1988 gl1500 what to look at ?

Postby virgilmobile » Thu Nov 17, 2011 1:41 pm



I'm looking long distance at a 88 gl1500.Good price.he says the rear brakes don't work(not a problem for me)and needs the carbs worked on(also not a problem).It is suppose to run OK.
Any tips on things that could be a deal breaker?
Anything I might look at or listen for?

Joining the club, are you? :)

I know the early 1500's had some carb troubles - flat spots and surging, not something you're going to be able to check out remotely. I'd be looking primarily for corrosion - exhaust, inside welded seam of the swingarm legs, and find out of the bank angle sensor was replaced.

You might want to do what I did - find someone trustworthy and knowledgeable about 1500's on the message board and ask nicely if they would check the bike out for you. That went a long way to mitigating any fears I had about buying my bike sight unseen.

Club huh.I thought of it first. :D .
I just been waiting till I sold my 83 first(which hasn't happened yet)before I jump into another project.I finally convinced moma that all good thing come in three's :roll: It's just that the price is really great and it supposedly runs.Just set up a few years in a garage.
From a ways away, I mean this one is a 3 hour drive and I didn't want to take a chance of it selling before the weekend and not knowing the common trouble areas to check.
I can inspect suitability,but I would like to know if the 88 had some bad trouble areas I should be interested in,like frame cracking,or front end trouble,maybe a engine noise,or trans problem.

Mine was 6 1/2 hours...a little too far to go "check out."

I seem to remember hearing about transmission fork problems on the early 1500's, I think in the 3-4 shift mostly. I know the alternators were weak as well. The only really serious problem I heard of was the corroded swingarms (on the insde weld seam, up against the tire).

I can look at the weld areas.The bike is in the DEEP south,so some rust is quite normal.Fork problem...I could try to shift it on the center stand to see if it will go through the gears(not running obviously).I don't think I can run it on the road.Dealing with the 1000,1100,and 1200,I know about weak electrical systems.Does the 88 use an alternator? or still the magnet/stator type?

88 has an alternator. Check the fluid in radiator and check low by filter for leaks. Look for debris on oilstick and check level, low oil and there may be a leak. Clutch and brake may leak at levers. Take a battery and jumper cables to check electrical. Mine set for 2 years in a barn without being cranked and after a few cans of seafoam all is OK. The widower I bought from had very detailed service records she let me see but not have. All she knew was it was a fine ride and her husband had spent a lot of money over the years. Told me what you see is what you get; I drove it home, but did have to get a battery because the alternator was bad.

If mine is on center stand with air fully decreased in rear I can crank and run through gears, but remember to hold down front brake because if you lean back the rear wheel will touchdown. If it does not run you can still check rear swingarm and spin wheel to check brake. Put it in gear and try to rotate wheel to check for excess wear.

Beauty is in the eye of the beholder, if it still looks good and has potential and is priced right you could have a winner.

I have found this link to have some good info for anyone looking to buy an older wing. Someone did their homework researching to let you know what to look out for with the older bikes. There are links at the bottom of the page for all the different goldwings. Nothing beats seeing the bike in person.

Hey virgilmogle I got my 96 1500 in Aug. bet you guys to it, as was said in earlier post check for the recall on bank angle sensor I seem to remember something about the 88's and congratulations on your new to you 1500. You will notice a big difference between your 1200 and the 1500. As Wingadmin has already found when riding in cold wind you dont even feel any wind. I like the vents by your legs that you can change from fresh air to heat. And you know the drill Pics,pics lots of pics. Hal

Nice price. You can't beat that. And what good is a bike if you can't spend a little time tinkering with it. That's why I like used(but not abused) bikes. :mrgreen:

I have a set of carbs for an '88, that when I bought them off ebay, supposedly clean, and ready to go, I was going to use them on a '89, but the gas inlets are different, but I have no use for them, if you can use them, the price is right!

I hope I won't need them.I pulled mine off and just cleaned them up.The bike was set up in a garage for 2years with a full tank.The jets were plugged up and I think they will be OK.I'll keep you in mind if they don't work.Much appreciated.

I'm just getting started on it , so I don't know what I need exactly.So far I've been able to get it to run fair.Still need to remove the 2 year old gas.I've got a electric fuel cutoff valve to replace the leaking vacuum one.New timing belts are on the bench ready for install.I got the EL lighting in the saddle bags replaced with CCFL tubes.

Just a bit of touch up work left to do.
The only thing I am missing is one of the small covers for the left lower and the left upper vent louvers.
Here's some pix.

This response might be too late, but after I bought my '88 used two summers ago, a few small problem areas started to show up.

1. Front forks where low on dampening fluid and therefore caused a "bounce" at slow speeds.
2. Gear shift had a dry rotted seal causing a very slow oil leak. However, after it sat for its first winter with me, the slow leak had pooled up quite a bit on the belly pan causing a lot of smoke when I started it up in the spring.
3. Belly pan screws and nuts where very rusted and over time two of them broke free letting the pan dangle.
4. Finally, the '88s had a factory recall on the "Bank Angle Snsor", make certain this part has been replaced.

Hope this helps! If you bought the bike, at least you know where to start looking for problems:). Oh yeah, as mentioned above, carbs will most like need a good tune up and sync!

My "89 was Martini Beige, as that appears to be, I found a place to order OEM parts fairly reasonable, and I replaced all of the Louvers, and a whole lot of other plastic, changed colors on what I replaced. Surprisingly the louvers were pretty inexpensive, cheaper than used ones on ebay, and the little side covers, I just gave up and bought the chrome ones off cyclemax.

Thanks reasonator ,I'll be sure to check all those things while I've got it in my shop for the initial prep.I still have a bunch of stuff to look at.

Yes Ben,That's the name of the paint.Do you still have a extra left upper louver or where I can get one?

that part is 64455-mn5-000 and it sells for $6.19 at cyclecentralpowersports.com tel number 386-487-0025, I always talk with a salesman whose name happens to be Ben also, I looked this part up on their fiche, and when I was replacing mine, after I found out how cheap they were, I replaced them all, and I threw the old ones away. I found them on ebay used for twice, what the new OEM cost from this place, the only issue is that the shipping will probably be 10 bucks, and it generally takes 7-8 days to get the parts in, but I have always been satisfied with their service, prices and parts. I do still have a side cover, a decent bag, and some trunk parts, they are not great condition, the old bike that I was "restoring" had been rode hard, and put up wet, I replaced virtually all of the plastic except the fairing, so the plastic came from at least a half dozen other bikes off ebay, but today you can't tell it, and the old girl has 148,000 miles runs very good, and has a ton of new parts, either from cyclemax of ohio or the other place listed above. For the condition of your bike as it looks, you got a hell of a deal :D

Not this bike, but another '89 that had gas tank issues (old gas) I used a product called "rusteco" to clean the tank, didn't believe it would work, but when it was finished the inside of the tank looked like new metal. If your fuel pump is still working, then the tank must not be too bad, I had to replace the fuel pump on that one, it was so bad.

Good luck with the process!

In my initial work,I found the bike very hard to start.Crank,crank,crank.I'm expecting that the gas filters and bad vacuum check valve(removed) are the culprit.I'm gonna replace the fuel and add a electric valve this weekend.The carb repair went OK , R & R was tedious but it fixed the idle problem.Now no surging and idles at 800 rpm.The tank is very clean,just very yellow gas.I'm hoping to find a poor fuel flow problem.
I did get a great deal at $2500.The bike was a donation to a Mission to raise cash.Nobody here wanted to buy a bike that the "dealer" wanted $2000 to repair. :shock: Good for me.I've got tools.I anticipate it will cost about $150 in material to get it road ready. :D
Thanks for the contact info.I'll check it out this morning.

Yeah I bought a kit to repair that vacuum valve, then ultimately bought the complet valve, now that wasn't cheap, over a $100.00 but I was in so far already, that I just bit the bullet, I had to rebuild the front forks on that bike, replace the clutch slave and rebuild the master cyclinder, and other stuff.

I looked into the kit..Available from overseas....nope. Replacement..well over $100.
I opted for a electric valve instead($25 + shipping).Haven't put it on yet(this weekend)..I'll tie it , with a relay, to the ignition wire feeding the coils.

What did you have to replace in the front end?I fought with my 83 and 84 with slides and alignment for a while to get them back to normal.Was something just worn out?

Just the seals on the front forks, I actually had a friend do that, and mount the new tires, but as he always says to use the Honda OEM fork seals, I have had to do that on every Goldwing, replace the leaking fork seals. When I got the bike, the bottoms of both rear bags were busted out, looked pretty good except for the bottoms..LOL While I had it stripped down, went through the process of replacing the air shock on the right side, got lucky and found a new one on ebay (new old stock) for $100.00, got the air pump going, thought I was good to go, found out the left shock was the real culprit, first ride was like a rocking chair, went back to ebay, bought an almost like new left shock, replaced, and solved that issue. Cruise control was another issue, that I finally replaced both switches on the clutch side, again found them to be be cheap, and I replaced the right side whole assembly again from ebay. Again, your price for your bike was great, don't know what your mileage is but all of the stuff that I did for that '89 with 148,000 miles, I am afraid to total up the expenditures. The painting of the 43 pieces of plastic, while a lot of money, was still cheap in all of the prep, and coloring both sides and clearing the finished side was $1500.00. I paid $2200 dollars for the bike barely running. Runs and looks great now, but it is still an '89 with 148,000 miles. So I just ride it, It rides as good as the '91 that has only 44,000 miles, little more noise, but still has the go.
I finally gave up on the '89 carbs, and put a set of '93 carbs, on it and don't have any of the low speed hesitation that is common with the 88-89, I have seen a lot of posts and understand that there was a recall on the those bikes for both the bank angle sensor, and rejetting the carbs the bank angle sensor replacement is still an outstanding recall item today, if it was replaced, the dealership was supposed to have an "X" stamped on the frame right below the battery. I have now owned 3 '89s and none of them had the x, I took one of them to the local dealer, and they researched the vin, and said that it had been done, but they refused to X it since they hadn't done the work.

Again maybe too much info, but it might be worth your while to look at replacing those jets in the carbs while you are in that deep.

I looked at the mod specs for the carbs.It's not been done to my 88.The low speed jet is a #50 , the mod uses a #55 ,different needle and slide.I won't know if it needs this until I fix (modify) the shifter sloppy problem.Soon to be posted with pictures of the mod.
