CARBURETOR CHOKE
This model's choke system uses a fuel enrichening circuit con-
trolled by a choke valve. The choke valve opens the
enrichening circuit via a cable when the choke lever on the
handlebar is pulled back.
Check for smooth upper choke lever operation. Lubricate the
choke cable if the operation is not smooth.
Remove the left and right choke cable boots from the choke
valve nuts.
Loosen each choke valve nut and remove the choke valve from
the carburetor.
Push the choke lever on the handlebar all the way up to fully
closed and measure the distance between the ends of the
choke valve and nut.
It should be 10-11 mm (0.39-0.43 in).
Adjust the distance to within specifications by loosening the
lock nut and turning the cable's elbow at the left handlebar
switch housing.
Tighten the lock nut securely and recheck the distance.
Thread the choke valve in by hand and then tighten the choke
valve nut 1/4 turn with a 14 mm wrench.
