23.5 TIRES
The lire condition is of main importance as the sta-
bility, riding comfort. and even Ihe ride(s safety are
largely dependent on the state of the tires.
Never use 'ires with tread less than 2 mm
(.078").
An incorrect tire pressure can also affect stability
and cause rapid deterioration of the tire itself.
Correct pressures are :
Front wheel
Ol"le or two persons : 2.1 kg / em' (30 p.s.!.).
Rear wheel : - 1 person 2.4 kg / cm' (34 p.s. i.).
2 persons 2.6 kg / cm' (37 p.s.i.).
These data are intended for normal use (touring). In
case of high way or constant high speed ridi ng, in-
crease tire pressure 0.2 kg / c m' (2.8 p.s.i.).
23.6 TENSIONING THE WHEEL SPOKES - V 1000
G5
Make sure all spokes are properly tight and the
wheel perfeclly true.
• Turn the wheel by hal"ld checkil"lg with a slip
gauge for any offsets. If necessary tighten the left or
right spokes until the wheel turns freely without any
wobbling. This check should be made after the first
500 km (300 miles) and then every 1500 km (900
miles).
23.7 WHEEL BALANCING
To improve stabili ty and decrease vibrations at high
speeds, the wheels have to be properly balanced .
A good wheel balancing is obtained as follows :
• remove the wheel and set It up on a larked stand ;
• spin the wheel lightly several ti mes and watch if
it stops always in different positions. If so. the wheel
is perfectly balanced :
• if one point of the wheel always stops at the bot-
tom, put a suitable weight on the other side:
• repeat the operation until the wheel is correclly
balanced.
This check should be done after the first 500 km
and then every 1500 km (900 miles).
23.8 TIRE REMOVAL AND REFITTI NG _ V 1000 G 5
If the tires have an arrow on their sides. lit them as
follows :
• the rear wheel with the arrow turned towards the
riding direction :
• the front wheel. with the arrow turned against the
riding direction.
23.9 TIRE REMOVAL AND REFITTING - 1000 SP
This model fits light alloy rims which offer higher
mechanical resistance but may suffer damage from
110
a functional and aesthetical aspect if improper toot-
ings is used for the removal and refitling operations.
Under the circumstances. never use tools that have
ribbings or sharp edges on the side contacting the
rim.
The contacting surface of such tooling has to be
very wide, smooth, and with rounded edges. The
use of one of the lubricants available on the mar-
ket for this purpose will greatry facilitate tire sliding
and setting on the rim, preventing also overloads on
the tools.
It [s also very important for the lire beads to be pro·
perly entered into the center rim groove.
11 the tires have an arrow on their sides, fit them as
follows :
• the rear wheel with the arrow turned towards the
riding direction;
• the front wheel . with the arrow turned against the
riding direction.
23.10 CHECKING AND OVERHAULING THE
BRAKING CIRCUITS - RIGHT FRONT, LEFT FRONT,
AND REAR BRAKES (fig. 164 and 165/ 1)
1 MAINTENANCE
For a good working 01 the brakes, the lollowing in·
structions should be strictly followed :
• Periodically check the fluid level in the reservoir
for the Iront and rear master cylinders: it should ne-
ver fall below the partition in the reservoir.
• Periodically or whenever necessary top up the
fluid in the reservoirs (every 5000 km = 3000 miles
or so) . For topping up use only fresh lIuid taken from
sealed containers to be opened just before use.
• Every 15.000 km (9500 miles or so) or at least
once a year, completely renew the oit in the brake
circuits.
The Ituld Itexible pipes have to be always full and
without air; a long and elastic movement of control
levers "B .. evidences the presence of air inside the
pipes.
When cleani ng the braking circuits use only fresh
ftuld. Never use alcohol to clean or compressed air
to dry. Use : AGtP F. 1 Brake Fluid (SAE J 1703 B).
2 AIR BLEEDING FROM BRAKING CIRCUITS -
V 1000 G 5 (fig. 165)
This operation is required when the movement of
the control levers is tong and elastic because of the
presence of air inside the braking circuits.
To bteed the air, operate as follows :
Braking circuit for right front brake
• Turn the handlebar until lIuid reservoir .. A .. rea·
ches the horizontal position.
• Fill up reservoir, if necessary, taking care that
during the bleeding operation the fluid does not go
lower than the transparent section of it.
• Act on one caliper half .. F" at the time as follows :
1 remove rubber covers and fit a transparent fie·
