Poor running question

Hey Y'all

I have a 2006 Monster with 29,700 miles on it.  I removed the tank for my
normal winter storage so it will sit empty and shrink back to its normal
shape. At that time I removed the battery and air box and checked the
valves and only adjusted one.  When I put it back on the road it did not
run correctly.  Part and especially steady throttle have a lot of surging.
Moderate to full throttle seems to work pretty well.  A friend suggested
having the fuel injectors cleaned.  I have run enough car and fuel
injector cleaner through the motor it should be nice and clean.  I rode it
Monday and it is actually a little better but still not right.

Yesterday I put it on the lift and started stripping it down.  Well as I
removed the air box I noticed the coil mounted to the let rear had one of
the plug wires disconnected.  That would be my fault because I did the
valves a while back I had to unplug them to remove the air box.  It has
not been running right since.  Now it is a dual spark head and the other
plug wire was fully seated.  Could only having one spark plug working cause
my symptoms?  I am on the horns of a dilemma.  I can put it all back
together and go for a ride and if it works I am done.  If not then I have
to spend all that time taking it apart again to remove the fuel injectors.
Any thoughts?

Oh man if it ain’t broke don’t fix it :P Store the bike in a garage and
leave it alone next time :)
send the tank to a shop so they can caswell coat it..

You wouldn’t ride it if only 1 spark plug is working. Unless it’s a
thumper!

It was something I really needed to check.  The valves had about 20K miles
since the last check.  The gas tank removal has nothing to do with the
coils so I never experienced this before.  I think I may just button it
back up.  A lot of work but hey it is a fun bike.

As far as one spark plug it is a dual spark so one of two was still
firing.  I am guessing that the lack of one was a problem at low flow
velocity and higher rpm and more wide open throttle let thing swirl and mix
better.  We will see.

Are the spark plugs configured as parallel or series?

Sometimes the sparks travel from one to the other like a loop. If one isn’t
firing, then you’ll get a misfire. If the other one isn’t firing, you’ll
have an inefficient combustion.
Dual Spark Plug Theory is to create “flames” inside the chamber for a
complete (“Burn”) combustion with less piston travel.

I’m with Jack. My gut tells me that missing the one plug  could be the culprit. One question-does the disconnected wire disable one plug in one cylinder, or one plug in both cylinders?

It is one coil with two outlets so I assume they are in parallel.  The bike
started fairly easily although I did have to open the throttle some to make
it "catch".  I have decided to put it back together and make sure I put
that last plug wire back on.  I suspect because there is a bolt under that
wire that holds the coil to the air box I pulled it off to release the
coils and then never put it back on.  It was not loose it was fully
disconnected.  I will report my findings when I get it done, hopefully
today.

Are the spark plugs configured as parallel or series?

Sometimes the sparks travel from one to the other like a loop. If one
isn’t firing, then you’ll get a misfire. If the other one isn’t firing,
you’ll have an inefficient combustion.
Dual Spark Plug Theory is to create “flames” inside the chamber for a
complete (“Burn”) combustion with less piston travel.

Hey Y'all

I have a 2006 Monster with 29,700 miles on it.  I removed the tank for
my normal winter storage so it will sit empty and shrink back to its normal
shape. At that time I removed the battery and air box and checked the
valves and only adjusted one.  When I put it back on the road it did not
run correctly.  Part and especially steady throttle have a lot of surging.
Moderate to full throttle seems to work pretty well.  A friend suggested
having the fuel injectors cleaned.  I have run enough car and fuel
injector cleaner through the motor it should be nice and clean.  I rode it
Monday and it is actually a little better but still not right.

Yesterday I put it on the lift and started stripping it down.  Well as I
removed the air box I noticed the coil mounted to the let rear had one of
the plug wires disconnected.  That would be my fault because I did the
valves a while back I had to unplug them to remove the air box.  It has
not been running right since.  Now it is a dual spark head and the other
plug wire was fully seated.  Could only having one spark plug working cause

I do not see how they could be in series.  My logic for saying parallel is
that in series if one we totally disconnected like mine was then both would
not work and my bike would have been running on one cylinder.  It was
clearly running on both cylinders just poorly at low rpm and part
throttle.  It was miserable in intown traffic but was almost normal out on
the open highway.  Not saying you are wrong because I really do not know
but just sharing my logic.  Christmas tree lights that are in series have
the whole string go out when one bulb burns out or is removed.
