REMARQUES CONCERNANT LA
MANIPULATION
ATTENTION:
Ne pas desserrer la vis {TPS (capteur de position
de papillon des gaz)} 1 sauf en cas de remplace-
ment du TPS (capteur de position de papillon des
gaz) en raison d’une panne, car cela provoquerait
une baisse des performances du moteur.
CONTROLE DES CONNEXIONS DES
FICHES RAPIDES ET DES FILS
1. Contrôler:
Connexion des fiches rapides et des fils
Rouille/poussière/jeu/court-circuit → Répa-
rer ou remplacer.
CONTROLE DE LA BOBINE DU TPS
1. Contrôler:

Choosing set length
1. Place a stand or block under the engine to
put the rear wheel above the floor, and
measure the length a between the rear
wheel axle center and the rear fender hold-
ing bolt.
2. Remove the stand or block from the engine
and with a rider astride the seat, measure
the sunken length b between the rear
wheel axle center and the rear fender hold-
ing bolt.
3. Loosen the locknut 1 and make adjust-
ment by turning the spring adjuster 2 to
achieve the standard figure from the sub-
traction of the length b from the length a.
NOTE:
•If the machine is new and after it is broken in,
the same set length of the spring may
change because of the initial fatigue, etc. of
the spring. Therefore, be sure to make re-
evaluation.
•If the standard figure cannot be achieved by
adjusting the spring adjuster and changing
the spring set length, replace the spring with
an optional one and make re-adjustment.
Standard figure:
90 ~ 100 mm (3.5 ~ 3.9 in)
