Restoring 1987 GL1200 to roadworthy condition

The pump is eBay.

I agree Dave, I crossed the OE part number and the pump on my bike says it is compatible. I'm going to remove the carb and check the float and float Needle to see if there is an obvious blockage. If I don't see one I may try to source an oe pump, however they seem rare and expensive.

Dennis do you think the OE Honda pump is even available? I did a quick check and every one said it was out of stock

No, the pump for the '87 has been out of stock for more than 10 years probably. I have a spare, but I'm keeping it.
Unfortunately, most '87 specific parts are no longer available. The seat on yours isn't correct because they ran out of them long ago, as well. I can't offer any sources, but surely, someone out there is parting an '87. You just have to be vigilant.

In the mean time, you could put a cheap used OEM from another year on it, with the stock relay it would work. You'd just have to rig a step-up for the hoses. The early ones had smaller ports. The one you have now may be small too. It looks like there are hose clamps on it.

I just looked on eBay and didn't see anything cheap enough and there's even a rusted out aftermarket one they are claiming is OEM, so you have to be cautious. Where are you located?

It sounds like you are certain the oem pump will work the best, so if I find no issue with the floats I'll source an 85-87 and rig it up, I'm in charleston, sc. was hoping to enjoy the summer on two wheels instead of four, guess we'll see!

Just measure your fuel pump output pressure. If you don't have a gauge, you can just use a length of hose. There is also an output volume spec in the service manual.

Imagine that.

Ethanol needs to go away.

Floats can also leak and fill up with gas, so they no longer float. I've had a couple do that. On the second one I just replaced all 4.
While you've got the carbs apart it would be a good idea to replace the o-rings. OEM kits are cheaper and of course better quality than aftermarket. Jets clean up easily.

What solvent do you recommend to get rid of all these deposits? There is a good bit of gelatin as well as harder deposits stuck on the inside of the bowls. Seafoam time?

I'm not a fan of Seafoam. But some like it.
Maybe there's an answer on here somewhere.

I'm guessing these two are most pertinent.

Mostly, I'd guess that one of those spray cans of carb cleaner would work just fine, but...

Berrymans B12 spray is as good as it gets for aerosol cleaners. Do not get it on rubber parts, especially the slide diaphragms. Be sure to remove all the jets and the mixture screws and make sure all the internal passages are clean. All the original brass parts will usually clean up just fine.

after all the trouble about pump and pressure, and we see the carbs had never been inspected.

Thanks Dave and Dennis! I'll get her cleaned up and synced, might even be on the road by sunday!

They probably need an ultrasonic bath or fine wires and compressed air to get all the idle passages clear again. It's not really an ethanol problem, more a lack of use problem. Now the rubber parts going mushy and decomposing, that's an ethanol problem.

For mine 85 Aspencade I've installed a fuel pump off a 1985 HONDA PRELUDE 1.8L L4 (carb). Found it on Rockauto. It has a working pressure of 2-3.5 psi which is perfect. Right now they have a CARTER P70213 available. I do not remember being any difficulties installing it. Hoses fit, mounting also was somewhat close. It's been 10 years ago...
