How much would a 1 down 3 up sprocket swap effect the mileage on my bike.

It was put on at 300 miles and the bike has 14k on it now.
Im trying to get the actuall odometer mileage.

2002 hayabusa
stock 17 front 40 rear
now 16 front 43 rear

3....

.... Yes, 3 is the answer.

Im a friggin idiot. The faster you are traveling, the further the speedo is off

faster your going the more miles it will be tripping. Theres no way to get the exact number
:dontknow:

a stock busa will NOT pull 230

Ya ya, they fall off in 6th, but gas milage.........and maybe not stock

178 hp stock... with the headers and exhaust, intake, cam, and dyno tune it must be near 200-205 modest
