1st Time Goldwing Owner

Post by sg4082 » Thu Jan 04, 2018 9:23 pm



I bought a 1988 GL1500 Goldwing from a friend that is having health problems. The bike had sit in his garage for over a year and would not start. I took it home, drained the fuel the best I could, gave it a tune up, new plugs etc., changed the oil and got it fired up. I filled the tank with fresh gas and half a bottle of stafoam (approx. 6 oz). I have been trying to ride the bike as much as possible but the weather hasn't been very cooperative so I haven't even gotten thru the first tank of fuel. The problem is it has a dead spot right off of idle. I know this may just be in the carbs and a few tanks of fuel may fix this. Also, I was wondering about the timing belts. It has 78000 on it and I don't know if they have ever been changed. It's on my to do list anyway. I am thinking this could be the problem with the hard starting issue and the dead spot. What's your thoughts? This is my first bike in 30 years so a lot has changed, ha!

I would definitely change the timing belts, you can find aftermarket ones for a good price. I had bought Gates T275 from eBay.

But the dead spot is a fuel issue, I think. Collapsed or bad vacuum lines connected to the carb, clogged fuel filter, poor fuel pump, bad tank cap, bad petcock, bad carb.slides, dirt in the carb. passages etc. might be the culprit.

Most 88 & 89 wings has a dead spot off idle. You can buy a trigger wheel to advance the timing, do that when you change the timing belts.

Sorry about your friends health and congrats on your new Goldwing. You'll love it. Changing belts a good idea (mainly due to rubber belts and aging). But dont think that has anything to do with off idle stumble.

The off idle stumble sounds normal for a bike thats been sitting. Its good the carbs aren't too gummed up. I've experienced it too when my bike hadn't been ridden enough. Sounds like you did the right things. Maybe change the fuel filter. And be patient, you'll need to run a few tanks thru it regularly for it to clear up. Once decent weather comes back dont be afraid to dump an entire can of seafoam in there (actually just half a can since you already dumped half of one in there) with a full tank of fuel and run it thru. Then add the recommended amount of seafoam (it should say on the can) for the next few fill ups and it should clear up the stumble. 88's and 89's did have a recall for off idle stumble but would guess yours is worse because the bike was sitting for awhile. Personally I found that marine Stabil works much better than seafoam but its just my opinion.

Good luck with your new bike and post some pictures!

Today was the first day it's been around 50 degrees so I filled up with fresh fuel and the other half a can of seafoam and took her out for a ride. This is the first bike I have ever owned that was fully dressed and I am really surprised how I can ride it without freezing even when the temperature is down around freezing! Pretty cool, ha. Anyway, I have changed the fuel filter already because it was weeping fuel from it and I thought that may be part of the hard starting issues. I am just about convinced that the off idle dead spot has something to do with the sliders in the carbs so tomorrow I am going to pull the top of the tank, radio and other stuff to gain access to the air filter and the carbs. Going to do my best to clean them without actually having to pull them off, may work may not, we will see. The timing belts are right at the top of the list. I read the post last night on the timing belt removal and I think I am going to give it a shot. Worked on fighter jets for 35 years and own/race a rear engine dragster now so I might be able to fumble my way thru this.......I hope, lol. Thanks for all the information, it really helps!

Without reading 30 pages of posts on the trigger wheel, what is it? Is it like advancing the cam on an engine? Ok, just looked it up on the web. Seems simple enough, just like advancing the cam.

Oh, and thank you for my friend. I raced with him for many years and Brain cancer has gotten a hold of him. He's fighting the good fight though and we are hoping for the best.

No, it advances the ignition timing.

Those who say it cannot be done should try not to interrupt those who are doing it.

Well, I was going thru some of the paperwork on the bike and found the manual that came with it new. Looks like the timing belts were changed at 66,000 miles, but it was about 11 years ago. The bike now has 78,900 on it. My question would be should I still plan on changing the belts or just go with it? If I go as far as pulling everything off to inspect them I might as well change them, what's your thoughts?

If the timing belts only have 12,000 miles on them, I would leave them be for a year of good riding, and use that for next year's winter project. The mileage would be about right, and the years are not a problem.

Once you get the tops off the carbs, use some carb cleaner in a spray can, and wet the slides down a bunch to wash out the grit that is most likely causing the problem.

On my '94SE, the left slide quit working.... and when I removed the air cleaner top, pulled the air filter, I could see a 1/4 inch gap between the bottom of the air filter housing and the top of the carbs....

Some bright mechanic removed the gasket and never put it back.
Also, he left the hose loose on the lower right front of the air filter housing. Talk about noise, there was a bunch of it...

Funny how it works like it should, when the gaskets are installed, the slides are working freely, and the hoses are all connected.

Funny you mentioned that about the noise. I pulled the air cleaner when I first got the bike last week and when I finally got it started it sounded like it had one hell of a vacuum leak. In the forward right side of the air cleaner box there is a formed hose coming thru the bottom of the box that is just open and sucking air like mad. I didn't know if this was normal or what. I am going to check into this further to see what's up. It's definitely sucking vacuum because I took a piece of paper and put over the hose and it stopped leaking. Any thoughts on what this is?

Normal, if you rise rpm a bit it stops sucking air.
Look this video, explained operation in the end


I believe 88-89 models are similar by the parts.

That hose on the lower front side of the air cleaner housing will cause a heck of a lot of noise when it gets left loose. It doesn't hurt the running of the bike but it sure does cause an irritating noise. It is kind of hard to get it connected back also. It is a real bear to get connected back up unless you pull the right side fan out. Then you can just reach in with your hand and put it back in place. Of course, getting the fan out and back in is no easy task either, but at least you can get the hose back on.

It May be fuel vapour coming from the carb over flow pipe. the vapour smells are funnelled up through the body panels and come out from the fuel cover or the gap by the forks. when you park up have a look under the bike to check the hose. it will be damp on the end and you may see the vapour trail
