Despite not wanting another project after selling my 500 four I ended up buying a pair of goldwings and extra spares as a job lot. One is complete but tatty, the other is in many pieces. not sure what the plan is, but first I am trying to get the blue one going to assess what I have then decide if to sell one to fund the other. Any other Goldwing owners on here? They do only have one cam per side! I have started by removing the carbs to clean them, don't look too bad in the one I have opened.

Thats true, it is indeed a SOHC four. ;D

Hi Mick,
Another Wing man here. I've had 6 of them (so far).not to everyone's taste I know and I've had the usual comments of 'Why don't you just buy a bloody car?'
I still have a very early GL 1000 and an anniversary GL 1500
Lots of stuff still available for your GL and they are starting to be worth good money as are most 70's bikes. I've often pondered the fact that they have one cam per bank and four pots (except the 15's and 18's anyway) but have never wanted to rock the boat on this forum. Carbs can be a real pain to get right with all the small passages. Worth looking at Randakk's site, he's the US guru and has a video available for carb build and can supply awkward stuff.
Also have a peek at Steve Saunders site, lots of good info there.
Keep us all informed of progress.

thanks Ian I always wanted a wing back in the day, I prefer the look of the early ones best. one of the things I got with the bikes was a carb rebuild kit from randakks complete with dvd, a very comprehensive kit.Is there a uk forum for them?
-
Hi Mick
I haven't come across a specific UK Wing forum - but that doesn't mean there isn't one. The Steve Saunders one is my favourite and there are stacks of UK members on there. Glad you have the Randakk's DVD and kit, that will help a great deal. If any head gasket work is needed, they don't seem to like spurious ones, only oem seems to do the job.
The Wing is a very capable bike and I have done over 100,000 miles on them. I would not hesitate to set out on a 1000 mile trip on my 1500 - except today perhaps, we have storm force winds here in Orkney and all ferries cancelled :(

very slow progress on the bike, the carbs are very complicated and time is short for me at the moment. I have bought an ultrasonic cleaner to clean them, any tips on using it?

Get some ultrasonic cleaning fluid specifically for alloy from Allendale Electronics on eBay

well some progress made, carbs cleaned and rebuilt, timing belts renewed and radiator removed for better access. New battery now fitted, but electrics have been tampered with so a bit of work needed, I have the engine turning over and a spark, will change oil etc before attempting to start the beast. meanwhile I have been looking at the brakes, calipers have been cleaned and rebuilt with new pistons and seals, master cylinder needs full overhaul so plenty still to do.
-
Its worth getting the rad flow tested as they can sludge up in coolant mixed with tap water has been used
-
will do Bryan, when I drained the rad the coolant looked very clean blue colour indicates antifreeze was used so hopeful it will be ok
-
update on progress, have renewed the headstock bearings and rebuilt the front calipers, master cyl is clean and waiting for a rebuild kit to arrive. Electrics are a mess, lots of extra wires and bad bodges so some rewiring to do
-
it lives! finally had a few hours working on the bike, replaced the rad and refilled with coolant, changed the oil and filter etc, (cam belts had already been done). These bikes are a bit tricky to work on, not much room to work around the carb area, but I used a remote petrol tank to make sure I had clean petrol and after a bit of cranking and some carb cleaner down the intake it fired up with a few spits and misfires and a very loud exhaust as it has a home made 4 into 1 system on at the moment. Lots more to do but a happy chappy.
-
Great feeling when they burst into life, good work Mick!
-
Great news being a big old girl you would think there would be plenty of room.
A bit of spit and polish she will be back on the road. ;)

That's great news, it's always good to hear some old bike that hasn't run for years roar into life.

Just working on my mates 1200 trike and all the wings can have a charging problem, you need to check for AC voltage with a multimeter on al three pairs of yellow wires coming from the alternator (3 wires make 3 pairs) all three readings should be the same, the one I'm working on has one pair low voltage even though all three pairs seem to give the same resistance.
The reason they give trouble is that the generator is going flat out all the time and all the regulator does is dump current to earth when the battery voltage is up.
As the engine has to come out to swap the stator is worth checking as soon as you can
-
cheers Bryan will check as the wiring has been butchered in the past
-
lots of work been done and its back in one piece but having some issues with running. for the first few seconds when it starts with choke it sounds ok but soon seems to go off, in fact the two cylinders on the left don't seem to be firing as I can remove both H T leads with no change in the running.( they are on two different coils). things checked are: carbs cleaned and rebuilt, new cambelts renewed and timed correctly, new Honda points plate, gapped and timing spot on, new plugs. I did sync the carbs but difficult with the uneven running. I also checked compression which is similar on all cylinders, also checked and adjusted valve clearance. today took carbs off again and found a sticky piston, but no change in the symptoms. so a bit stuck, I still think its fuel related, I am using a remote tank with clean fuel. Any experts out there?
-
Hi Mick,
I know little about Goldwings except, like others, I always liked the originals. Only just caught up with this thread and laughed out loud when I read you started it and it was loud... not something I've ever associated before with a 'Wing!
Keep at it and good luck with the resto.
Cheers, D.
-
Thanks oddjob yes they are a bit different to the other fours, I cant sync them until I get it running reasonably.
-
If you're sure it's not running on all the cylinders as you've done by taking the HT leads off, then spray some carb cleaner or easy start down the non running carbs and see if it fires them then. This doesn't correct anything but shows if you have ignition and helps separate your further work into either carbs or sparks and gets you going in the right direction.
Alternatively get a long thin clear plastic pipe and suck some petrol into it then blow it down the non running carbs to see if it fires those cylinders while it's running on the others. Same deal really, just lets you know if you are not getting fuel from that carb drawn into the engine.
Another quick and dirty check, fire it up for about 15 secs then turn it off, spit on your thumb and touch each exhaust header, soon tells you're which one's have fired.

Turned out to be the condencer now running on 4 cyls, just a few jobs left ready for mot test.
-
Thought I had cured this but now back on 3 cyls, it is definitely a spark problem, one coil supplies number 3/4 cylinders and has intermittent spark on only one lead! It looks like the leads are good but maybe broken internally? how can I check a coil, I have a cheap multimeter but don't know how. Ash will know!

Not familiar with Goldwing Coils but if similar to the in-line fours measure resistance between the two metal parts in the suppressor caps. It should be around 15k Ohms depending on the resistance of the caps (if any). Once you get a stable reading, wiggle both leads and look for an open circuit occurring intermittently. If unstable, remove caps and cut back insulation a few mm to reveal bare new strands and repeat test. If still intermittent you need replacements or my repair detailed here:

-
Mick. One other option to consider is if it does turn out to be a bad HT cable, and it's not broken at the interface with the coil body, you could use one of these to splice in a new HT lead? Saves replacing the full coil unit. Not sure if you have space on the Gl1000 though to do it? https://www.ebay.co.uk/itm/400874941036
-
A coil only firing one of the pair is something i have never heard of, wing carbs can be a swine to clean--nearly as bad as the F2 ones. I would suspect cap and or plug and carb before coil. I also seem to remember the wing uses ballasted coils
-
Thanks for replies guys, I have been in garage this afternoon, decided to replace the original coils and recheck everything. So to begin with I didn't seem to be getting a spark from one coil, when I attached my strobe no flash and that's why I suspected the coil. Then I swapped the two coils over and bugger me the fault stayed the same, it seemed to transfer to the other coil!. Now I suspected the LT side of things so checked each thing then ran the motor each time with no real improvement. I did get a spark on all cylinders and it did run better but spitting and bad throttle response. Really fed up but thought I would try synchronizing the carbs, as Bryan said they are a little different to the SOHC carbs, and as I adjusted the balance between the left and right banks the engine started to rev higher and sounded much better. After a bit of fiddling I now have a much better and smoother bike. Not sure what the problem was but think it was a combination of things. A happy bunny!
-
Now think I'm ready for test, not sure if I will leave it until after the winter as I'm not insured. as usual took much longer than I thought but here are some pics.
-
runs well now
-
Might as well get it insured Mick, classic insurance on that will be peanuts and you'd be covered on fire and theft if you don't already have "laid up" insurance.
-
took Marks advice and insured it £86 fully comp and have booked MOT for Monday! wish me luck.
-
Good luck 😄
-
Good luck

well it failed on front tyre which had a crack in the sidewall and a fork seal that blew on the way so not so bad, had a couple of advisories, rear tyre has minor cracks due to age, I intended to replace both anyway. Ride to test was interesting as it was not running properly to begin with so needed a handful of throttle, not good on wet roads and 15 year old tyres! It did settle down so trip home a bit smoother! Back into the garage again.
-
New tyres and fork seal resulted in a test pass today! nice ride only a few miles but great to be on a bike again, cold but happy!
-
That's great news. Well done.
-
A freind of mine has just bought a very nice K0 goldwing in a very nice original condition !!
Never gave them much notice before but surely is an interesting bike !!
-
Mine has been well used and abused over 70,000 miles then abandoned for 15 years. I have not restored it, just repaired as required and left the rust and grime as it was. Hopefully I can get some riding in next summer.
-
update on this project, as the weather is starting to improve and we get the odd nice-ish day I have taxed the beast and had the odd ride out, runs well and gets a few looks! roll on summer!

That looks very tidy James, is that another import? Very popular bike in USA more so than here, don't think we got the yellow ones in the UK. Missing the grab rail on mine so had to make other arrangements for the rear indicators, the mounting brackets like your bike are hard to find. Are you going to run it or sell on?
-
James.............That Yellow Wing is just lovely. Not a big fan of Yellow bikes I must say....I always liked the early Wing in Black or the Dark Red....but I could find room for that one in my garage. It's in fantastic condition and a credit to it's PO.
Maybe I could sell one of my lovely Daughters to a White Slave Trader (or all 8 of my Grandkids !) and raise some some cash for it (only joking).
-
You can't sell that James, it's a stunner, funny how time changes things, I can remember thinking that they were ugly old buses years ago, same with mk2 jags (sold mine 12 years ago, wish I hadn't 🙁), but that really is a cracking bike.
-
Lovely! The early wings are great looking bikes, I hope you have fun on it.
