Checking chain tension
To check chain tension, turn off the engine and shift into neutral. Chain
tension is correct when the chain can just barely be pushed up to touch the
swingarm at the level of the screw
1 (see illustration). If necessary, correct
chain tension.
WARNING
–I
F CHAIN TENSION IS TOO GREAT
, PARTS WITHIN THE SECONDARY POWER TRANSMIS-
SION (CHAIN, CHAIN SPROCKETS, TRANSMISSION AND REAR WHEEL BEARINGS) WILL BE
SUBJECTED TO UNNECESSARY STRESS
, RESULTING IN PREMATURE WEAR AND EVEN
CHAIN BREAKAGE
.
–T
OO MUCH SLACK IN THE CHAIN, ON THE OTHER HAND, CAN RESULT IN THE CHAIN
JUMPING OFF THE CHAIN WHEELS
. IF THIS HAPPENS, THE CHAIN COULD ALSO BLOCK
THE REAR WHEEL OR DAMAGE THE ENGINE
.
–I
N EITHER CASE THE OPERATOR IS LIKELY TO LOSE CONTROL OF THE MOTORCYCLE
.
Correcting chain tension
Loosen hexagon nuts 2 on the left and right swingarm fists.
Loosen allan head screw
3.
Insert the hexagon socket wrench that comes with the tool set into the
hexagon socket of the eccentric and rotate the eccentric upwards
(i.e. the wheel spindle must move upwards).
!
CAUTION
!
I
F THE WHEEL SPINDLE BECOMES LOOSENED DURING THE PROCESS, RETURN ECCENTRICS
TO THEIR ORIGINAL POSITION BEFORE RETIGHTENING THE WHEEL SPINDEL
(SEE MAINTAINING ECCENTRICS)
Tighten hexagon nuts on swing arm fists to 40 Nm (30 ft.lb).
Tighten allan head screw
3 to 40 Nm (30 ft.lb).
WARNING
–D
O NOT ROTATE THE ECCENTRIC DOWNWARDS (I.E. THE WHEEL SPINDLE MOVES
DOWNWARDS
). THIS WILL RAISE THE TAIL OF THE MOTORCYCLE AND WORSEN THE
MOTORCYCLE
’
S PERFORMANCE ON THE STRAIGHTAWAY
.
–I
F YOU DON’T HAPPEN TO HAVE A TORQUE WRENCH AT HAND, MAKE SURE YOU
HAVE THE TIGHTENING TORQUE CORRECTED BY A
KTM DEALER AS SOON AS
POSSIBLE
.
Chain maintenance
For long chain life, good maintenance is very important. X-ring chains
require only modest maintenance. The best way is to use lots of water, but
never use brushes or solvents. After letting the chain dry, you can use a
special X-ring chain spray (Shell Advance Bio Chain).
WARNING
N
O LUBRICATION IS ALLOWED TO REACH THE REAR TIRE OR THE BRAKE DISK, EITHERWISE
THE ROAD ADHERENCE AND THE REAR WHEEL BRAKING EFFECTS WOULD BE STRONGLY
REDUCED AND THE MOTORCYCLE COULD EASILY GET OUT OF CONTROL
.
!
CAUTION
!
W
HEN MOUNTING THE CHAIN JOINT, THE CLOSED SIDE OF THE SAFETY DEVICE MUST
POINT IN RUNNING DIRECTION
.
Also check sprockets and chain guides for wear, and replace if necessary.
