So I'm thinking about changing the exhaust on my Gen3.
The service manual indicates it should be an easy job - here are the steps:
1. Remove lower fairings (done that multiple times during oil changes, trivial)
2. Disconnect and remove the O2 sensor
3. Remove right frame cover
4. Remove right footpeg
5. Remove exhaust pipe holder nuts
6. Remove the muffler
And then installation is described as the reverse, but with the added step of replacing exhaust pipe gaskets. I've already sourced 2 such OEM gaskets.
After a more careful read of the service manual, and gathering info from some other chapters, I found out that:
- When re-installing the O2 sensor, you need to apply silicon grease. This is confusing to me, I thought it'd be copper grease, as this part is subject to a lot of heat, and (dielectric) silicon grease should instead be applied to the connector, not the threads of the O2 sensor itself?
- The O2 sensor looks like it has a washer underneath. Copper, I think? Should I replace it as well? Neither the service manual, nor the parts list seem to indicate it's there, am I seeing things?
- The O2 sensor needs to be torqued according to spec. I have a torque wrench, but since there's a cable sticking out of it, my regular sockets won't work. There are special O2 sensor sockets, like the one I attached, with a long cutout for the cable. Should I get one of these?
- Anything else I'm missing? I'm sure some people skip such details, but I'd like to learn how to do things properly
