Adjustment Of The Clutch Control Lever; Spark Control; Correct Heat Rating - Husqvarna 2013 CR 125 Owner's Manual

ADJUSTMENT OF THE CLUTCH CONTROL LEVER

To adjust the clutch control lever, you will need to adjust cable
tension using the adjuster on the lever.
- Shift the rubber protection (1).
- Work on the adjuster screw (2), turn it in the direction indi-
cated by the arrow (A) to decrease clearance, turn it in the
direction indicated by the arrow (B) to increase it.
There should be at least 10 mm (0.39 in.) free play (V) before
the clutch begins to disengage.
The adjustment can be also effected with tightener (3) set on the
left of the frame. Take care to tighten properly the lock nut. If
the clutch slips under load or drags in disengaged position after
play has been adjusted, it must be taken apart for inspection.

SPARK CONTROL

Use NGK BR9EG or CHAMPION QN84; spark plug (2); the gap
is 0,6 in.
A wider gap may cause difficulties in starting engine and in
overloading coil.
A gap that is too narrow may cause difficulties when accelerat-
ing, when idling the engine or when performing at low
speeds.
Clean the dirt away from the base of the spark plug before re-
moving it from the cylinder after removing the cap (1).
It is very useful to examine the state of the spark plug just after it
has been removed from the engine since the deposits on the plug
and the colour of the insulator provide useful indications.

Correct heat rating:

The tip of the insulator should be dry and the colour should be light
brown or grey.
High heat rating:
In this case, the insulator tip is dry and covered with dark deposits.
4
Low heat rating:
In this case, the spark plug is overheated and insulator tip is vitre-
ous, white or grey in colour.
CAUTION*: Select a spark plug with a colder or
hotter heat range carefully and cautiously. A
spark plug with too hot a heat range may lead
to preignition and possible engine damage. A
V
spark plug with too cold a heat range may foul
as the result of too much carbon buildup.
Before refitting the plug, thoroughly clean the
electrodes and the insulator using a brass-met-
al brush.
Apply a little graphite grease to the spark plug
thread; fit and screw the spark plug by hand
then tighten to the torque of 23,5÷25,5 Nm-
17,3÷18,8 ft/lb.
Spark plugs which have cracked insulators or
corroded electrodes should be replaced.
