Orange Spark 900HO 2up - 55h without any trouble, recall and first (50h) scheduled maintenance done.
My Spark came from maintenance with a weird behaviour in the OTAS system. The system was being activated with any small left input in the steering, and wasn`t being activated with any right input.
Checked the magnets and it was ok, so i cleaned the hall sensor and changed the dielectric grease in the sensor and in the connector, this seems to have solved the problem.
Hope it helps.
