higher top speed

On the large fours with stock sprockets barely pulling redline in top gear, adding one tooth to the countershaft sprocket reduces the rpm at any given road speed (for a more "relaxed" feel) at the expense of reduced acceleration; but generally does not result in a higher attainable top road speed (likely won't pull redline with the taller gearing).

How are you primarily using the 200? If your top speed is 60, what will 70 do for you? Are you thinking about taking it on the interstate or city freeways?
