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?
