Title: Question about O2 sensor
Post by: exfed12825 on December 04, 2011, 05:08:47 PM
I have a set of true duals in the barn witout the O2 bung, can I use them on my 07 Road glide?

Shure just weld bungs on them and get em tuned.. Or get em tuned without the bungs... Max

you may have issues with the 6sp side trans cover sticking out too far if the pipes were for an '06 and older.  :nix:

Good point.. Might have to re-fab that bracket.. Also if there is a mount for the rear cylinder head pipe. It might need change..Starter bracket may be different.  Still it's a skinny tire frame on the 07.. Newer 09 up frames have an offset in the pipes.

just a thought but did not the 07's have unheated 02 sensors so they probably need to be up closer to the ports anyway.

The sensors are very close to the head, can they be programed out, and if so what will I need ?

you will need to have the bike tuned to run open loop, which means you will need tuning software and a good dyno tuner.  If you decide to run those pipes, you will need to tune the bike even if the o2 sensors are retained.  The difference is you can do a decent tune yourself with the right tuning software if you install the o2 sensors (in the right location, of course).

I think I'm going to have to pass on changing the pipes for now and then I'll buy some new ones built for this model and a SE cone air cleaner, that way I can have it tuned one time.

If the pipes are Rinehart true duals the early pipes will not clear the primary on the rear cylinder.
