Adjusting the carburation and
idling speed (hand adjustment)
(fig. 28)
Proceed as follows:
Warm the engine up to its normal running
temperature.
2 Screw in fully idling adjusters " E" .
3 Check with your hands if the exhaust pipe
pressures are equal. If necessary, act on screw
"D" of one carburettor until the exhaust pressu-
res of both carburettors are the same (idling
speed should be kept at no more than 900-1000
rpm and consequently it may be necessary to
screw in the screw of the carburettor for the cy-
linder giving a lower exhaust pressure , or screw
out the screw of the carburettor for the cylinder
giving a higher exhaust pressure) .
4 Acting on screws " E" get the best carbura-
tion for each cylinder (this is perceived by an
increase of rpm) and then ad j ust idling speed
according to point 3.
5 Disconnect one spark plug lead at the time
and check that in both cases the engine stops
after firing 5-6 strokes. If it does not , screw out
screw " D" of the carburettor making the engine
fire more than 5-6 stroke or screw it in for the
carburettor making the engine f ire less than 5-
6 strokes.
6 Adjust idling speed at 900-1000 rpm by screw-
ing or unscrewing both screws "D" by the same
amount.
7 With the throttle grip closed, ensure there is
a clearance of 1-1.5 mm (.039-.059") between ca-
ble ends and cable adjuster screws "F"of both
carburettors.
8 Ensure that the throttle valves open simulta-
neously by proceeding as follows : gradually turn
the throttle control grip and check that the exh-
aust pipe pressure increases in synchronization
with your hands (an assistant is necessary for
this operation).
If pressure increase of one cylinder is advanced,
act on its carburettor by gradually screwing in
cable adjuster "F", after loosening conternut " G",
until the synchronization of both exhaust pipes
pressure is reached.
