ATTENTION
In the clutch kit of Yamaha/Minarelli 50 engine:
inside the antagonist spring set, there are two
dust-covers in stamped plate. To fit in the new
reinforced spring set, it is necessary to take away
the external cover in order to avoid dangerous
interferences with the new spring.
ATTENTION
In the Multivar art. 51 7075 there are two
spacers: art. 08 7059B, which is 2 mm thick and
art. 0811670B, which is 5 mm thick
The art. 0811670B, which is thicker, must only
be fitted to Malaguti F12 LC having a fanned
crankcase made from the year 2000 onwards,
whilst the first one, which is 2 mm thick, must be
fitted to all the other scooter models.
