What do you think of these spark plugs?

1100es. K&N pods, Yosh street pipe, Dyna 2k ignition, stock motor with 1150 cams, Stage 3 kit with dyna 132 mains, 4th clip.

Had it dyno'd last year and was running rich with the 138's so went down to the 132's. bike runs well through the range with no hesitations.



Looking at the threads on the plugs, it looks like i'm running a bit hot. Thinking of dropping the needles down to the 5th clip.

What say you.

They look dang near perfect. A nice tan on the insulator, and no white on the electrodes.

Are you concerned about the slight blueing on plug #2?

[niclpnut]

Yeah. My understanding is if I'm seeing more coloring up the threads than 2-3 threads its an indication that its a bit lean. Additionally the middle part of the porcelain is a bit light.

I like what I see...... about as spot on as anyone could really ask for. The engines in no danger as they are now would be my opinion.

Very nice looking, good info also. My 1100 is going to have the same parts so i can try those settings to begin.

Thanks for the info!
