Harix,
I am not sure this is a US bike but it sounds like it since you had to
remove the brass plugs. Unfortunately, outrageously different settings
on the pilot mixture screws from the factory aren't that uncommon. It
almost makes you wish that this was a mistake rather than a reflection
of the equality of the carburetors. I would like to think however that
"this" was actually adjusted from the factory since the caps were
installed. For all I know .. the caps were installed at the dealership
by some "angry beaver" who is supposed to tune the bike as part of the
assembly process ... I really haven't a clue.
Anyhow .. .IMHO .. I think I would be looking for about a 3.5% CO
reading, (A/F 13.18 or so). No more than 4%, (A/F 13.00). The part I
am missing here or don't understand is "why" you can't get below 7+%
.. I suppose if you open the throttle plates sufficiently you could
pull something out of the jet needle but I doubt it ... you most
certainly could be pulling from one of the bypass holes if you were
wildly out of sync ....... I just don't get it ... if you are trying
to idle a 1K and close all the screws the bike should die .. closing
the screws almost completely should have a significant impact on your
readings, (even if you have to adjust the idle up to keep running).
Are you saying this isn't happening ?? Are you reading from the pipe
plugs for each cylinder or from the tailpipes ?? You can also try
pulling the crankcase vent out of the bottom of the airbox and see if
this impacts your readings and of course I assume your machine is in
good calibration, (no offense .. sometimes it is hard to get a reading
on a bike). Also try putting a blast of compressed air in the large
jet at the top of each carb, (this is the primary pilot air jet), and
they see if you impact the readings .. if so then you are plugged up
and have opened the throttle enough to run off of mixture escaping
from the pilot bypass holes which would of course fairly well ignore
you and your screwdriver down at the mixture screw ......... just a
thought ......
Sorry for all the questions . ... just confused .... Wow ... neat job
.. do you guys have a roll on dyno too ??
