Coolant replacement
Coolant shall be replaced with cold engine and coolant.
- Remove the engine guard as indicated under the relevant paragraph.
- Place a vessel on the R.H. side of the cylinder, under the coolant drain screw
(1). FIRST remove the screw (1) then SLOWLY open the L.H. radiator cap
(2); slope the motorcycle on the right side to drain the coolant easily in the
vessel. Reassemble the screw (1).
To fill in the system, set motorcycle on a central stand, or in any case
keep the bike in a vertical position (not on the side stand).
- Pour the necessary quantity of coolant in the radiator then warm up the en -
gine in order to eliminate any possible air bubbles.
- Allow the coolant to cool down then remove cap (2) and check the level as
explained under “Coolant level check”.
- Periodically check the connecting hoses (see “Scheduled Maintenance
Chart”): this will avoid coolant leakage and consequent engine seizure: If
hoses (A) show cracks, swelling or hardening due to sheaths desiccation,
their replacement shall be advisable.
- Check the correct tightening of the clamps (B).
