Bike went on the dyno yesterday

[Philippe1985]

Just curious, did the dyno operator say anything informative about the A/F dropping out of 14:1 range?

I can understand it richening the mix to some extent but that seems excessive. Did you by chance get a steady state cruise A/F you could post?

For those of you wondering about MPG and why it drops; laying into the gas obliviously kills the FZ mpg!

a quick read:
Air-fuel ratio - Wikipedia, the free encyclopedia

Well they told me that it runs perfect because it stays just under 13:1. The first part was 14:1, but they said that that part of the graph doesn't count. That's all I know. Oh, and they also said that in theory it should have an other value(don't know the number anymore). But that in reality engine's can't cope with that number. That's why it should run under 13:1.

By the way, I ordered akrapovic's today.
