81 Gold Wing Carb Problem

Postby 81Goldwing » Sun Nov 06, 2011 10:32 am



I have fuel spiiting back into the plenum while the bike is running. I've changed the needle and seats, gaskets, air cut off valves and I've adjusted the floats according to the settings in the Haynes manual (15.5mm I believe). There were a lot of extra parts in the Barracuda carb rebuild kit that seemed unnecessary or applicable to different model carbs. I have a video on YouTube wit the the same title. Any help would be appreciated. Thx, John (John@jespecialties.com)

Your problem is that you used a Barracuda (Saber Cycle) rebuild kit. They're notorious junk that either leak, have missing/extra parts, or as you have discovered, just plain don't work properly.

I hate to say it, but your best bet at this point is to buy a Randakk's kit and just re-do the job again with his quality parts. I have yet to hear of anyone who has managed to salvage a Saber Cycle carb kit rebuild.

It's a real shame how Saber Cycle fleeces people who may not know any better into buying their "cheaper" but worthless products.

That's exactly what I had to do with the head gaskets. Live and learn. I'll be ordering the kit from Randakk's. More to come. Thank you.

Can I ask one question? :?:
Did it do that before you rebuilt the carbs?
If it was a pre-existing condition,the rebuild obviously had no effect on it.It may however have made the problem worse.

Not sure what you mean..spitting back into the plenum.. fuel is supposed to spit into it..front the carbs and be sucked into the intakes..so what's spitting where??

It did do it prior to rebuilding the carbs. There should not be fuel in the plenum (air box). This tells me the carbs are flooding. Anyone have extra needles and seats? Randakk's doesn't sell them. It's Honda only.

Anyone have a good wiring diagram for the spark plug wires and coil connections? The Haynes manual is vague. Thx.

Look in the search tab,the ignition wiring is there.I wonder about the spitting gas into the plenum.Even if the carb is flooding ,the motor should suck the fuel on,not out.Do a compression test and check the belt timing and valve clearance.A misadjusted intake valve could cause this.Back off the carbs for the moment.all this work on them hasn't helped.look elsewhere for a problem that is causing positive pressure in the manifold.

Exactly! This is a wierd deal. Adjusted the valves, timed left side, I'll check right side valve timing. I noticed the left bank exhaust is not as hot as right, replaced all four plugs and going to check sprk plug wiring next. Thank you.

Let's look close at this.I might suggest these steps.Mop up the excess gas,leave the fuel lever OFF.Start the bike,it will run a good while just on the gas in the bowl.If it spits a bunch of gas back into the plenum,it won't be due to flooding.
If you can see with a light which hole the gas is coming out of would help.If it' obviously just one carb,then check the compression or vacuum on that one.If the gas is just pooling in the plenum,look for bad O rings in the fuel delivery lines and plenum halves.
It's the spitting fuel statement that gets me.for it to spit fuel backward up the carb,there would have to be positive pressure in the intake manifold somehow.possibly pre-ignition,wrong firing order,or a intake valve problem.

Agreed. I'll try the fuel shut off valve and see what happens. The plug wires may not be run correctly, or I may have a bad wire/coil. All o-rings on the transfer tubes have been replaced.

Sparl plug wiring is routed correctly. I just posted 2 new video on you tube.

Good luck and I hope you figure it out....Sounds like something is clogged...

Are all pipes hot??? maybe one or two cylinders aren't' sucking fuel in..bad valves..or settings.

Leak from plenum gasket or plenum o rings adding extra fuel, dry out plenum, set up alternate gas source direct, plastic bottle with tube direct into #3, put paper on bottom..hold gas source above carbs at least five feet to simulate pressure; paper gets wet from center seam= bad float needles or bad float settings or both and bad gasket or o rings.

flooded bowls..put bike on center stand on level ground, to check turn gas off. drain bowls, take drain plugs out,put/screw 1/4" clear plastic tubes in the drain ports..about 2' long hold tubes up, turn gas on crank engine fuel in tubes should( or use the alternate fuel source described above) rise to just below the lip of the bowls if higher your floats are set wrong or the float needles aren't closing. But should flow out carbs not center seam.

Easier to do all this with carbs on work bench..if this all shows up negative for leaks then it's a jet/choke/valve issue too much gas being let into plenum and or cylinders not sucking it in..

The spitting fuel is probably coming from a plenum leak. What you are seeing is the
action of the fuel pump. My two cents.

Is this the video, it seems like it's as you discribe it.





Please forgive me if this is not the correct video, it's the only one on youtube that matches your issue...Please confirm if it's it..

But did you pull the idle jets? after listening to the video they sound clogged up something bad..

Quick question.After a brief run,can you tap the header pipes to see if all 4 cylinders are firing?
Now ,it won't take long,maybe 10 seconds or so.
It looks like the right rear cylinder is the one spitting back the gas and I would guess not firing.
And the fireball,cool as it looked from here....well that will make you pucker up quick. :o
The only way I can imaging igniting the gas, is if the spark happened when a intake valve was open.
This still leads me to believe that that cylinder has a valve problem,eg..adjusted wrong,bent,stuck,etc.

I suppose,worst case,a timing belt was put on 3 tooth off,cranked the engine,bent a valve on 1 cylinder.
A look at the valves or compression test will tell.
Let us know what you find.Inquiring minds want to know. :geek:

It really looks to me like the intake valve on #3 cylinder is either stuck, or partially open. Watching the pool of fuel "blow around" in the plenum, it looks like it's seeing air being blown back from #3 on the compression stroke - air that's going to contain fuel, that then pools in the plenum. It's also the only thing I can think of that would have caused that fireball.

I can identify with that sigh of exasperation however. I've done that myself many times. :)
