Interstate not run for about 15 years

Postby yvesen1 » Sun Jun 13, 2010 11:28 am



Hello everybody,
I bought my first Goldwing Interstate 1200 that has not run for about 15 years.
Its main color is beige.
No scratch on it.
So, I know that it needs the oil changed, brake fluid, cooling and a new battery.
Are there other things to consider before I can start her up?
This bike has 22000 miles on it.
Just one part missing an thats the radio.

Thanks for the help,
Greetz from Belgium

You should not even consider starting it without first changing the timing belts. You'll probably want to have a look at the condition of the fuel tank and filter, too.

Heck in my opinion starting a bike or any vehicle for that matter that hasn't been run in that lenth of time is not an event but a process. You should atleast pull the plugs squirt some type of lubricant in the holes and let it soak for a day or two. And as Admin said inspect the fuel tank for corrosion and rust , and change the timing belts before you even think about turning it over. The carbs no doubt will have to be addressed i.e rebuilt or atleast taken apart and cleaned. Oil changed, coolant changed, To begin with. Check all the electrics and connections for corrosion. And of course a new battery. And after you get it started and running don't be surprised if all kinds of things crop up could be anything. From wild to mild . From big to small

Things happen when a machine that was designed to run just sits. Seals shrink and dry up, things deteriorate from non use. The reason I know is because I had a vehicle that sat for ten years. And if I had known all that was needed to get it back on the road I would have junked it.

Hey,
You're all scaring me here.
I bought this one because the type of engine is so what indestructible.
And she is young in millage.

The previous owner has no manual what so ever.
So, to start at the beginning.
For a GW Interstate 1200 (build??, dont know, color is beige and its an import)
Engine oil and quantity?
Shaft lubricant and quantity?

And okay, the internet is rich, butt a manual for this machine is no where to be found.
Because i'am thinking of doing it all myself, so every bit of help is more then welcome.
I'am a believer, folks
Thanks for everything to get me in the right direction.

:) No reason to be scared . And you are right it is a durable engine BUT it hasn't run in almost 15 yrs . It wasn't made/designed to sit like that. Milage being low is good but even still it has sat . Even if it was brand new you would have some of the same problems. As I stated above it my other post deterioation (age) plays a role here also. If that bike had been running all that time with the proper maintainence and upgrades I can't see it needing anything but MAYBE a stator in all that time and milage appropiate for the years. Sitting is worst that actual riding. Again not trying to scare you . Just trying to make you aware of what you might run in to :D

Okay, thanks for the info.
The leap of faith starts on Saturday.
I'll keep you posted what kind of deterioration I find on this one.
Just hoping to be back on the road soon..

Hello again,

Done all of the above.
All of the fluids changed, even took the carbs piece by piece and cleaned everything.
Butt when I putt everything back together, the bike started on the first push on the starter.
Choke full open, no problem.
Pulling on the trothle then the engine drops down and dies on me.
Even on a full choke.
When you choke down then the engine stops.
When you want to accelerate you have to trottle whit short burst to accelerate.
Otherwise the engine stops.

So, help needed...
If sombody had the same problem, what was the solution.

Thanks a million..

My idea would be to check the fuel pressure . Did you change out the fuel filter ? And did you check the fuel tank for contaminates ? It really sounds fuel related to me! The age of the fuel pump might just play a roll here. So check to see if the pressure is correct :)

As always, thanks for the tips..
I did cleaned the tank and the pump is giving enough fuel.
I found it strange that it only runs on choke, so, could it be the fuel thats not rich enough.
To much air and not enough of the expensive stuff..??
Can you give the engine more fuel whit something on the carbs like a regular car?
I think that it is a mixture problem.

So, after hours of work and headache the bike runs smoothly.


The engine runs great butt at 4.000 rpm no more power, its like the engine suddenly runs on 3 cilinders.
And when I hold the trothle full open for about 10 tot 20 seconds the engine (power) kicks in again.

The carbs are clean and everything is in place.


Could it be than 1 of these sticks and loosen up when the vacuum that the engine gives comes to big to stay attached?

Cant solve this one.

Didn't notice any mention of tires? Don't believe I would venture far on 15 year old tires!

Indeed, tires brand new.
Al thats need changing has been changed.
Butt that 4000 rpm problem gives me a headache.
Bike run fine, lots of raw GW power until it hits the 4000 rpm.
Spark plugs?
Carbs?
Wouldn't know.

Is it a stuttering kind of miss (which would indicate spark) or a bogging down kind of miss (which would indicate fuel)?

I would say "bogging", not slowing down butt no power to accelerate.
Just hovering until full power returns.
Very strange.

When you did the carburators. Did you check the float setting on all 4? Also recheck those vacuum lines.

Enjoy the ride. They are all good, just some better than others.

Pfff, back again, the belgium dude.
My beloved Interstate run great for a couple of months.
Then suddenly no more power @ 4.000 RPM.
So, off went the carbs and i found that all 4 Carburetor slide diaphragms where torn.
Okay, normal?
I think so, after 15 years the rubber was very hard.
No problem, looked and searched the net for new ones.
Found them cheap , a bitt 2 cheap.
160$ for 4 new Carburetor slide diaphragms.
Two weeks later everything came by mail.
Great!
All four went in the block.
And away we went, nice throttle response...all the way.
three weeks later, same problem!!
Damm, reopened the hole thing, yep, same problem.
2 Carburetor slide diaphragms were ripped @ the top where the cover cums together.
Then I looked @ the used materials and found a couple of huge differences.
I was stunned that the new ones have a very thin layer of rubber, the (old) OEM ones are much thicker.
One week later same problem, the others where also damaged.
Send a mail to the company in Raytown where i bought all 4....
Reaction: ALL SALES ARE FINAL
Result?
$190,55 down the drain..

I'am looking to renew the hole set.
Are there people here that bought and used parts from http://www.randakks.com/ ?
Yeah, just to be on the safe side...
Kind regards,
Yves

I bought my overhaul kit from http://www.randakks.com/. Was very happy. I have heard a lot of the others say good things about him.
That or find a used set of carbs to take parts off of.
Enjoy the ride. They are all good, just some better than others.

Im coming in a little late to this post but I too bought 1985 GL1200 interstate last year. I picked the bike up for a very good price. According to the owner it had not been started for a couple of years. IT LEAKED LIKE A SIEVE!!!! I posted the information here and the help I got was outstanding. I just about replaced or had rebuilt everything on the bike. The only thing outstanding is a pesky oil leak from the right hand side valve cover. But anyway.... I say all this to say the journey will be well worth it... keep after it... you'll get there....

I may get cruxified for this opinion, but if it were me I'd LEAVE THE BELTS ALONE. Yep, that's right. Leave 'um alone. All my troubles began with changing out those stupid belts. Been there, done that, really wish I'd not gone there in the first place.

Now, this is the opinion of a guy who's got some mechanical apptitude but not a lot of experience wrenching on bikes (my damaged motor shows that). I can make computers roll over, fetch, and do just about anything, but those (insert expetives here) belts have become the bane of my existence.

Lastly, condition of the engine is going to depend to some degree on environment. There's a big difference between storing something indoors in Arizona and outdoors on the gulf coast... if this thing was indoors in a reasonably dry climate, I'd say do some penetrating oil in the cylinders, then see if you can get it to turn over a little with the plugs out. If that works out, after changing out fluids, give it a go.

Standard disclaimer:
This opinion and a quarter won't by you a cup of coffee.

Good luck with it though!
cheers,

You have found the ONE (but not only) place that can only do you good! Randakk is THE guy who many hold in very high esteem, his site is a wealth of info for GoldWing carbs and many other tips. I have two of his 1200 carb rebuild kits AND a very well written book of how to's and what to expect. He has done very thorough research and he only sells quality parts. I just saw this thread, you would have done well to check his site before you started the rebuild. I'm a bit late on this :oops: But, you can still learn much from him. He has valuable info on how to "bring back" a bike that has been sitting for a long time..just what you need! Go through his site and I'm sure that many..if not all of your questions will be answered. :idea: :mrgreen:

Indeed Randakks kit is far out the best.
Rebuild the carbblock from scratch and used Randakks kit.
The bike started his second life now.
Even deed the timing belts myself, first time for everything and no guts no glory.
Fuel consumption drop t dramatically after the carburetor rebuild (from 7,8l/100km to 5,8l/100km).
Even before I synchronized them.
Not a race horse, butt thats not the bike for high speed driving.

Butt thanks to all, found tons of information on this site, from start to end.
Keep up the good work and drive safely.
