You'd really want to check the color of your plugs while you are
running at speed but that's a bit hard. One way to do this without
endangering your life is to:
- run your bike at 3/4 throttle to WFO for about 2 miles. This gets
the bike to use mostly the main jet.
- find a place where you can pull to the side of the road and turn the
bike off BEFORE releasing the throttle. This will make sure that your
plugs haven't been 'influenced' by any other fuel circuit.
- pull the plugs on the side of the road and have a look-see.
I did this on my Eldo and found that one side was tanish (intake) and
one side blackish (exhaust). I have stock jets, needle and needle setting.
What I find unusual about your plugs' color, Dennis, is that you
checked the plugs after arriving home which means that they should be
more on the Dark Side because of the lower speeds.
If memory serves me well, raising the needle does wonders for
transitions between the pilot (idle) jet and the main jet but at 3/4 to
WFO it makes no difference. I'd check your main jet to see if it is
clogged or not stock.

I have a concern over a plug reading I took after the
Maryland Rally. Most of my riding time on my Eldo is spent riding
country roads at a brisk but leisurely pace, on and off the throttle
thru turns, slowing thru small towns, etc. Kind of like our loop loop
at the Md Rally. The only sensible way from my house to the Maryland
Rally, however, is highway riding. I spent the larger part of my ride
to and from the Maryland Rally consistently at 65-80mph. I did a plug
check the following day after arriving home, and found the plugs to be
more white than is healthy. Usually, I find them a more tan to
chocolate color.
Here's the question(s):
1. Should I be concerned about this condition, since I
don't spend the major portion of my riding time at these consistent speeds?
2. If I wanted to make an adjustment, would it be to
the needle, or main, what?
Thanks,
