1978 GL1000 NEED HELP ... Thinking about selling.

Postby swr1977 » Fri May 22, 2015 6:26 pm



My 78 GL1000 let me down last summer. Started out on a ride and 1 mile from home all the sudden I had no power when accelerating and started making a rattling noise but don't know from where. Parked her for the rest of the summer and then did did my normal winterizing , a oil change with new plugs, drained gas from carbs and disco'ed battery. When I tried to start her up last week, no start, just same rattling noise.

I want to keep her going but just spent way to much to get my car back on the road. So I'm wondering if someone can help me out? Anyone in the Everett Washington area that has some time I would be willing to pay for lunch/dinner if you have the time to come look.

Also thinking of selling but don't know what to ask for a non-starting bike. Please look at pics and someone give me there opinion...

Pictures from previous post were taken last summer. Below are current pics... I have not put the chrome engine cover plates, rear foot pegs and front fairing covers back on the bike since last years winterization. Also the lower bumper is currently removed because I was swapping out bulbs for LEDs.

As seen in pic there is currently 87062 miles on her.

Got her started yesturday. Same rattling sound. Can't tell where it's coming from. With bike on center stand I put her in gear and sound goes away when I let out the clutch.

I will make a video and post asap.

Any help/suggestions would be greatly appreciated.

That sure sounds like valve noise - and just before you shut it down, I thought I heard what could be compression coming back up through a carb. That could indicate either a stuck valve, or broken timing belt. When you have it running, are all four exhaust runners (pipes coming out the bottom of the cylinders) the same temperature? Or are some hot and some cold?

I haven't run the bike long enough for it to get very hot. The last 2 weeks since I first started the bike this season it has maybe run 15-20 min. Exhaust coming from both pipes about same temp.

It won't take long - maybe ten seconds, you'll know right away which ones are getting warm and which ones aren't.

Ok finally got my uncle's help. We think one of the coils is out being #3 & # 4 manifold pipes are not getting hot.

Are there any "how to" topics coving how to test/ change them? I looked/searched but didn't find any. I have dyna coils & a Dyna III electronic ignition.

Also where is a good place to find a replacement?

How old is your Dyna stuff? Coils don't often fail. Is there a loose wire? You can check for spark w/ an old plug, grounded. Turn off the gas. If you pull a plug to check for spark, don't catch yourself on fire. If it's the module, they have excellent customer service. You can check the coil by switching the wires all around.

Sorry about slow reply to your post/help ...

I just haven't had the time to work on this project the past week or so. I haven't seen any loose wires. I've had plug #4 out and it has no spark ! I'll check #3 tomorrow.

I found this link on YouTube showing how to test coils...



Is this also the correct way to test Dyna coils?

Also ... Can anyone tell me if it's OK to start my bike with the front fairing off? I'll be having to disco the wires to the headlight, turn signals and radio in order to get to the coils out/remove them if I have to replace them.

My vetter has a 9 pin plug on the left side (plus a separate plug for the radio). You can run it w/o the fairing. I would think the testing of coils would be fairly universal. The more likely culprit would be the wiring or timing module.

I was looking at the fairing last night. I have the 9 pin plug on the left side and also some other wires on the right side for a few switches that unfortunately the PO didn't make/install a quick release plug for. :cry: Bummer for me! With any luck I wont have to remove the fairing.

You asked about the "Dyna Stuff" ... the PO ungraded the original points and ignition so I'm not sure how old it is. I'll be working on it today so I'll let you know what I find.

I'm still thinking about selling the old gal. Any idea on what she's worth $$$ if I don't get her running? And even if I do I'd like to know what her value is running also? Please take a look at the pics in the first few posts and tell me what you think.

Thanks for the info and help!

Probably the best way to figure a price would be to keep an eye on CraigsList for your area. I added the radio (had the housing from PO and made sure ir plugged in. Radio shak has plugs you can wire up.

After removing and testing the coils and wires ... I have 2 bad wires and a bad coil.

Found a set on ebay for $135 http://r.ebay.com/1WzJuD

I've ordered them and hope to have them on by next week.

I'll let you know how it goes.

The new coils are mounted in the old bracket and they are ready to be reinstalled but I'm not sure how to make up the new spark plug wires. Can anyone help with this or link me to a forum with instructions?

This is what I have (Yellow is old ... Black is new) Old cables have no continuity! I'm hoping I can reuse the plug jack caps but when I test them I don't get any continuity!

I'm assuming I'll have to cut the new cables and crimp new ends on them but I don't know how nor do I have any special crimping tools.

There's no crimping. At the plug end, feed the cut wire through the soft rubber parts, then push it into the plug boot, the spike you see will go into the center of the wire. The coil end works the same way. The boots are available from NAPA http://www.napaonline.com/Catalog/Catal ... 0488834594

If no crimping of the wires is needed then why did they send me the bag of connectors and boots? The coils do NOT look like or have a screw thread like the boot cap for the wire!

Is there a way to test my spark plug boot cap connectors? Two of them were working when I disassembled but now I don't get any connectivity when testing with a DMM. Am I don't something wrong or are they bad?

My bad. I don't have Dyna coils, so this is above my pay grade. Hopefully, someone will be along shortly to help with that. Here's a quote from another thread about the boots -- by HawkeyeGL1200 » Sat Mar 07, 2015 7:27 pm
Have you checked the resistors inside the plugs boots to make sure they're tight inside the boot? One of the things I have taken to doing when I change plugs is checking the resistors out to make sure they're clean and tight in the plug boots. You may have some corrosion or a loose resistor that allows that cylinder to miss at idle and then as RPM increases, and voltage stabilizes, the miss can disappear.

Read more: viewtopic.php?t=25999#ixzz3fKP7ftFj

If the resistors are good, there is not a whole lot else in there. I check mine w/ a spare grounded plug (in the shade) and see if there is spark. The ones that were on my bike were so old, they disintegrated when I messed with them. For $16, after what else you've spent, I'd bite the bullet. As an after thought, when you look in the hole on the coil where the plug wire goes, do you see a spike? If so, follow earlier instructions. Those pieces look like they would go on the plug end for other applications.

Thanks for the Napa Link, part # and $$$ cost... I live in a small town but that is the one auto parts store we have here in town. I'll be calling them in the morning to see if they have any in stock. If they so then all I need to to if figure out how to cut and crimp the new wires to the correct length, re-assemble and I'll be riding again! (crossed fingers)

Napa didn't have the sparkplug boot cover/caps in stock... I did find (Honda Dealership) that did and I figured out how to make up the cables with the help of the parts person at Everett Powersports Inc.

What I needed to know that he showed me in addition to cutting/crimping the connector onto the end of the wire was that the spark-plug boot has a resistor in it that is 5K! after I found that out and got home, I tested the old set... they all work fine but being I had just purchased new I of course used the new ones.

I finished putting together the spark-plug wires this-morning and also have new coils installed ... took her for a ride today and other then a turn signal bulb out somewhere on my right side she's up and running!

Black Beauty is up and running again!

Good deal. If the bulb is in the fairing, they come out from inside the fairing. Enjoy the ride!

As it turns out... I had a loose wire under the seat causing the blinkers to run slow. Time to go out and buy some good connectors/plugs to rewire.

WingAdmin ... What do you hear now?





Anyone else / All others please feel free to chime in and tell me what you think... I want this bike running right. She sure seems to. Went for a ride yesterday and she has all the power I remember and more. Amazing what new coils, wires, plugs and plug boot caps will do!

Oh and Also she is still for sale... Anyone interested let me know via PM

I'm no good at listening to someone else's bike for problems, sounds great to me. Fits perfect on your porch, looks good there. I would not sell. :mrgreen:
