Gearing queation

[Pmhearns]

Has anyone changed the gearing in the other direction? Like -1 in front or +1 or 2 in the back? Im building a bobber and just gonna cruise around town, likely never get over 50 mph. I have read that uncorqing the bike gives it less resistnace to spin and allows for a slightly increaded top speed, but woukd doing that along with a lower gear imitate a gain in low end torque? Or is there simpky not enough power to turn the back wheel with more force...
