The most common switch seems to be going slightly taller gearing, either changing the front sprocket to a 15-tooth (from stock 14), or lowering the rear from the stock 45-tooth to a 42 or a 43. Going in that direction lowers revs slightly for a given road speed, making the bike a little less "busy-feeling" on the highway. But it would lower effective torque at the same road speed.
Going in the other direction to make the gearing shorter is a bit rarer, though some have done it. This could help the feeling of torque pulling from a stop, but would cause the bike to be running higher revs while cruising. For what it's worth, one of the folks that went to a very tall ratio (15 front / 41 rear), found that gave him the best quarter mile acceleration, so the results aren't immediately intuitive with our bike. To figure out how the revs would actually change depending on gearing, this site is quite helpful to play around with: www.gearingcommander.com
With any of these, if you're only adding a tooth or two, it's unlikely the chain would have to be shortened or lengthened; the stock chain would still work fine.
