Gear ratio affect mileage

Just picked up my new 12r today. On the way home, I noticed that the mileage went up quicker than I thought. Maybe we were just cruising along faster. At any rate, the guy said he went up one on the rear sprocket and down one on the front.

It would appear the speedo is about 10mph too fast. How does a gear change affect the overall mileage of the bike? Would that make it appear to have more miles than it does?

Also, what did he achieve by going up 1 in the rear and down 1 in the front? Lower top speed with more torque?

Thanks a bunch guys, will post updated pics when I clean this shed/garage /barn find up. Bike is perfect but has been sitting about 3 years and is FILTHY.

10 mph too fast at what speed ? I doubt if that change would make enough of a difference for you to notice while riding. If you want to do the maths have a go at this

If you are traveling 90 on the speedo then you are really only doing 80.

I bought that speed healer i was changing between + 23% from stock to -13% from stock so really needed it... -13% was 17/48, 3% was 19/38 but i had to ride the clutch like a mofo to get going but long days on the highway eating up the miles saves a ton in fuel, for quick acceleration the 17/48 was great might try a 16/48 sometime but not sure
