Correctly set the wheel's geometric data as described for the Dynamic balancing programme.
- Perform a spin.
- At the end of the spin, select the balancing programme icon
ENTER button until the required programme is selected.
- After performing a spin, when in the centred position, the video displays instructions
for where to position the balancing weights relating to the selected programme: always
to 12 o'clock if the weight is a conventional spring type or adhesive but outside the
rim, whereas for application of the adhesive weight inside the rim, use 6 o'clock as
a reference if the "LASER" configuration is active and 12 o'clock if the "H12" or CLIP
configuration is active.
- Set the wheel's rated geometric data by following the steps described in the WHEEL
DATA ENTRY chapter. If the values of the diameter and of the distance between the
balancing planes, recalculated on a statistical basis starting from the rated geometric
data of the wheel, exceed the normally accepted interval stated in the TECHNICAL
DATA section, the A5 message is displayed.
IMPORTANT: in the ALU1 and ALU2 programmes, the imbalance displayed by the ma-
chine for the outer side is with reference to the centre of gravity of the adhesive weight
aligned with the shaft assembly bearing flange, see Figure 22a.
Some minor residual unbalance may remain at the end of the spin test due to the con-
siderable difference in shape found in rims with the same nominal diameters. Therefore
change the value and position of the previously applied weights based on the configura-
tion performed in the programme "SELECTION OF ADHESIVE WEIGHTS APPLICATION
POSITION" until an accurate balance is obtained.
Motorcycle wheels can be balanced in:
- dynamic mode; when the wheel width is such (over 3 inches) to generate significant
unbalance components which cannot be eliminated with static balancing (the recom-
mended procedure);
- dynamic mode for alloy rims; a programme similar to the ALU programmes for on-vehicle
wheels, featuring the possibility of dividing the weight of one side into two parts in case
