cable stretch or maladjustment, the excessive play in
the throttle grip will cause a delay in throttle response,
which will be especially noticeable at low rpm. Also, the
butterfly valves may not open fully at full throttle. On
the other hand, if the cables are too tight, the throttle
will be hard to control, and the idle speed will be erratic.
To check the throttle cable adjustment:
-check that there is 2 -- 3 mm throttle grip play.
ePush the throttle grip completely closed. At this time
there should be no clearance between the cable bracket
and the stop.
NOTE: This assures that the stress of throttle grip
return will be taken by the pulley, protecting the car-
buretor linkage mechanism.

To adjust the throttle cables:
If anyone of the above checks shows improper
adjustment, adjust the throttle cables as follows:
eLoosen the locknuts, and screw both throttle cable
adjusting nuts in fully at the upper end of the throttle
cables so as to give the throttle grip plenty of play.
eTurn out the decelerator cable adjusting nut until there
is no clearance between the cable bracket and the stop
when the throttle grip is completely closed. Tighten

If the throttle cables cannot be adjusted by
using the cable adjusting nuts at the upper end of the
throttle cables, use the cable adjusters at the lower
ends of the throttle cables. Do not forget to securely
tighten the adjuster mounting nuts.
If grip play is adjusted too large, the butterfly valves
may not open fully at full throttle. To check this,
check to see that the pulley stops against the stop
pin on the carburetor body when the throttle grip
is fully turned.
