what size was the sensor? Also what year is your bike. Might be wrong but I thought the newer bikes were smaller. I'm going to have to pull mine on my 07 ultra. Just wondering if anyone knew what size it was

Isn't that the thread size?

I find it much easier to unhook the connectors, and then use an open wrench on the sensors when the exhaust is taken off the bike. The connectors are very easy to access front and rear.

I use the open end of a combination wrench to swap out the O2 sensors. I think it's either a 7/8'' or 22mm wrench. I can get to both sensors with the exhaust still mounted on the bike. Works for both the OE sensors and the Wide Band sensors I use for AutoTune.
