hey guys will droping a tooth on the front sprocket mess with the correct mileage reading, i no it does on the speedo, dont no if this subject has been brought up just curious to no
wow i didnt no that, i new that i couldnt put that many miles on the bike in a yr but i did raise my final drive ratio up by 33% over stock making it now 3:00 gear ratio now, stock is 2.67The more that you increase the final drive ratio, the more that the speedo and odometer will be off.
With a -1/+2 sprocket change, you are now pretty far off from the stock gearing. Your odometer will read more miles than you have actually gone.
Edit: This is a good reason to buy a speedohealer. If you change you sprocket combo by 10% from stock, you will show 10 extra miles for every 100 miles that you ride.
