As some of you know I have a -2 front sprocket on my bike and as such my fuel economy is shocking (around 80-90miles from a full tank) so I'm looking whether Isles worth changing it out.
I'm looking at a 'track day' AFAM sprocket set which is -1 at the front and +1 at the back so it will keep the same level of acceleration.
What I'm wondering is would that be just as bad or would it improve the mpg?

Thanks for that. Some interesting info on there, not quite sure I unsterstand it all haha but it says that my rpms are 13.33 higher than standard in any given gear so does that mean my mpg is 13% worse?

not necessarily - but from my own experience it will be a little less if more revs needed for a given speed (equally gearing up results in slightly better economy for cruising at speeds near peak torque).
