Sputter, sputter ... I can't hear U!

Postby shadow02 » Wed Dec 31, 2014 6:23 pm



Greetings fellow WingNuts & a very Happy New Years to all! I have come up with not 1, but 2 situations that need a resolve on this, the last day of 2K14. Number 1: While riding Big Bird (aka: 1988 GL 1500) today I noticed that she started to “sputter” while holding the throttle at a constant speed. At first it was through 1st and 2nd gear. As I proceeded to ride, the other gears joined in. Not quite a backfire but pretty close. Possible problems? Diagnosis? I don’t think it’s the gas. Situation number 2: This one is less serious. I can not undo the “mute” reading from my radio screen. I click the “mute” button on the handle bars and nothing happens. Again, possible problems? Solutions?

Thanks again and ride safe, ride often-

My first guess would be to check all the plug leads - make sure they have all good connections. Has the bike been ridden in the rain?

Had a Kawasaki GPX600R that would not pull the skin off a custard if it had rained - coughed and spluttered for 20km's before finally clearing itself. Result was from water/coolant sitting in the spark plug holes after replacing a few leaky O rings.

Second guess could well be fuel related - check the fuel filter, and if necessary replace it, and have you run it low on reserve recently, may have sucked some junk through the fuel system? Maybe some bad fuel if recently topped up? I would use some fuel injector cleaner as well - won't hurt it.

That's my limit. I have no answer for your second question. :)

Ok. Just replaced the plugs a month ago but I will check the connections. Fuel filter replaced at the same time but I'll put a lite on it to see if any crap came out of the reserve. This was the first time I ran the fuel gauge down below the "empty" mark but only put 4.6 gallons in the tank. Only use high test in both my bikes so I don't think the fuel itself is the problem.
Thanks for the thoughts-

Are you saying this sputtering just started happening after you ran the bike down to empty?

WingAdmin has the answer for your mute switch, for sure.

As for the sputtering, I still suspect it's a fuel issue. Personally, I'd start with Seafoam fuel treatment. A few tanks of treated gas will more than likely solve this problem.

Also to go with the above comments is that I think there are drain holes in the sparkplug wells. Make sure they are clear so any water can drain out. I haven't been into my 1500 that deep yet but know the drains are on the 1100s.

I changed my plugs around 120,000 (they were still OEM) with lower grade NGK's and mmmm maybe 12,000 miles later I was getting a plug sputter. Ohmed, gapped and reInstalled the OEM's and all was fine.
Any chance you may have damaged the wires end pulling it off? They are rather old and getting brittle.

HOPE ya find it.

You might add half a can of Seafoam to the tank and see if it helps, it certainly won't hurt!

Thanks. Yeah, it's been a sticky winter thus far but we have some cool weather coming in this week.

I would put my money on the Petcock being out of whack! Now that you have us all interested, where are the photos and the cure???

I had a similar problem with my old Royal Star 1300. After pulling my hair out (whats left of it anyway) I ran across a post on a Royal Star forum that I didn't believe at first but found after some research to be correct. Premium fuel is harder to ignite than regular or mid-grade fuel. This is because the premium is made to control spark knock in high compression engines which burn hotter. Because an engine that has a 87 octane rating does not create the amount of heat that a higher compression engine does it takes a fuel that ignites at a lower cylinder temperature. Therefore the higher (93) octane premium fuel does not burn as well or as completely as the lower (87) octane fuel in an engine that is designed to run on the 87 octane. Could possibly be what you are experiencing with your bike.....it was the problem I was having. It would be worth a try to run the octane your bike is rated for for a couple of tanks just to see....it certainly won't hurt anything and it just might solve your problem.

Heading into town one day and I saw a young couple on a Honda 750 on the side of the road, he had the head down what's the problem look as we all have done.
It just quit running he said, just bought her and here we are. hmm, my eyes went right to the petcock and, turn that lever to up and see what happens. Now go get some gas. I did take time to explain the fuel valve operation.
Now, since we seem not to have the top secret clearances, using the S.W.A.G method, I am going for the fuel valve also." Only the Shadow Knows" :)
