I put on a set of
Nemesis coils about 100 miles ago and today I put in my
Dyna 3000.
As a baseline, I thought I would check out the plugs before running the bike. Since putting on the coils and hi-perf wires I have not noticed a difference in the bike. However, upon checking the plugs I have notice a small difference in the way they look. Unfortunately, I can't find my pre-coil pics.
Front plug:
- electrode - fairly clean before and after coils
- porcelain - fairly clean near tip before and after, slight coloration moving down to the base
- ground strap - cleaner after coils and you can definitely see the timing marks
- threaded body - black before coils; after coils, the top of the threaded body seems to be 'cleaning' itself (for the lack of a better description) as evident by the silver blotches
Rear plug (poor pic):
- electrode - black before; brown after
- porcelain - black before; slightly whiter at the extreme tip progressing to black
- ground strap - black before; white at the tip
- threaded body - black before; black after but odd silver speckling
It's unfortunate that I did not have more miles on the bike before putting the Dyna in. Overall, the plugs seems to have less carbon deposits on them than before I installed the coils and I would be interested in seeing if the plugs would even be 'cleaner' after another 200 m.
I'm going to pull the plugs after another tankful (probably in a month the way it's going now

and see what's up.
