Okay, thank you for the clarification. When it was 5 mph off, it was 40 mph on the speedo but 35 on the radar.
No, it doesn’t.Any stock super sport comes off the lot running at only 60% of its full potential lean fuel choked up emissions parts ect......
Yeah I just noticed the rear sprocket is +1.(43) I don't know what the front one is but I assume that's been changed too.no it's not normal to be out 12.5%
chances are you have non-stock sprocket sizes and no speedo healer.
it won't ruin anything, but your mileage will rack up faster, and your speedo is off.
