Smoking exhaust

Postby TimothyMichaels » Mon Aug 01, 2016 2:41 pm



I've have owned this 1994 GL1500A for only a few months. I do not believe it was doing this and I've put 5 or 6 hundred miles on it sense I bought it, changed oil (HP4) filter, timing belts (hat's off to Steve) coolant and plugs. Plugs were a dark tan/brown with no big deposits. Now it seems as though it wants to blow smoke out the pipes when fired up from cold. The smoke is light gray or white-ish and has the scent of regular exhaust. The smoke is out both mufflers. I bought this bike to take a 4K trip in the last part of August so if anyone has suggestions?

Does it go away when the bike warms up?

Yes, I believe it does go away. Plus I might ad, it does this intermittently. I first noticed it on a morning a little below 60 degrees but, yesterday it did it after not being run for 48 hours. The bike only has 41 K on it although I am not sure of past maintenance save for a few receipts from a dealership. I have the habit of writing down in a log fashion each oil change and maintenance. I do this with the GW and a VT1100C3 I've owned for about five years.

Thanks for your interest.

By any chance do you normally park on the sidestand? If so, that is not unusual with these motors. There are things you can do to minimize it (mainly use the centerstand), or just live with it. No harm is being done, and you are not losing/using any significant amount of oil from this.

Try to make a habit of shutting the engine off before putting the side stand down ....
ie:
    pull to a stop,
    shut ignition off,
    ease bike a little to right as feel for side stand with left foot,
    extend side stand,
    ease bike over onto side stand.


This way you have drained oil out of all cylinders from behind the pistons back into crank case.

My bike was doing the same thing for about 2 weeks only when starting up. It only did it for awhile then the white smoke went away. Not sure what caused it because it never did it before. And it stopped doing it completely. Not sure if it was carb related or something else. The only thing I did differently that I can recall is that I've taken to using Stabil marine grade rather than Seafoam. But can't say if that cured it or not.

I don't think I have found such a neat support group in all my 34 years of riding on two wheels. Thanks much to all. I feel confident again in riding this sled from Seattle to Watonga OK (and back). This ride is at the end of August and getting ready for it has been a challenge. But I've learned much about this bike from it, so it pays well! This website has come in extremely handy.
I will post one more question about faders. If you know electronics you may find it interesting.
I have some music at a website called timothymichaels.net. If you enjoy steel guitar let it be a thank you to all!

Hi,I have owned my 86 Goldwing for just a few months and tho I didn't notice smoke coming out of the exhaust when I bought it I needed to rebuild the carbs cause one of them was bad but since I got it back to running I have noticed smoke when I first crank it up but it does disappear when it gets warmed up,don't think it is an issue for you cause mine clears up. :D

I was about to post the same question when I saw your post. I have a 94 with 34K. same store it only does it sometimes. I have tried sides stand with a block, and center stand. It seems worse the more choke I use when cold. Anyway it seems that everyone is saying it is somewhat normal. So I guess I will live with it. Please let me know if you have found any other information on this issue.

Thanks

I hope you guys are not confusing smoke with steam. My previous GL1500, the '99 did it and my current GL1500, the '98, will also emit a little cloud at times and it is steam. My '03 also does this but is not as noticeable. None of the wings I have ever had actually smoked but I have seen some that would out of the left pipe, and that was primarily GL1200's. They were high mileage and oil would leak past the rings and get into the combustion chamber while parked for long periods of time on the side stand. I have not seem a GL1500 or a GL180 do it yet. Just my observations.

I still notice that it is still smoking when cold. It goes away after warm up. It just turned 34K on a 94. What causes this? Is this valve seals? I can maybe see parking on the stand maybe a design issue with these. But why now why not when it was newer? I feel that this is something that should be fixed. Please let me know what you have heard concerning this issue.

Thank You

Well, my first post was in response to oil like blue smoke. My 1200 did that often when I first got it at only 26,xxx miles but I was always parking on side stand. A stranger saw it one day and suggested I change my parking and so I did and smoke at start up stopped then.

White could be water vapor that occurs as exhaust parts are cold and warm exhaust gases travel through, like why your 4 wheeler drips water from exhaust but which you may seldom take notice of. Water is a byproduct of combustion.

Also, on a GL1200 or earlier, the choke chokes off air. On a 1500, it actually is an enrichener that adds fuel without cutting air.

My '97 GL1500 Trike which NEVER gets parked on a side stand will show a trace of white smoke or vapor as it warms as well .... but so do my cars and PU trucks .... never occurred to me that might be what someone notices. Once warmed, the visable water vapor simply goes away .... though if you let the engine slow on a cool day, you'll still see it.
