USEFULL SUGGESTIONS
MULTlVAR
In several cases it operates on the revolution
gears between engine and wheels, as a gear
which has two speeds more than the original gear.
This is a great advantage in order to reach the
best engine power distribution.
MULTIVAR is sold already calibrated for engines
provided with a high power couple, but you can
set it as you like, simply replacing the rollers
included in the kit with others having diff erent
weights (always original MALOSSI).
ROLLERS - Operation
Due to the rotation the weight of the rolls
becomes centrifugal force; the higher the roll's
weight, the lower the gear change time. And vice-
versa.
Directions how to calibrate the
variator
Variator calibration
To optimize your engine's performances, adopt
rolls that in operation maintain the engine in the
highest power rotation regime. By diminishing
the rolls' weight the engine rises the RPM; on
the contrary by increasing the rolls' weight the
RPM decrease.
Spring
The pressure spring is vital to give the right
amount of load to the transmission belt which
must be balanced with the force developed by
the centrifuge masses, in relation to the kind
of engine coupling. If the belt slips, it will be
necessary to fit a spring with more load. Then
recalibrate the MULTIVAR. On the contrary if
you fit a spring with too much load, a lot of
engine power will be lost due to friction and the
transmission belt, together with the pulleys, will
be rapidly destroyed.

Multivar maintenance
Carry out checks respecting the frequency
indicated in the "Use and maintenance" manual
of the vehicle. In case of a racing use increase the
checking frequency.
Please use exclusively original Malossi spare parts.
Always demand packed and sealed products with
Malossi brand.
Please order parts with the product number that
you find on our catalogue.
Transmission belt
Check that the transmission belt isn't damaged
nor shows abnormal wear.
Pulley check
• Check that the bush does not show neither wear
nor damages.
• Check that the outer diameter of the variator
hub does not show neither wear nor damages.
• Check the wear level of the roller housings as
well as that of the belt contact surfaces.
• Check that rollers aren't damaged nor worn out.
• Check that the variator backplate sliding shoes
are not worn out.
• Check that there isn't too much clearance
between sliders and backplate.
• Check that the oil-seal does not show neither
wear nor damages.
