Smaller front sprocket and driveability

[OB_gsx1300rguy]

Hey it looks like the one tooth down thing is pretty popular.I have some questions to the guys that did it.How much rpm does this add to cruising speed say 80mph (750)? Did you have to put in a different chain?Gas mileage? Was it worth it? No I`m not a 1/4 mile guy .Just like big accelleration.

Here you go, all are 6th gear speeds in mph:
RPM STOCK -1
4000 72.9 68.6
5000 91.1 85.8
6000 109.4 102.9
7000 127.6 120.1
8000 145.8 137.2
9000 164.0 154.4

I went -1 on the front and +3 on the rear, you could say it was a bit much, but shure has changed the way the bike accelerates.
