I have a 2005 with 52000km on the clock and she's been giving me great service. Lately I,ve started having issues with the EHCS. Sometimes she lifts the bike without any problems and other times she starts the lift ,but stops when the bike is halfway up and drops again.With my finger on the knob ,she starts to lift again and again stops about halfway up.Anyone have any idea what the issue could be?.Low hydraulic fluid maybe? Any help would be much appreciated.
