I havn't seen anybody talk about tire size which can have a very
difinite
effect on speedo error and correct top speed. Look at any tire chart and
you will see a big difference in tire circumference with the tires sizes
very close together if not the same size. Don't forget to take this into
consideration. Does anyone one out there have the formula for determining
top speed using tire circumference, axel ratios, and rpm's?
