Zoran is, of course, correct. My streetbike's speedo error is due to a
change in the speedo-drive at the front wheel (long story), and not due
to sprocket changes. I need more coffee before replying to emails on
weekends, obviously. Margie: how did you determine you were showing
10mph too high? And this changed at the time you swapped sprockets? Did
you make any other changes at the same time? -W
