I'm using a FAST A/F meter on my Rotax bike...

Works great and has allowed me to fine tune the jetting without a dyno. When not in use, I simply plug the bung in the exhaust in order to preserve the O2 sensor. The unit has a playback feature which is useful so that you're not trying to read the thing at WOT in third gear! They are a bit pricey though, but I have a few projects in which to use it on, so the cost was justified. I think sharing it amongst a couple guys to offset the cost would be a good idea.
