She died again

Postby RBGERSON » Sat Feb 13, 2016 9:40 am



As some of yoiu might remember I was stranded far from home last summer it turned out to be a dead fuel pump which I replaced with a Carter pump and she has been running fine until yesterday.

So on my way home from the store..and she sputters. loses power so I pull off the main road and try to nurse her along. I get a few blocks and she dies..so I loosen the fuel cap..not a big whoose but some, i sit trying to crank her over. She cranks and I get a few sad fires but no real startup, I wait try again nothing..so then I try choking her, full choke, she fires and off I go..I get 1/2 mile and she dies again. So I sit wait push her across the road to a safer spot. Try starting her several times..I get no firing or barely catching for a second or two and not a hearty catch just a cough or two. Then she catches I rev her up to 5,000 and take off..we run the last mile home no problems at high rpms..slow to turn into my street and she dies..I coast into my driveway.

So ideas..I am thinking gas flow issue and will pull the seat get to the fuel line and test the flow. Last time I check everything else first. It was a real pain..getting to spark plugs and carbs etc. Note the fuel filter was clean in August, pump new then too. I also replaced the diaphragm on the petcock a few months earlier it was leaking. But it is a fairly new fuel pump.

Thoughts?? anyone.

Just a thought.Check the vacuum line for the petcock where it connects to the intake runner.
Mine had hardened and cracked.Vacuum loss/little fuel.

I'll check that. Pulled the seat and checked fuel flow before the filter..strong 2oz. in 3 seconds..so no problem with the pump??? Started up sounds fine took a short ride to store 1/2 mile ran fine. As I was pulling into the parking space she quit on her own..came out she started right up and drove home no problems and did not quit as I pulled into the driveway to park.

So now what??? hard to track an intermittent problem but I am afraid to go too far from home in case I get stranded. Yesterday I had been out for an hour or so before the issues started. Mostly stop and go driving on city streets.

Virgin where is that runner connection?? How much plastic do I need to remove, left side?? I assume your are talking about tube #12 which runs down the left side by plug #6?? Have I mentioned how I hate pulling plastic!!! Almost ready to go back to an 1100 just to avoid all the plastic...and electronics!! 8-) 8-)

Many have problems with the non-OEM pump, I would check that first thing.
This is what I do

Yup,that's the hose.Just pull it off the intake and inspect for getting hard and leaking.
If you have verified fuel flow,you could bypass the petcock completely for testing if you think it may be the problem.
You indicate that it sputtered out...This leads me to fuel not being supplied to the carbs correctly.
There's just a couple of areas...
Intermittent power to the pump...or a bad ground
Intermittent pump...
Poorly operating petcock valve..
And one other thing...the grounds.
As I remember reading and seeing pictures,the bike uses a unusual grounding system.Not every part has its own ground wire bolted to the frame
Attached to both sides of the harness near the front of the seat area, there is often hidden a common ground connector block..Just packed full of green wires and using a shorting bar to connect them together to a common frame bolt.I've seen pictures of them with burnt connections.

I'll take a look..grounds, tube, pump and bypass petcock..the part I hate is intermittent, hard to know when/where/what if it's not consistent ...

Before doing a whole lot of tear down, put a vacuum pump (Mity Vac)on the vacuum operated petcock, also called the Auto Fuel Valve. Pull a vacuum to 7 or 8 inches mercury. If vacuum is maintained, its good. If not, that is most likely your problem. I had the same issue once upon a time.

No mity-vac..I have pulled all the plastic of the left side..lots of fun..the number 12 tube is not cracked or hard..seems flexible. While I am there I reset the cruise control per the fix here, adjusted the reverse lever a bit..although I started a thread on that..mine doesn't look anything like the one in the manual..would appreciate comments on the pics i posted.

I have the seat off but don't see the grounding bar Virgin talks about any chance you/anyone can post a pic???

Took another short ride 3 miles each way.. No problem..but it seemed like she stumbled a bit or I may just be being paranoid feeling ever little change or my unsteady throttle?? She started up up, ran up the rpm's well, etc. etc.

Wonder if it could have been a coil issue..got hot and opened up a short?? Would she start and run with only one or two coils working properly..just miss a lot?? Maybe unlikely the issue but I thought I'd put it out here...

Still haven't found a smokin' gun but I just don't trust her. Grounds seem OK I think, no hot spot or metaled tape..hate to cut in and expose all the nicely taped up wiring.

Wonder if Azone loans out a mity-vac I'll call and see. But I did just install a new diaphragm in the auto fuel thingy/petcock.

PS she is looking real sad with all the plastic off her left side.

Do you have a digital volt meter on the bike?
I have one and its attached to the power (black) wire feeding the ignition module.
I do know that the ignition will sputter should that voltage drop due to a bad connection.eg kill switch or other.

If not done correctly that is the problem. The valve needs to be checked with a vacuum pump it should hold vacuum rock solid, then the next test. Remove fuel lines from valve and with vacuum applied blow through valve with breath of air (open), no vacuum applied you should not be able to blow through it.
This is what I do

Your symptoms sure sounds that of starving for fuel.
I know this is redundant but if you have the clear fuel filter it may have very fine particles you can't see plugging it up.
I had this plugged filter issue with my Wing few years ago. From my experience with fuel systems any time you disturb the tank those fine particles go into suspension. Quick check it by removal and tapping the inlet on pure white T-Shirt, need only fuel in it for this check.

Recheck the petcock vacuum. Without a vac gauge, pull the vac hose off the left bank, clean it then draw vacuum via mouth and plug it with your tongue and wait to see if it holds. If it's a pinhole, it will take a while. Or remove the petcock and disassemble then look magnifying glass close. It's rubber, you can stretch it a little without tearing if you suspect and area. We have gone in depth on this, use no sealant to plug a hole, new diaphragm is in order.

Your fuel volume test was to short. A longer one you may see fluctuations or sputtering. Can't beat a pressure test.

I'm not meaning to step on toes of previous posts, different people have different ways of explanations.

Do let us know what you find. We're curious.

I plan on ordering a new filter..just in case. I will try and get a mity-vac and test that.

There's a few 3/8" x 3/8" fuels out there.
Doesn't fit the Wing's holder but does fit under the shelter.
A holder can easily be made.

As to fuel filters, The Randakk's Fuel Filter for the GL1500 is excellent and the price is right.

I check output after the filter and it's as good/the same as before the filter so my filter is not clogged at all. Ilet it run a couple of times it filled a two cup container quickly..under 30 seconds.
