Hi

need some help folks, apologies for my ignorance on this

I am trying to fit some new V&H Big shots staggered to my 2015 wide glide.
The front 02 sensor, is not locating properly in the pipe, and i suspect the sensor thread is beaten up from when the dealer fitted the previous exhaust.

Do i need just to replace with a stock HD 02 sensor, or is there a V&H sensor to be used.
Also, what tap size should i run through the new and old exhaust pipes to be safe

Thanks in advance

 

I think they are ''12mm x 1.25''.

 

Try a little bit of anti- seize on the threads but keep it off the sensor
