My new to me K75RT wasn’t running as well as I thought it should and after a bunch of searching the forum, I decided to do a full tank clean and send my injectors off for service.
The tank was really clean, but I did notice some debris at the bottom. Pulled everything and rinsed the tank, just waiting for it to dry.
Next I decided to pull the injectors, though I had a ton of crud on top of the head by the injector ports, kinda sludgy, so I took my time with paper towels, q tips and compressed air. It was kinda funky. Upon pulling my injectors, I noticed the #3 injector has oxidation on it. I’m assuming DeOxit should take care of it, but I’m trying to figure out why there would be oxidation.
Should I replace the rubber grommet in the plug?
