guys,

are new O2 sensor seal rings needed when installing new pipes? Manual says to install new ones, but pipe instructions do not mention this. thoughts? advice?

thanks

 

NO you do not need to replace the orings if the bike is relativly new.&nbsp\\;

 

+1 no need to replace the rings

 

Is there any trick to avoid damaging or stripping the sensor when you replace pipes? I've heard sometimes the threads strip. I'm planning to soak it with WD40 before I try to remove the sensors.
