Using a 13 tooth front and 51 rear, my YZ426F tops out at around 63 MPH. Does anyone know the difference I will see with a 14 tooth front sprocket?

Without doing the math I would estimate about a 7-8% increase in top speed. 14/51 is still lower gearing than stock...14/49 is stock, at least on the '02.

7-8% would be about right. Roughly a 6 mph increase.
