I'm interested in doing this mod when the original sprockets are worn but what about speedometer accuracy. I went to a larger counter shaft sprocket on my Triumph Tiger 1050 to reduce rpm's at cruise speed. This mod had the added benefit of making the speedometer dead on where as before it had been a bit optimistic. The CB1100's speedometer is quite accurate with stock gearing. Does the change in gearing have an effect on the speedometer's reading? If the speed sensor is located at the front wheel there's no problem but most bikes have the sensor located to measure speed at the counter shaft sprocket.
