Topic: Anyone used K&N Air/Fuel Ratio Monitor?

[ampsrampstramps]

I'm about to add a K&N 85-2441 Round Air/Fuel Ratio to my cart but I would like to know that it is going to work before I do so. http://www.knfilters.com/search/product.aspx?Prod=85-2441
It doesn't say anything about motorcycles on the K&N page but I swear I've read somewhere that you can use this on a bike.
How does it install and does it have to be permanent?
If you guys have a better solution let me know. I'd prefer something that I can put in temporarily, run tests, make changes and then take it out.

I just did a quick search for "motorcycle air fuel monitors" and found a lot of options. I'd still like to know what you guys think.

You can see links to my bikes below to know what I'll be using it on.

I would buy something with a data logging.

There are much better units out there. http://www.fastbygast.com/wego%20page.htm

Thanks guys. Good to know.
Do you guys leave them in permanently?

I have one of the K&N units on my turbocharged Z1.  I bought it 5-6 years ago when the choices were limited.  It helped a ton to diagnose a carburation lean spot, but having to look down at the readout isn't ideal...  in fact it's downright scary...

I will be upgrading to one of these AEM gauges - they are wide-band and have data logging - and have a dual readout with boost AND air/fuel.

I will probably permanently mount this gauge to my bike, but I have a bung plug that would allow me to remove the sensor and plug the hole.

Perfect! Thanks. Great idea on plugging the hole.

The bung-plug should be carefully measured to form a smooth and level inside surface for best exhaust flow. Do not use leaded fuel if you leave the sensor in place.
