    one plug doesn't look to be firing as well as the other. The front cylinder looks like it doesn't fire as well. Any ideas, info?

    Maybe a little more info such as any mods past or recent might help. Have you checked for any codes? does it effect the the way it runs/performs? I've noticed on mine the plugs don't seem to burn the same way but the bike runs just fine.

    Like Jeff said, what are the symptoms that make you think this?

    What has been done to the engine (Stage 1, cams, other mods)?

    Give us as much info on the situation so we can try to help.

    Cheers,

    TQ

    Picts would be nice...

    My bike 09 103 King. Shows more Heat at the rear plug as it should, so different color on the plug.

    The Pictures of Both Front and Rear plugs, :newsmile07:will get you more answers...:D

    Totally agree, every Harley I have had has been that way due to the fact the front cylinder catches more air.
