D3) ROTOR ENGAGEMENT BELT
The rotor engagement belt should only be replaced and adjusted after having first replaced
the forward belt( point D2)
Remove the belt (Fig. 12 Ref. A) turning the engine pulley (Fig. 12 Ref. C) anticlockwise. Fit
the new belt by slipping it onto the large pulley (Fig. 12 Ref. B) first, then onto the engine pulley
(Fig. 12 Ref. C). Then switch on the engine, making sure that the rotor engagement lever
(Fig. 1 Ref. D) is released and that in this condition the belt does not work. Should the belt
engage remove the pulley support screws (Fig. 14 Ref. A and B) and move the pulley support
towards the machine handlebars. Then retighten the screws and adjust the rotor brake (Fig.
7 Ref. C).
