Help me understand exactly what ...

Postby Wingsconsin » Wed Jul 03, 2013 1:19 pm



1980 GL1100 Interstate - 85,000 miles
Carb rebuild / cleaning being done and needed.
Filthy - dirty - nasty insides and 1 broken idle mixture adjustment screw.
Results -- New gaskets - and float needles - and idle misture adjustment screws -
Floats set EXACTLY correct after mutiple attempts of the on / off process.
Idle Mixture screws turned out 1-1/4 as per the recommendations
Bench synch per tutorials

Start up -->

IT RUNS !


Here is the question ---
When I did the eventual Vacuum Synch with my 4 guage manomter that has been tested and calibrated I cannot
get the left & right side to balance..The right side is consistently lower on vacuum and they will not match..
1 & 3 match perfectly -- 2 & 4 match perfectly Matching the twins is not possible...??
What am I doing wrong or not doing that I need to look at...?

At the rear of the left carb is the link arm to the throttle.It has a adjustment screw on it.
The screw between the carbs is adjusted first to match vacuum on that side and then the rear screw to balance left to right.

Yes -- when I try that it runs worse and worse and worse...Until it kills completely...
If I leave it ..it runs fine although it has the slight rattle at take off that signifies a need for carb synch...

Seers,

did you test the liners for air leaks?
That could cause your trouble, too.

Good idea...
I could spray a little around the downtubes and see if the idle changes to find a leak...
Always someting with these bikes.... :roll:

Have you done a mechanical sync first with a piece of wire to insure that all four butterfly valves are set close to the same clearance?

Yes -- I did that...
It runs better now..I made some very slight adjustments to the idle mixture screws (another 1/4 turn out) and it seems to have helped...
When it is cold (just started) it still runs kinda rough...but once it is warmed up...Excellent...!
Are the GL1100's naturally cold blooded..?
On the choke it runs fine...but until it is good & warm...off the choke -- not too good...

ignition in good shape?
I've got new wires, ends, and a replayed MSD coil.

No choke required.
