    We are in the process of rebuilding a 250 Ninja and I want to be able to monitor the AFR at all times. Is this possible? Is there a fairly inexpensive way to do this for say <$100? Any help is appreciated...

    I wanted to be able to do this also.

    You'll need an oxygen sensor mounted in the exhaust, which only some bikes have stock. You can add an o2 bung and wire one up. There's lots of options for AFR gauges. I think the o2 sensor would need to be a wide-band from what I remember.

    If you are just curious about where you are at, you can probably just do a dyno run and have them print out your A/F curve.

    +1 on the wideband idea.
