muffler smoke

Postby mermco » Wed Mar 16, 2011 6:25 pm



Hey all, got what to me is an odd deal. I get smoke from my right side exhaust after I have turned the bike off and walked away. It also has an odd odor like something burning. Anybody got any idea what's goin on here? Is the muffler shot or just full of carbon that burns when things get hot? Any thought would be appreciated. The bike is a 78 gl1000 with about 30,000 mi.

Does it happen if you park it on the center stand and leave it a while? If not, then you are witnessing how Gold Wings mark their territory, or fog for mosquitoes. If/when you lean it over on the sidestand immediately after shutting it off, oil will settle in the left head area, and if a valve happens to be resting in the open position, some oil will find it's way into the cylinder head, ready to be burnt as an offering to the motorcycle gods once it is restarted. I quite often avoid that by shutting off the motor, then just sitting on the bike in the upright position while I take off my gloves, unbuckle my helmet strap, unzip my jacket, etc etc before I lean it over on the sidestand. This lets most of the oil drain where it is supposed to, thus minimizing the smoke.

If this is your experience (the smoke), then I am also assuming that the reason smoke comes out the RIGHT side might be because exhaust from all 4 cylinders enter a common collector before splitting and going to both sides.

Others will no doubt chime in here, and correct me if I'm wrong.

Hmmm, after re-reading your post, that odd smell might indicate a head gasket issue. Again, others will no doubt be jumping in here soon. Stay tuned. :)

It's a bit odd that the smoke is coming out AFTER the bike is turned off. Are you sure it's coming from the inside of the muffler? Can you tell what color the smoke is?

Thanks for the advice so far. The smoke is definitely coming from the end of the right side muffler and smells a little like burning paper and is a light gray in color. Is it possible this is just carbon build-up in a 33 yr. old muffler? These are the oem exhaust pipes. Going out to check the coolant reservoir for any signs of oil contamination in an attempt to rule out a head gasket issue.

It could be carbon buildup, yes. I kind of doubt it's going to be a head gasket issue - any coolant is going to be vaporized into steam long before it gets to the exhaust, and won't be coming out after the engine is off. It will also smell sweet, not like burning paper, and will be white.

That sounds like good news to me. I wasn't aware of the sweet smell that is good to know. I have checked coolant and drained the oil to check for contamination and didn't find any. Will keep on riding and see what develops. Will let you all know how thing go. Thanks for the great info.

I had a mouse build a nest in my exhaust tip one weekend, lucky for him he wasn't home when I started the bike. Most of his nesting materials came flying out but some remained and burnt, smelling like burnt grass for a ride or two.

I will check and double check for varmints in the exhaust. I am out in the country and the bike is covered but not always garaged. It would be funny to see a mouse come shooting out the tail pipe.

Turn off the gas let the engine run for a couple of min.then stop the engine,no more smoke means you have a float that is stuck or not set right or a bad needle and seat.To check this when you see the smoke pull the plugs to see which one is wet.

Okay all, new development. Pulled a plug from the right side of the bike and found the plug hole full of water. I am assuming that means a head gasket issue. Is this a repair that someone with an average amount of mechanical experience can handle? Are there any tricks that make it easier to do or pitfalls to avoid?

Go to Randakks.com and read the info he has,This job is not hard to do,I suggest you also change your timing belts and thermostat,The main thing is something caused this to happen and you need to find out what it is before you do this work.These gaskets dont blow for no reason,Make sure you get the PROPER GASKET for the gl1000 as they are different in thickness.If you dont use the right gasket it will never run right.Be sure to visit Randakks.com and I would order the parts from them.Good luck.Joe

If the water was on the outside of the plug hole, it is probably just a drain hole plugged up. Take a stiff wire and push it through the little hold near the spark plug. It should go all the way through to where you can see the wire hit the exhaust flange. Water here can also short out the plug.

My 75 does the same thing. I just always leave it on the center stand.

Are you saying the cylinder was full of liquid? Gas or antifreeze?
Is fluid missing from your cooling system?

Thanks to all who have posted replies. Yes, the cylinder was full of water. I have raised the white flag and taken the bike to the local wing guru. I'm waiting to hear the extent of the repairs that he recommends. I'm sure a head gasket is in the mix. Hoping that is the worst of it. This is a really nice old naked '78 and I am determined to be on it again soon.

Thanks to all. Problem finally revealed itself to be a bad head gasket. Took it the local wing guru and am picking it up tomorrow. Happy to have it back.

That's the prettiest blue I think I ever saw on a bike, I am now considering repainting my bike using that color blue, with the same black accents as shown in my photo there..I alway loved that blue..

Seeing a white vapor from both pipes on my '89 1500.
A little history....new purchase, just did a rebuild on the carbs (Randak kit), replaced a thousand feet of tubing, fuel pump and changed the air filter and plugs. Still have Seafoam in the tank, wondering if that might be breaking down some carbon build up and causing the vapor coming out the pipes?
Also, have flat spot when throttling up, going to do a sync tomorrow hoping that will help?
Guys, this site has been a saving grace for this "project" of mine. Thanks in advance for all of your contributions and advice!

A bit of smoke during a cold start is normal, especially if you park it using the side stand rather than the center stand. Oil finds it's way into the left cylinder during cooldown. All bikes with "flat" or opposed cylinders can do that. You can somewhat minimize it by waiting a minute or so after you shut the bike off before leaning it over on the side stand. I take that time to take my gloves off, unbuckle my helmet, take off sun glasses, etc.

Regarding the off-idle flat spot: Your Seafoam treatments might help if the bike sat for a while before your purchase. There was also a recall on the early 1500s to replace faulty Bank Angle Sensors (tipover switch). I think there is more on that elsewhere here. Others might also add further comment. Enjoy your 'new' ride.
