1. If you have a owners manual, plug changes are covered there.
2. Curious, how many miles do you have on the bike? I ask this because plugs are usually good for many more miles than the suggested replacement miles!
Remove the small black inserts from mounting bolts(2) in the chrome strip in the middle of the "valve covers"
Remove the small black inserts from the lower bolts(3) in the spark plug covers.
Remove the bolts(2)(small heads) in the middle chrome strip, lay strip on a towel to prevent scratching.
Remove the bolts(3) in the lower spark plug covers, lay aside on a towel to prevent scratching.
You should now see the plugs. I blow a little air around the plugs at this time to clear any dirt/debris that may be present.
I remove/replace 1 plug at a time, after disconnecting the plug wire, of course.
On the left side, this is a good time to allow the crankcase breather tube to drain(located on the lower front area). Has a plug in the end one removes to allow it to drain.
A dab of anti-seize is suggested by some on each plug. A little dab will do ya'.
Plug gap is 1.0-1.1mm and I use OEM plugs.
Thread spark plug in by hand to prevent cross-threading.
Tighten to 18N-m
Reinstall plug covers and chrome strip
Reinstall black inserts.
