Thanks for your reply.  In this case, I think there might be an
accuracy problem, depending on the type of mechanism used.  If
the speedometer uses a spiral or coil return spring to counter-
balance the cable-generated force moving the needle, then the
reading may not be linear at the extreme end of the needle 
movement.  

[Of course, if accuracy was really important, you could get 
someone to perch up on your handlebars with a bottle of white-out 
and mark the new speed indications as you increase speed from
85mph to 130+mph. :-) My officemate has volunteered to perform 
this service, should you wish to try this out.]

Actually, you could do the same thing with a power drill attached
to the speedo cable.  However, before you start tearing up your
speedometer, wait a few days:  A friend of mine has found an
advertisement in an old "Rider" magazine which purports
to provide accurate OEM speedometer guts with new meter faces
for popular models.  If it pans out, I'll post it.

Again, thanks for the help,
