As usual, the engine oil change we had to go down to Hiap Aik Star Motorsport in Kapar, Klang, the ride back which take around 30+/- km, the fun factor of the RS660 is back. The valve sound is quieter compare to the previous 10W/40 grade, quick shifting was back to buttersmooth, engaging into 1st gear at the traffic light is dampen almost silent and pumping the throttle in 5-6 gear you will the get the engine feeling like a mild booster easily to 200km/h.
