Since I compared the speedometer with a GPS based one, we are at about 7% off. 100 kmh speed in the dash = 93 kmh gps. So I decided to match the sprocket to the true speed by taking 2 teeth off.
Ordered a JT rear steel sprocket, JTR486.41 If you look up on their website they will work for R3. Dunno about the weight compare to our sunstar one but I will weight it when I get it. Taking 2 teeth off = makes speedo overread 1% higher which is good enough for me.
