Missing on #2 or #4 Cylinder 1983 GL1100

Postby FlashBack » Mon Jul 01, 2013 7:31 pm



Hi folks. Hope you’re well.
Looking for some suggestions regarding a miss I am experiencing. It is on the left side on either #2 or #4 cylinder.

A little background info to go on:
1) The bike sat for about 5 years
2) Put it right into the shop when I got it and $900.00 later, picked it up running well. Carbs rebuilt, oil, filter change, etc....
3) Put about 1000 miles on it and put it back in the shop for a valve adjustment.
4) Was running good when I first picked it up and within a day started to have the miss on the #2 or # 4 cylinder. I am unable to determine which one.
5) So I changed the plugs with the recommended NGK plug in the owners manual and have them gapped at 0.032
6) It seemed to run a bit better at first but now the miss seems worse and more consistent
7) It occurs at a low idle 1100 rpm’s and appears to be doing this also, although not as significant, while cruising as well.
8) On occasion, when I start the bike, I will get a puff of white smoke out of the exhaust like one of the cylinders is loaded up.

I am thinking:
A) The carbs did not get re adjusted after the valve adjustment
B) The gap is incorrect on the plugs
C) Timing belt jumped a tooth
D) A combination of the above
E) I don’t even want to think that the problem is more significant

I appreciate any feedback, experiences or know how you may have on the issue. Bike is a 1983 GoldWing GL1100 with 23,000 miles.
Happy Trails

A, B, and C will all manifest themselves as problems over the entire rev range.
You've got a plugged idle jet.

Interesting. I just had the carbs rebuilt whgen i put it in the shop shortly after i picked it up. Do the carbs need to come out and torn apart again, or is there something i can do to take care of the issue
Thanks for the response

Are you getting spark on all your cables? Could it be your wires/boots are in need of replacement?
Perhaps it may be your coils? You will need to diagnose your miss and trace it down to your Cylinder to trace it back. Is the miss continuous? Is the cylinder dead? you can test this using a laser thermometer on your pipes. The cooler one is the one missing. trace it back from there.

Thanks for your response. I will do you as you suggested. I know wire & boots arwe new. It does appear to be doing it at higher rpm also, especially if i let off the throttle and keep it in gear, i can hear the miss. I'll post my results of diagnosing.
Suggestion much appreciated

What did the gas tank look like, crud settled in the bottom picked up when res. is tapped thus causing the idle circuit to clog.

Still can't rule this out as well, but I'm leaning toward carb.

2 and 4 share coils with 1 and 3 so mostly likely not coils if not missing on right side too, but could be a loose connection in the circuit on that side?? Probably carb issue..float stuck or set wrong, or dirty jet. Jumped 1 tooth wouldn't cause miss just loss of power bad compression numbers.

Most mechanics have no idea how to set GL floats and they have to be perfect for the bike to run correctly. Dirty gas tank will foul jets easily, how the filter look if it's dirty then stuff is in your carbs floating around. You could drain the bowls and see if there is crap in the bowls???

It appears it is the #4 cylinder with the miss. I have spark plug gap set to .032 on all 4 and looking at the plugs, #4 looks different than the other three. Like carbon/oil remaining on the plug. I will see if i can find it and post a picture.
I did the following on Saturday:
Changed the plugs with proper gap set, changed the fuel filter with the help of this DYI Artcle: http://goldwingdocs.com/forum/viewtopic.php?t=33. Filter cost $2.40.
I also, after determining it was #4, played a bit with adjusting the set screw for #4. I opened it a bit until it appeared the miss was gone. It was very minimal if at all and it ran well on Sunday when my wife and i rode to the coast.
Today, when i rode it to work it appears to have a more consistent miss now.
I'm not new to working on bikes, just new to GoldWings. I'm trying folks. Thanks for all the great advice

Here is an update to my miss on cylinder #4:
Replaced the spark plug cap on the number 4 cylinder with cap model # NGK XD05F. The only problem with using the NGK cap is the NGK lettering on the side not allowing the well cover to completley seal against the plug cap. I'm not to concerned though as i believe any water that might get through would drain through the well hole on the head.
Re checked the gap on all the plugs to 0.032.
This appeared to be the issue. Took it out for a ride. Had to make a couple of adjustments on the fly to the #4 sync adjuster and now running like it was designed to do.
As a matter of fact, i dont think it has run as good as it is now.
I will be replacing all caps and wires in the short term. Any recommendations on wires?
Thanks again for all the advice and suggestions.
It seems I always go to the worse scenerio first when it only took a $3.95 purchase of a plug cap. Go figure :D

This is what I got for mine...Very happy with it/seller. I just got 10' and had enough left in case I messed 1 up.
