Honda has traditionally designed their bikes to just make redline in top gear going down hill with a tail wind.
In general, you are not going to improve on the factory design in terms of mpg.
However, if you have a specific goal in mind, changing the gearing is useful. I have a 2009 CRF230 that had it's rear sprocket changed fro 39 to 48 teeth. It climbs steep stuff now!
Recommending drafting trucks to riders with unknown experience is dangerous. Even with experienced riders, a minor day dream as the truck starts braking may make it difficult to avoid the back end. I consider that advice extremely dangerous.
