Would you recommend I pull apart all of the wire connectors on the fuel injection sensors on my old 2001 ultra , to clean and add some electric grease? However it is running great and I'm afraid to touch it. I ride in the rain and I'm concerned about corrosion. Thanks

 

consider leaving it alone since some plastics get less pliable over time and can break.

 

If it ain't broke, don't touch it.

 

If there is a time of the year you do not ride much (winter?) that would be the time to be proactive, if you do this I would recommend getting a new housing or be prepared to get one (be sure one is still available) if things go sideways.
