Idea's as to what went wrong?

[7981GS]

Please try to come up with some logical explanations as to what happened.


I was off to the Suzuki store as they were the only ones within 30 mile radius that had 4 of the NGK Iridium spark plugs that I wanted for the GSX. (DR9IEX. Stock #4772)
Cruising along at about 70-75 in the fast lane, Goldy just quit running!
Even KNOWING that the fuel tank was full, I instinctively hit the prime setting on the petcock. Still dead!
As GOD was looking out for me, the entire 4 lanes of traffic behind me zipped by without killing me and I made it all
the way over to the right shoulder.

After a few minutes to let the carb floats fill, if that was the problem, it started right up! But, it was blowing some blue/white smoke now. :???:
When I went to let the clutch out, it bogged down and died. After several attempts to get it running enough to get off the exit ramp,
I ended up pushing it the 1/4 mile to the nearest parking lot.
With a friend coming with bike trailer, here she sits:
(new tag for riding game, in front of furniture store. )

I have a couple of fuel tanks to get out to fellow GSers today and will start inspection proceedures later.
Yes, I will start with pulling the plugs.

Plugged vent hole in the gas cap caused the initial fuel starvation and then all the throttle wringing on the side of the road has fouled the plugs?

Blue/white smoke reminds me of when the gearbox FUBAR'd on a car we once had. You say it bogged and died when you let out the clutch? Your issue might possibly be gear related as well??

You should have settled for "standard" plugs.

This is proof that the expen$ive Iridium plugs are not worth it.

Blue smoke. I don't like where this is going. If that's burning oil, there aren't too many ways to get a lot of oil into the cylinders.

 

[hampshirehog]

Don't panic about the smoke at the moment. If she isnt /hasn't been running well one or more pots will be running rich and rinsing the bores.

I would look at the simple things first. Fuel vent or tap is the obvious start or a dodgy connection in the electrics. Clean the plugs and get it running properly (if you can) and see if the smoke just disappears. Plus have a sniff of your engine oil - could be a bit of petrol has got in there and turned it in to.... - well something that slips past the rings and burns.

Thy petcock is surely dead.
I use to laugh at petcock nazis and now I are one.

A rapid death and a fairly quick recycle time has meant petcock for me in recent weeks.

I also have a pronounced religious belief in the need for new hoses for vacuum and fuel but then we are getting into dangerous ground.

Had something similar happen on my 79GS850. Was running down the freeway around 80-85 and it felt like it was running out of fuel. Switched to reserve No go.. Was barely running. Got some crap/water in the fuel had to do a quick carb cleaning

LOL! Have you tried to replace the plugs on a 1127 engine?
My camera refused to take pictures of the fun...
Anyway, the stock plugs are $5.70 each and the MUCH BETTER Iridium plugs were only $8.00 each.

Petcock and the engine is full of gas.
My guess but you'll have it figured soon enough.

Yes, could be some water in teh gas but more likely something plugging the vent in tank as well.
Now, why resister plugs when there are already resisters in the cap?

After getting the GSX out of the way, I did a little initial inspection of Goldy.
Petcock works wonderfully, no water in a float bowl...
Apparently there was a fire going on in the air-box that fused the boots shut!
I'll have some more time and try to take pic's of the carnage tomorrow.
Looks like Goldy is going to be wearing pod filters real soon, tomorrow.

BTW, the air filter was not touched or even singed.

Some of the carnage:

Being choked to death explains the immediate shut down but,
the cause of the misfire is yet to be determined.
None of the molten rubber made it into the intake manifolds or intake tracts.
I have put over 3,500 worry free miles on it to get to this point.
Not even a hick-up when it quit running. Just shut down.

Congratulations!! You have just shown me something I have never ever seen before.
Now the question is, why?

 

[koolaid_kid]

Wow. I was not expecting that at all. Seems like about the only way fuel could be ignited back there would have been a backfire (no pun intended).

 

[hampshirehog]

I have seen this twice before on 1000Gs ....and you were lucky as you still have most of the bike left. I've got a photo somewhere of the last one that caught fire in the airbox - if I can find it I'll post it and you can see how lucky you were.

However, both those bike caught fire in the garage and I put it down to dodgy float valves. Could be the same reason on your bike I suppose but less likely. I guess you didn't have any problems with it spitting back?

Edit: 3 1000Gs - just remembered one for sale at Netley in 2009. Guy wanted ?300 for it - needed about ?1k spent on it. That was also a garage casualty

 

[hampshirehog]

Wow. I was not expecting that at all. Seems like about the only way fuel could be ignited back there would have been a backfire (no pun intended).

Not necessarily - fumes from the airbox being set on fire by a short somewhere near the battery. Airbox full of fuel = kaboom.

 

[chuck hahn]

You said none of the melted rubber made it into the intake tract..but i still would do a full Berryman soak and reset the float levels. The one air jet and one slide look at least coated in some goop.

 

[7981GS]

Just got back from picking up another 50 carb allen bolts and 25 intake manifold allen bolts.
The carbs are getting a thorough cleaning and jet changes for the pods.
The intake manifolds are getting new O-rings just because.

More later...

[ddaniels]

Wow! That's a first for me too. Sure glad your bum didn't get singed.
