CLEANING
- STORING
return to contents
Cleaning
Preparations
for washing
Before washing the
vehicle the following parts should be covered with an impermeable material:
the rear part of the silencers; the clutch and brake levers and pedals,
the throttle twist-grip and the ignition key switch.
Washing
Avoid spraying water
too much pressure on the instru-
ments and the front
and rear hubs.
Drying
Remove the protective
coverings.
Thoroughly dry the
vehicle.
Test the brakes
before using the vehicle.
N.B. - To clean
the painted parts of the engine unit
(engine, gearbox,
transmission box, etc.) the fol-
lowing products
may be used: diesel oil, petrol or
water-based neutral
detergents for car cleaning.
These products
should be washed off immediately
with water; do
not use waterat high temperatures or
pressures.
Storage
If the vehicle is
to remain idle for a considerable period
of time (e.g. for
the winter period) it should be stored in
the following way:
- clean the vehicle thoroughly;CLEANING THE WINDSCREEN (if mounted)
- empty the f uel tank and the carbureftors; if left for-a
long time, the fuel would evaporate;
- remove the spark plugs and put a few drops of SAE
30 oil into che cylinder. Turn the crankshaft for a few
revolutions and then replace the spark plugs;
- reduce the tire pressures by 20%;
position the vehicle so that its wheels are not
touching the ground;
- smear a layer of oil on unpainted parts to prevent
rust;
- remove the battery and store in a dry place away
from the direct sunlight andwherethere is notdangerof
frost; check the battery charge once a month;
- cover the vehicle but in such a way that the air can
circulate.
The windscreen can
be cleaned using most of the
soaps, cleaners,
waxes and polishes commercially
available for glass
and plastic.
The following precautions
should be taken:
- do not wash or polish the windscreen in direct or
strong sunlight or when temperatures are high;
- under no circumstances use solvents, lyes or similar
products;
- do not use abrasive substances, pumice, sand/
emery paper, files, etc.;
- wash all dust and dirt away before polishing. Small
superficial scratches can be removed using a mild
polish;
- paint or sealing compound can be removed before
harden by using diesel, isopropylic alcohol or butyl
cellosolvent (do not use methyl alcohol);
- use soft cloths, sponges, chamy leathers or cotton
wool; do not rub too hard. Do not use paper towels or
man-made fibre cloths as they tend to scratch the
windscreen.
- Deep scratches cannot be removed by hard rubbing or
the use of solvents.

Preliminary checks
Check:
- that there is sufficient fuel in the tank;
- that the engine oil level in correct;
- the ignition key is in position <<A>> (see fig. 3);
- that the following warning lights are on;
- red warning lights: oil pressure and generator;
- green warning light: <<NEUTRAL>> indicator;
- that the <<CHOKE>> control is in the starting position
(if the engine Is cold) (<<1>> fig. 4).
Cold start
Once the preliminary
checks are complete the vehicle
can be startted.
Turn the throttle twist-grip until it is 1/4
open, disengage
the clutch fully, check that the switch
<<B>> (fig.
5) is in the run position; press the starter button
<<C>> (fig.
5).
When the engine
has started, allow the engine to idle at
low revs for
a few minutes (in cold weather) or for a few
seconds (in warm
weather) before switching the
<<CHOKE>>
control to the run (off) position (<<2>> in fig.
4).
If the <<CHOKE>>
is left in the start position (<<1>> fig. 4)
when the vehicle
is being used, carburation will
be faulty,fuel
consumptionwill begreatly increased
and there will
be a risk of seizing the engine caused
by the washing
of the cylinders by the excess fuel.
Caution!
-
If the green <<Neutral>> warning light does not
come on when the
ignition switch is on (see <<A>> in fig. 3)
this means that
a gear is engaged; starting the vehicle
in this condition
could be dangerous.
Before starting,
always check that the engine is in
neutral.
Warm start
Follow the same
procedure as that for the cold start but
without the <<CHOKE>>
control in the start position
(<<1>> fig.
4) otherwise the mixture will be too rich.
ATTENTION!
-
The
starter motor should not be
operated for
more than 2-5 seconds; if the engine
doesn't start,
wait for 10 seconds before the following
starting operation.
Anyway act on the starter button
(START) only
with the engine completely stopped.
On the road
To change gear,
shut the throttle, disengage the clutch
fully and engage
the next gear; then engage the clutch
gradually while
opening the throttle.
The gear change
pedal should be operated firmly and
surely.When changing
down use the brakes gradually
and close the throttle
gradually to avoid over-revving the
engine.
Stopping
Close the throttle
and use the brakesjust as the vehicle
is about to stop
disengage the clutch. These three
operations should
be carefully coordinated to maintain
full control of
the vehicle.
When slowing down
in normal conditions, use the
gearbox to provide
engine braking to slow the vehicle;
take care not to
over-rev
the engine. Use the brakes
(especially the
right front brake) with particular care
when roads are slippery
or wet.
To stop the engine,
turn the ignition switch until <<O>>
(see fig.
3).
in the model
with carburetors, do not forget to turn
off the fuel
taps.
Parking
On badly lit roads,
leave the parking lights on.
Turn the ignition
switch until <<B>> (see fig. 3); turn the
light switch <<A>>
(fig. 5) to position ,<<P>>; remove the
ignitionand lockthesteering
(see <<Steering lock>> fig. 13).
RUNNING-IN
return to contents
The recommendations
below should be followed when
running-in:
- Before riding,
run the engine at low revs until it has
warmed up.
- Do not exceed the
rpm shown in the table; it is also
advisable to run
the engine at varying speeds rather
than at a constant
speed.
- Before stopping
reduce the speed gradually to avoid
subjecting components
to sudden changes in tempera-
ture.
- Remember that components
need several thousand
kilometers before
they are properly bedded in; care
taken in this period
will ensure prolonged vehicle life.
After the first
500~1500 km
- Change the engine
oil.
Should the oil
level drop to the minimum level
before the first
500+1500 kilometers have been
completed then
carry out a complete oil change
rather than just
topping up. Recommended oil:
-Agip 4T SUPER
RACING SAE 201&150-~
- Check that all nuts and bolts are tightened.
- Check rocker clearance.
- Check the ignition timing.
- Check tire pressures.

MAINTENANCE
AND ADJUSTMENTS
return to contents
Adjusting the clutch lever (fig. 15)
There should be 3~4
mm of free play at the lever; turn
the adjuster screw
<<A>> to obtain the desired play.
Play can also be
adjusted on the cable adjuster <<B>>
located on the right
side of the gearbox. First loosen the
lock nut <<C>>
and then adjust.
Adjusting the
front brake lever (fig. 16)
There should be
a certain clearance between the pump
float and the tip
of the control lever. This play can be
adjusted by turning
adjustment screw <<C>>.
Checking brake
pad wear
Check brake pad
thickness every 3000 mi. (5000 km):
- new pads 0.35
in. (mm 9);
- wear limit approx.
0.24 in. (mm 6).
If the pads are
below the wear limit they should be
changed. It is not
necessary to bleed the brakes when
new pads have just
been f ifted; pumping the brake lever
a few times will
return the caliper pistons to their normal
position.
When changing the
pads also check the flexible hoses;
if damaged they
should be replaced immediately.
N.B. - Treat new
brake pads with moderation for the
first 60 mi.
(100 km) until they are properly bedded in.
Checking brake
disks
The brake disks
must be perfectly clean, with no oil,
grease or other
dirt on them. They should also show no
signs of scoring.
The torque wrench
setting of the screws that fix the disk
to the hubs is 2.21~2.46
ft. lbs. (3~3.2 kgm.)
Checking and changing
the brake
fluid in the
master cylinder reservoir
(figs. 16
& 17)
To ensure efficient
operation of the brakes:
1 Make frequent
checks of the fluid level in the front
(<<A>> in
fig.
16) and rear (<<H>> in fig. 17) reservoirs.
The
level should always
be above the <<Minimum>>, mark on
the reservoirs.
2 Top up
the brake fluid when necessary or at regular intervals.
Only use recommended
brake fluid in sealed containers
for topping up.
Fluid
containers should only unsealed
a moment before
they are about to be used.
3 The fluid
in the brake should be changed completely
every 15.000 km
or at least once a year.
To ensure efficient
braking there should be no air
bubbles in the brake
circuit; long lever travel, or a
spongy brake lever
response indicates that there are air
bubbles in the brake
circuit.
When flushing the
circuit only use fresh brake fluid.
Never use alcohol
for flushing or compressed air
for drying; we
recommend trichloroethylene for
metal parts.
Never use mineral
oils or greases for lubricating parts;
if no suitable lubricant
is available then rubber and metal
parts can be lightly
greased with brake fluid.
Recommended brake
fluid:
<<Agip brake Fluid - DOT4>>.
These operations
are best carried out by a Moto-Guzzi dealer.
Adjusting the brake pedal of rear and left-hand front brakes (fig. 17)
Check the play between
the master cylinder actuator
and the brake rod
as follows:
- place a feeler
gauge <<G>> between the cylinder actuator
and
the brake rod, the gap between the two
parts
should be 0.05~0.15 mm.
Turn
the eccentric screw <<A>> to obtain the desired gap;
- If the gap is
not correct, remove the split pin, remove
the
pin, unscrew the lock nut <<B>> and then screw or
unscrew
the fork <<C>> to obtain the desired position for
the
brake pedal <<F>>; replace the brake rod retaining pin
and
the split pin.
Now
undo the lock nut <<E>> and adjust the lever return
stop
screw <<D>>.
Bleeding the brake
system
The brake system
requires bleeding when there are air
bubbles in the system
and when the travel of the brake
pedal and lever
becomes long and spongy.
This operation
is best carried out by a Moto-Guzzl dealer.
Adjustable telescopic fork (fig. 18a and 18b)
This motorcycle is
equipped with a new hydraulic tel-
escopic fork MOTO
GUZZI with separate adjustment of
springs pre-loading
and of dampers operation. To ad-
just springs pre-loading,
turn nut <<A>> through a 32 mm
wrench. Turning
it clockwise the spring pre-loading is
reduced; turning
it counterclockwise, the pre-loading
increases.
To adjust the damper
hydraulic operation, turn knob
<<B>>.
Turn it clockwise,
the hydraulic operation decreases;
turning it counterclockwise,
it increases.
Do not force
the knob <<B>> and the nut <<A>> to the
extreme positions.
N.B. - It's Important
that spring pre-loading and
damper operation
are equally adjusted on both
forks prongs,
(equally turn both pre-loading ad-
justment nuts,
beginning from end of stroke posi-
tion, as well
as the two hydraulic operation adjust-
ment knobs).
To avoid the
damaging of the shock-absorbers
when riding on
uneven roads, do not adjust them
(knob <<B>>)
In position of maximum braking.
Adjusting the rear shock absorbers (fig. 19)
The motorcycle is
equipped with shock absorbers with
separate adjustment
of the springs pre-loading and the
action of the dampers.
To adjust the springs
pre-loading, turn ringnut <<A>>
manually.
Rotating in a counter-clockwise
direction (looking down
from above) the
preloading of the springs is increased;
vice versa, rotating
in a clockwise direction, it isreduced.
To adjust the hydraulic
braking of the suspension, turn
adjustment control
knob <<B>>.
According to needs
and the load on the motorcycle,
there are several
setting positions; from position <<1>>
very soft (minimum
damping) to position <<5>> very hard
(maximum damping).
The filling and
operating pressure of the rear shock
absorbers is 72.5~101
psi. (5~7 BAR), to be checked using the correct
gauge; for filling,
use nitrogen or dehydrated air.
The shock absorber
pressure should be checkedby an
authorized Moto-Guzzi
dealer.
N.B. - Each shock
absorber should have the same
spring loading
and damper setting as the other
shock absorber
to ensure maximum stability of the
vehicle.
Adjusting the steering (fig. 20)
To ensure safe riding,
the steering should be adjusted
to allow free movement
of the handlebars without any
play.
- Remove bar locking plate <<D>>.This operation is best carried out by a Molo-Guzzi
- loosen the steering head fixing bolt <<A>>;
- undo the steering head nut <<B>>;
- turn the adjuster nut <<C>> to take up any play.
When play has been adjusted tighten the nut <<B>> and
the steering head fixing bolt <<A>>.
REMOVING
THE WHEELS
return to contents
Front wheel (fig. 21)
Remove the wheel as follows:
- place the machine securely on its centre stand,INSTRUCTIONS FOR VEHICLES EQUIP-
place a support underthe engine base in orderto lift the
wheel from the ground;
- undo the bolts <<A>> holding the brake calipers to the
fork legs and remove the calipers complete with hoses;
- unscrew the spindle retaining wheel nut <<C>>;
- loosen the pinch bolts ,<<E>>
- remove the wheel spindle <<F>> paying attention to
the position of the spacers<<D>> then remove the wheel;
- refitting the wheel is the reverse of the above proce-
dure; care should be taken to fit the spacers in the
correct position; pump the brake lever and pedal a few
times to return the caliper pistons to their normal posi-
tion.
At each maintenance
control, check for integrity and
tension of the wheel
spokes.
A wrong spoke tension
or the breakage of one or more
spokes may affect
the wheel, thus compromising the
vehicle safety and
stability.
Always observe the
maximum load indications provided
on the official
circulating papers.
Rear wheel (fig. 22)
To remove the rear
wheel from the swinging arm and
from the final drive
box proceed as follows:
- place the machine securely on its centre stand;Refitting the wheel is the reverse of the above procedu-
- remove the left side silencer;
- undo the spindle nut <<A>> and washer <<B>>on the
final drive box side;
- loosen the pinch bolt <<D>> on the swinging arm;
slide the spindle <<C>> out from the final drive box, the
hub, and the swinging arm;
- remove the plate assembly complete with caliper
<<E>> from the torque arm and fix this assembly to the
frame;
- lean the machine to the right just enough to be able
to disengage the wheel from the swinging arm and the
final drive box and remove.
Wheel
balancing
To improve stability
and decrease vibrations at high
speed, the wheels
must be well balanced.
This operation is
best carried out by a Moto-Guzzi dealer.
TIres
TIres are among
those machine components which
require regular
checking.
Machine stability,
rider comfort and safety all depend on
good tIre condition.
Do not use tires
with less than 0.08 in. (2 mm) of tread.
Incorrect tire pressures
can cause instability and ex-
cessive tyre wear.
Tire pressures:
- ront wheel: with one or two riders 33.36 psi. (2.3 BAR.)These pressures are for normal touring use. For
- rear wheel: with one rider 36.26 psi. (2.5 BAR)
- rear wheel: with two riders 42.06 psi. (2.9 BAR)
Tire fitting
This machine isfitted
with cast, aluminum alloy rims; even
though these are
very strong they can be damaged both
aesthetically and
mechanically by the use of incorrect
tools when removing
and fitting tyres. Tyre levers should
not have sharp edges
or ribbing in those places where
they come into contact
with the rim; lever contact
surfaces should
be smooth and edges should be
rounded.
Use of a suitable
commercially available lubricant facili-
tates tyre removal
and fitting therefore making strenu-
ous use of the levers
unnecessary. It is important to
ensure that the
tyre beads settle properly into the centre
rim groove.
Some tires have
an arrow molded on the sidewall, in
these cases the
tires should be fitted as follows:
- rearwheel: arrowpointing in thedirection of rotation;
- front wheel: arrow pointing against the direction of rotation.
N.B.-These
instructions should befollowed unless
otherwise directed
by the tyre manufacturer.

Battery maintenance
Batteries which
are already in service (i.e. dry batteries
which have been
filled, activated and charged) should
be maintained as
follows:
- top up with
distilled
water (never use acid) so that
the
liquid level is 0.2 in. (5 mm) over the top of the plates;
- battery terminals
should be kept tightened,
clean
and greased with Vaseline;
- keep the top of
the battery clean, avoid spillage of
electrolyte
as this will reduce insulation and will corrode
the
battery holder and cover;
- check that the
charging equipment is not under or
overcharging
the battery; battery liquid specific gravity
should
be 1.24+1.27. If this is not the case it will be
necessary
to check the insulation and efficiency
of
charging and starting equipment;
- batteries which
are stored should be charged at
regular
intervals at 1 /1 Oth of capacity, should be kept
topped
up and with a specific gravity of 1.27 at 25°C;
- the battery should
be clamped firmly in place com-
plete
with anti-vibrations devices.
N.B. - In tropical
climates (average temperature
above 330C) electrolyte
specific gravity should be
reduced to 1.23.

GENERAL
The use of a injection-ignition
system with electronic control in the Otto
engines makes possible
a optimal use of them, with a larger specific power,
a lower specific
consumption and the minimum quantity of unburnt
elements in exhaust
gases.These advantages have been obtained by a more
correct ratio between
air and fuel and by a optimal use of the ignition
advance.

WEBER injection-ignition
system (I.A.W.)
In the Weber injection-ignition
system type <<alfa/N>> the
engine speed and
the throttle position are used to
measure the quantity
of sucked air; when the quantity of
air is known, measure
the fuel quantity in relation with
the desired strength.
Other sensors in the system allow
to adjust the main
operation, on particular condition.
Moreover, the engine
speed and the throttle angle allow
to calculate the
optimal ignition advance on every
operation condition.
The quantity of air sucked from
each cylinder per
cycle, depends on the air density in
the suction manifold,
on the single displacement and on
the volume efficiency.
The volume efficiency is experi-
mentally calculated
on the whole operation field of the
motor (rpm and engine
load) and is stored in the
electronic unit.
The control of the injectors, each cylin-
der, is <<time-sequenced>>,
i.e. the two injectors are
controlled on the
basis of the suction sequence while
the delivery can
already begin, for each cylinder, from
the expansion phase
until the suction phase, already
begun. The timing
for the initial delivery is contained in
the electronic unit.
The ignition is of static inductive
exhaust type with
the dwell check on the power module
and the advance
curves, stored in the electronic unit.
The coil-power module
unit receives the I.A.W. control,
that processes the
ignition advance.
Description of
the system
Fuel circuit
The fuel is injected
along the suction pipe of every
cylinder, in the
upper side of the suction valve.
It includes: tank,
pump, filter, pressure adjuster,
electroinjectors.
Sucked air circuit
The circuit includes:
air filter, suction pipe, floated
casing.
Downstream the throttle
valve is installed the plug for
the pressure adjuster.
The potentiometer
for the throttle position is assembled
on the throttle
shaft.
The max. pressure
sensor and the air temperature
sensor are installed
upstream the throttle valve.
Control circuit
With this circuit,
the electronic unit detects the engine
conditions and the
performance of the fuel exhaust and
the ignition advance.
It includes: battery,
ignition switch, two relais, electronic
unit, ignition unit,
max. pressure sensor, air temperatu-
re sensor, throttle
position potentiometer, two injectors,
oil temperature
sensor, revolutions counter and phase
counter.
Operation phases
Normal operation
When the engine
is in standard thermic conditions, the
I.A.W. unit counts
the phase, the injection time, the
ignition advance,
only by interpolation on the corre-
sponding stored
presettings, upon the number of
revolutions.
The quantity of
fuel, calculated in such way, is delivered
at once, in a sequencial
way to the two cylinders.
The count of the
initial delivery moment, for each
cylinder, is made
by means of apresetting that depends
on the number of
revolutions.
Starting phase
When the ignition
switch is in operation, the I.A.W. unit
feeds thefuel pumpforfewtime
and detects thethrottle
angle and the temperature
of the engine.
After starting the
engine, the unit receivesthe revolution
and phase signals,
which allow it to control the injection
and the ignition.
To make the starting
phase easy, an enrichment of the
main quantity, upon
the oil temperature, is performed.
After the starting
phase, the unit begins the check of the
advance.
Acceleration operation
During acceleration,
the system increases the delivered
fuel quantity, in
order to obtain the best way of guide.
This condition is
detected when the throttle angle vari-
ation reaches appreciable
values, the enrichment factor
is determined upon
the oil and air temperatures.
Fuel cut (CUT-OFF)
The release of the
accelerator, on high rpm conditions,
is detected by the
unit as deceleration intention; therefore,
it is possible,
both for increasing the efficiency of the
engine brake and
for reducing the consumption, to
eliminate for a
given period of time the fuel delivery.
This condition is
detected by means of the throttle
position potentiometer
(throttle closed) and of the number
of revolutions.
WARNING!
In order not
to cause damages to the electronic
Ignition system,
follow the precautions hereunder:
- in case of
battery removal or refitting, be sure
that the Ignition switch Is In position <<OFF>>;
- do not disconnect

Fuel filter replacement (<<A>> fig. 37)
The filter is provided
with a filtering element made of
paper, with 186
sq. in. (1200 CM2 surface), and 0.35 oz. (10 gm)
filtering power:
it is necessary due to the high sensibility of injectors
to foreign elements.
The filter is assembled
under the fuel tank between the
pump and the pressure
adjuster and on the external
cover there is an
arrow showing the direction of the f uel.
Every 6000 mi. (10.000
km) it is necessary to replace it.
For the cartridge
replacement, apply to a Moto-Guzzi dealer.
