    16T sprocket question

    Fitted 16t and did the Speedo DRD today. The gearing calc was around 5.8% out but the actual error according to my GPS was 10.8% - so about 5% speedo error from Yamaha. I programmed 10.8% into the Speedo DRD and it is spot on. Too early to tell on fuel use but 16t does make the bike a lot...
