New to me '83 1100 Aspencade

Post by WTF »



New guy here, not new to riding or wrenching--but for sure new to Goldwings.

A friend of a friend gave me an '83 Aspencade. Complete and remarkably nice for having 111,000 miles and living outside (under a shed) for the last 10 years. A little frame rust and a lot of the usual old bike issues.

Of course it was "running when it was parked", aren't they all?
It had about 1/4 tank of gas which was nasty sludge. The parts that wasn't sludge was crusty rust.

Cleaning the tank and carbs was first priority so I could determine if it ran good enough to put time and money into.
Started by trying to remove the rear wheel so I could get to the gas tank. Easier said than done because the rear brake caliper mount is seized onto the axle, seriously seized, and being a single sided swingarm I didn't want to beat on the bolt--any harder than I did.
So I disconnected the drive shaft and pulled it off as a single unit. Still have to deal with that...

Pulled the gas tank and carbs. Cleaned the tank--soapy water and the assortment of bolts to break it up. Then electrolysis to pull out the rust. Then a light coating of 2 stroke oil to keep it rust free until it gets reinstalled.

Stripped the carbs down to 4 shells and soaked them in Pinesol to clean out the crap that blocked every orifice. Made sure it was spotless and rebuilt them with the to-good-to-be-true $29.00 carb rebuild kit from ebay. I was suspicious of the quality at that price, which was justified. Not enough of the O-rings to reassemble the 4 carbs into 1 unit and of course the accelerator pumps did not fit.

I sanded the acc pump shafts enough to get them to fit and used the best of new and used O-rings to reassemble the carbs and mounted them back on the bike. I used a remote gas tank, flushed the fuel pump and hooked up the fuel lines.

After a few minutes it did start. It is ROUGH, but running. But the accelerator pumps do not work, if you turn the throttle too fast it bogs or stalls all together. Slowly turning the throttle will let it rev thru 3K RPMs, which is about all I wanted to do with it sitting on the center stand with no wheel, swing arm or drive shaft.

Also, at least 2 of the carbs leak gas onto the case. Could be the O-rings between the carbs, could be the bowl seals, they were really thin compared to what I usually see. Could be that it leaked before, I wasn't the first person into them. I don't know why, but they do.

I shared all that to ask about the single carb conversion.

The price of OEM replacement parts is crazy high and I am frugal by nature.
The single carb looks like a good replacement option soI ordered an intake, I hope it works as well as he says...

Next I will be looking for a carb. Does anybody have a good recommendation?

Randakks is the source for quality carb parts. If they were as bad as you say, it might take an ultrasonic bath to get them to work properly again. If you have the pressed in idle jets, they may have to come out, too.
You might want to research single carb threads. While they have worked for some, there are a lot of issues and they will never run like the stock setup.

If you do want to go with the single get a real Solex and not a Chinese knockoff. You will still have to re-jet and fool with it to get it running ok. You may need manifold heat to keep the carb from icing up in humid conditions. For all the work involved and the fact that in the end you will still have a carb, I would either go to fuel injection (if you want a project) or just fix the stock carbs.

I think you have three choices. 1.Overhaul the original carbs correctly, 2. become a design engineer and put on a single carb. , 3. get rid of the bike because it is going to cost 1500 to $2000 to get it running reliably.

Not only the carbs but hoses, belts , water pump, the entire brake system, coils, etc. Will need to be replaced to have a safe and reliable bike.

Overhaul the carbs correctly. 2 choices, DIY or send them to a pro. There are two overhaul manuals I'm aware of. Randakks and The Motorcycle Project, these are step by step guides to assist in the correct techniques. Buy the Randakks parts kit. It has everything you need and the are known quality parts. There are numerous air and fuel orifices that need cleaned ultrasonically and with aerosol carb cleaners. I had to take the carbs off several times because the accelerator pump circuit was gummed up, had to use a small butane torch to clear them. There are many professional carb rebuilders that can rebuild the carbs for you correctly at the cost of time and of course money.

Installing a single carb is not an easy task. Which carb, how to design and install the throttle cables, design a new intake, air filter design, how to get gas to it, design a choke system, then you have to jet it correctly. Idle jet, main jet, idle speed, etc. And then after all this effort it may not perform as well as the OEM carb setup.

You can get this bike running well with the OEM carburetors. It's going to cost close to $1500, that's why people are giving these bikes away. If you are mechanically inclined and have some spare time you can have a great running vintage bike.

I guess I am "becoming an design engineer" because I am well on the way to attempting the single carb. The intake showed up this morning:









The 34PICT 3 carb will be here Thursday, then we will see :)

Made some actual progress.

I used a buddies press to get the rear axle out of the rear tire and swingarm. It was really stuck. Grease those axles before you put them back together.
Got the rear cleaned up and back together. Changed the gear oil at the wheel. Replaced the boot at the u-joint--that was a PITA.

It actually runs decent with the VW carb. Starts easy, idles nicely. So far I have only been around the driveway 2 times, but that is enough to get me fired up to do more.

And there is so much more to do. I have no brakes. Rear disc has lost 3 bobbins and a couple more are loose. Those suckers are $30 A PIECE! So new rear disc coming soon. Thinking seriously about re plumbing the brakes so that the rear pedal is just the back and the brake lever is both front at the same time. It is weird now.

The compressor doesn't seem to work so suspension is not aired up. I have not looked into it yet, but old school spring shocks seem way easier.

Valves and timing belt for sure

Next step is a battery tomorrow. I left the fuel shut off solenoid on the carb so as soon as the 12v goes away after jump starting it it cuts off. Nothing like a test ride with the battery in your lap--on top of the gas tank!





My wife says I am the Hecks Angels :lol:


1st trip around the driveway--just sharing the view :)

Still plugging away on this thing.
Single carb seems to have solved all my starting and running issues.
Valve adjust helped a good bit with smoothness.

Picked up a set of brake hoses yesterday to convert the front brake plumbing so that both sides work with the lever. Should know how that works out this afternoon.

This is the kind of mess I am dealing with now:





What really happens if you leave the weight that was covering this mess off? :lol: :?
