Oil Change Reset
A press of the OIL CHANGE RESET switch will allow you to
reset the oil life feature to 100% (or your Personalized Oil Reset
Percentage). After you have the oil changed, you must execute
the following procedure. Press the OIL CHANGE RESET switch
and hold for five seconds as the M/C counts down for five
seconds. After a successful reset the Message Center will display
“OIL LIFE RESET TO 100%.” If you have established a
Personalized Oil Reset Percentage, the display will show that
percentage instead of 100%. To ensure accurate oil life
indicators, perform this reset procedure only after an oil change.
Your Personalized Oil Reset Percentage allows you to establish a
smaller oil change interval than the manufacturer’s
recommended interval. To establish your Personalized Oil Reset
Percentage perform the following procedure:
1. Press and hold the OIL CHANGE RESET switch and press
the RESET switch while the display is still counting down
the 5 seconds to reset. The display will change to “START
OIL LIFE AT XXX%.”
2. Press the OIL CHANGE RESET switch until the displayed
percentage is the Personalized Oil Reset Percentage that you
desire. Your choices are 100%, 90%, 80%, 70%, 60%, 50%,
40% and 30%.

You will have to pull the engine and remove the crank shaft and connecting rods you have a bad rod bearing. I will strongly suggest taking to a machine shop and having the crankshaft turned and the rods resized. This will be no minor undertaking and will require time to repair. You could also look into purchasing a rebuilt engine.
