Still working on getting the basic maintenance done.
Time to change the spark plugs.
Relatively simple task.
Remove the engine cover and the windshield cowl.
Then remove one of the coil packs.
Next, a 5/8" spark plug socket and a good ratchet in needed
Recommend applying a little PB blaster into the spark plug hole first.
Turn the ratchet ~ 1/8th of a turn, then go back a 1/16th of a turn.
The forward and backward movement along with the PB Blaster helps to prevent the spark plug from seizing up in the head. Continue the forward and backward movement until the plug can turn freely.
The old plugs were original to the BMW.
Replaced the plugs with NGKs.
Used some anti-seize which should make the next plug change easier.
Put everything back together.
The N51 runs very smooth.
