack in the lower drive chain run midway between the sprockets.
Ddve chain slack should be adjusted to allow the followi[g vertical move-
ment by hand: I 0 - 20 mm
3.Rotate the rear wheel and then stop. Check the drive chain slack. Repeat this
procedure several times. Drive chain slack should remain constant. Ifthe chain is
slack only in certain sections, some links are kinked and binding.
Binding and kinking can fiequently be eliminated by lubdcation.
4.Insp€ct the sprocket teeth for possible wear damage. Replace ifnecessary.
s.Ifthe drive chain or sprcckets are excessively wom or damaged, they should be
replaced. Never use a new chain with wom sprockets; rapid chain wear will result.
ADJUSTMENT (Fig. 45 & 46)
Drive chain slack should be checked and adjusted, ifnecessary, every 1,000
km. When opemted at sustained high speeds or under conditions of frequent rapid
acceleration, the chain may require morc ftequent adjustment.
Ifthe drive chain requires adjustment, the procedure is as follows:
l.Loosen the adjuster ofrear brake.
2.Loosen the a,{le Dut.
3.Loosen the lock nuts for the drive chain adjusters.
4.Tum both adjusting bolts at the same time until both left and right adjusters align
with the index mark, and then reinstall the axle nut. To keep a correct concentriciry,
rctation ofboth adjusten should be identical. Chain slack should be 10^,20 mm.

LUBRJCATION
Use engine oil or a commercially prepared drive chain lubricants ill pr€fer-
ence to machine oil or other lubricants. Saturate each chain linljoint so that the
lubricant penetrates between the link plates, pins, bushings, and rollers.
R.EMOVAL AND CLEANING
men the drive chain becomes dirty, it should be removed and cleaned prior to
lubrication.
l.With the engrne off, caretully remove the chain clip.
2.Clean the drive chain in high flash-point solvent and allow it to dry. Inspect the
ddve chain for possible wear or damage. Replace any chain that has damaged
rollen, loose fitting links, or appeaN unse.viceable.
3.Inspect the sprocket teeth forpossible wear or damage. Replace ifnecessary. Never
use a new ddve chain on badly wom sprockets. Both chain and sprockets must be
in good conditioq or the new r€placement chain or sprocket will wear rapidly.
4.Lubricate the drive chain.
s.Pass the chain over the sprockets and join the ends oftbe chain with the master
link. For ease ofassembly, hold the chain ends against adjacent rear sprocket teeth
.while inserting the mast€r link.
I\WARNING
Install the chain clip so that th€ closed end ofth€ clip will face the direc-
tion of fonvard {heel rutation.
6.Adjust the drive chain and rear brake pedal free play.
CHECK AIID LUBRICATION OF CABLDS
CAUTION
Damaged flexible tube may cause corrosion inside, which affects the move-
ment ofthe cable. Check the brake cable for kinks or signs ofwear that could cause
sticking or failure. In this case th€ flexible cable should be replaced as soon as
posslole,
Lubricate the cable with a cornrnercially available cable lubricant to prcvent
premature wear and corrosion.
Contact your dealer for help if you cannot conect the problem
Recommended lubricant: engine oil Class l5W40Q
LUBRICATION OF CHOKE CABLE AND THROTTLE GRIP
To lubricate the moving part ofthe choke, remov€ the scrc% hold the end of
cable and slight pull it out, then apply few drops of lubricant to it.
rnd slight pull it out, then apply few drops of lubricant to it.
To lubricate the throttle gdp cable, fiIst disassemble the grip, then coat the
surfaces ofthrottle gip with g€neml-purpose grease.
