running on two cylnders

Postby awsimpsonjr » Tue Jan 08, 2013 1:02 pm



i have electronic ignition and two coil packs. the front coil pack didnt seem to do anything, i used the back ones to hook to the front and still nothing, although both coil packs will run the rear cylinders. this is unusual and im not sure where to go from here. it is a Honda Goldwing GL1000. i figure something isnt telling the coil pack to do what its supposed to when hooked to the front. any information on how this works or possible ways to fix this issue. thanks in advance. ALSO i have an issue that mayy be related. with everything hooked up and the front cylnders not really working and im riding , i feel like i have a lack of power and then it kicks back in. i dont feel as if its timed problem, its intermittent but im lost and dont have a clue what to do.

Can we assume the ignition system is a aftermarket add on?
The gl1000 had points.
If yes,you may be able to contact the manufacture for support if you can get a number from the module.It may be a Dyna system.

My best suggestion.Go to this site...http://www.dynaonline.com/skins/downloads/Default.aspx

Look for this...DYNA S DS1-3 for Honda GL1000 Motorcycles DS1-3.pdf

Download the file for testing info.
You either have a bad unit or wiring to/from it.

Do you have fresh spark plugs?
It could be plug wires and or spark plug caps too.
Or plugged fuel ports? Has it been sitting?

New plugs.replaced coils and wire set with used set said to be good.and I ride every day till last week..I am not a mechanic and can't find anyone to work on in tampa bay area.I would buy new coil if I knew where.am researching the dyna ignition.endcaps I will swap front to back and see what happens..ty

If the ambient air is cold and wet, above 30%, the plug wires and caps are highly suspect. You can buy new wire in bulk, 7mm(7') and new NGK spark plug caps at most small shops, should be @$30-$40 tops.. Call around to see who stocks them and prices. It's not a hard job. They screw together. There are metal tangs you'll need to reuse on the coil end and rubber seals /farrels for the coil ends.
Used plug wire get leaky and causes the missing while motor is cold and moist especially this time of year with cool mornings.

I hope you used NGK plugs. Hondas work best on the stock listed NGK plugs.
I have seen many bikes in the 70's that came into the shop with other plugs installed that wouldn't run for beans until new NGK plugs were put back in. It's still the same today.

Look close at the coils, there should be caps that hold the plug wires to the coils. Maybe Honda didn't start doing that until the 1100 coils.

You can replace them with Dodge neon coils for better spark.

On the 76 gl1000 it is all one part .I have been told that the 1100 coil would work but I don't have extra cash to buy another set if not sure they would work

Yeah, on the 1000 the wires are made onto the coils- about the end-caps: there are little resistors- that look kinda like mini fuses in them. I replaced the resistors on mine with little pieces of brass rod. They come out the spark-plug end of the cap, look in there and you'll see where there's a screwdriver slot on a brass piece that unscrews, then there's the resistor- and a SPRING! -At least check them for the correct resistance (I think it's about 5k, but you'd better look it up.)

Sounds more like a points problem than anything- but since you don't have any...

Does it still have a condensor? -Might check connections from your unit #1 & #2 to the coil for continuity. I've had the same problem- a few times- but like I say, mine still has points.

Sounds like you're on the right track. Happy hunting and let us know what you find out. 8-)

What do you mean when you say running hot, where were you on the gauge? The fan comes on pretty low in terms of the coolant temperature so the fan running does not tell me it was hot. If the gauge was well into the red, then that is different.

Gauge inop? Even with the fan running got hot enough to boil over... hmm. Might want to make sure the thermostat is opening as it should- and that the radiator is flowing right- but I wonder first if the radiator cap itself is holding pressure(?) -Just a regular automotive cooling system checker/ cap adapter will check it

Yes, the system must hold pressure so the cap, then a system pressure test are the first things I would check.

Temp gauge works and goes up when at stop lights.got caught at drawbridge and temp gauge kept going up. I got nervous when I noticed coolant coming out and hit kill switch fan kept running.when I started temp was lower and I came on home without any long stops .when I shut off could hear bubbling.father in law old school auto mechanic..said just take out thermostat bike didn't need it.is this wise?

:shock: That's not sound advice for an automobile, let alone a Goldwing! -I hate to be so blunt about it, but that's been my experience. I too used to work as an automotive mechanic for nearly 30 years, at one time had 7 A.S.E. certifications under my belt (for what that's worth). :o

Besides the reasons for the thermostat (and thus the temperature the engine was designed to operate at), which would take some explaining- for now lets just go on blind faith that it was designed to have one, and the temperature regulated to what it is (is) a lot of components working together to provide a long distance, high performance, precision engine- durable, powerful, etc... :D

Trust me, it's there for a reason. :roll:

I don't want to get into a lot of controversy about replacing it with a 'non-mother-Honda' component- but I did put one in mine from O'Reilly's that opens a little wider, blah, blah... (we'll see. I only changed it because I was doing a water pump as well, and I guess force of habit... even though the old one checked out - it's just SO OLD for a thermostat- .) Put it in a pan of water and it should be open before the water boils- better yet, use a thermometer.

Something I've seen way too much of - especially here in Texas- is what happens when people "just take it out". The system is designed to have certain flow dynamics and there is a place where with the thermostat fully open that is the maximum amount of coolant that is supposed to go through there. In other words, if the coolant goes through the radiator too fast it's not in there long enough for the heat to come out through the fins- and it just keeps getting hotter and hotter...

I just got home from dialysis and don't seem to be doing very well with this- in short, the thermostat is important (think about the one on your house? Your stove/oven?) Take it out and check it, either replace it or put it back in there! Flush out your radiator - make sure it's flowing real good. Make sure your timing is not too advanced, and that you're not running too lean from vacuum leaks, plugged up carbs, etc. -and like we said about the cooling system holding pressure-

I'm signing off now- 8-)

Ty so very much as l am not a mechanic. I have read the book on replacement of thermostat and will replace if not working properly.may God bless you and your family.

8-) Hey man, any time - if you run into something you can't figure out don't hesitate to ask- better to understand and take your time than risk tearing something up. You can download the entire Honda Service Manual on here. Use it (I sure do!)

God bless you and yours too, and thanks :)

(And don't forget to check out the radiator cap too. Those go out probably more often than thermostats ;) )
