[ST] 17/45 gearing.

I have heard several accounts of people changing to a 17/43 gearing on 
Sprints, but has anyone changed to a 17/45 gearing?  Can you retain the 
stock chain length?

This changes the final drive ratio from 2.39 to 2.65.  Based on some rough 
math (which I think was originally from a spreadsheet by Keith 'BRG' 
Tynan), this would change a 75mph cruising speed from 4700 rpm (on a 1999's 
18/43 ratio) to around 5100rpm.  Since I don't do a lot of high speed 
riding, I don't mind the loss of top speed potential.

Any thoughts?
