Hi there I have a 520 chain and sprocket convertion sitting at home ready to put on my R6. The question i have issssss......after i put them on my speedometer will read higher correct? which in turn will put more mileage on my bike then i actually go? Is there something that people do to make up for this or what? I know it's a common mod but do not want access mileage on my bike> It will be harder to sell one day. Thanks!
