grazie Nano! i dettagli a pag.81:

Repairs to the engine’s ’top-end’ are free during the Event. All interventions to the ‘bottom-end’ (inside the main engine cases) will be considered as a change of engine.
Once removed and replaced by engine B, the refitting of engine A into the Machine will be considered as a change of engine, in the same way as replacement by engine C.

The change of engine will incur a penalty:
the first change : 15 minutes,
the second change : 45 minutes
all following changes : 2 hours for each change.

The change of engine between Riders is allowed during Marathon Stages. The penalties will be applied to both Riders.

quindi mi rispondo da solo: sì, Coma si fa tutta la Dakar con un motore solo.....estik@zzi
