I am looking for the Dynojet O2 Optimizers for a 2013 Fat Bob, part numbers are 76423029 and 76423030 and having a bugger of a time tracking them down.

Found them on a US site, $39 for both but postage is $87!!

Can anyone suggest an Aussie supplier who can help me out, my local guy can get them but it will take nearly 2 months!

Superbikesupply.com.au might have them, not trying to be a smart arse but why not get it tuned properly?

I need the O2 optimizers to get it tuned properly. Without them the O2 sensors are still sending input to the ECU, over riding what the Powercommander is trying to do. The Optimizers just send a blank signal to the ECU. Well that's what Steve from Powerhouse told me. Once I have the Optimizers in I'll get Steve to run it over his dyno.

Got it ?? best to stick with what your tuner is good with I guess.

Tell Steve to give me a call......

I have removed the o2 censors completely off my fxst that runs a power commander v
My mechanic had no probs tuning it with the laptop
