Exhaust Fumes Smell Gasses While Riding

Postby carlrf » Tue Sep 24, 2013 12:18 pm



:( :( Howdy, I am getting exhaust pulled into the cockpit while riding, very unpleasant, starts headache, etc.
Intensity varies some with speed and passenger or not.
I am a new member, with new to me GL1000 w/Vetter windjammer fairing and bags.
1978 with 19K miles. Bike is probably an 8 out of 10 on condition.
No rust, exhaust looks to be in good shape too.
I am 57, been riding since 14. ~ 190 pounds. 5'11" well I actually think my spine and joints have settled to 5'10"? Anyway.
Years ago I had an 82 I think with all the Honda fairing and bags, did the same thing and I put a new Mac exhaust on it front to back and it still did it, so I sold it. Hated riding it because of that alone.
Bought this one after a slow test ride and fooled myself into thinking the Windjammer was gong to be different, not.
I am trying to like the bike, as it is in great shape, black, running good, etc. But if I can't fix this it's going on the block.
The seat is a king queen tour seat that I suspect is considerabley lower than stock. I am shopping for an original seat to get me taller in the saddle so I am looking over the windshield (which seems to help) but not sure that's the answer.
Searched forum but didnt find much that applied.
Your help is greatly appreciated, but no, I can't send you money, sorry!
Carl, Kansas City

I've been on a lot of different bikes over the past 40+ years...very few had this problem and the ones that did had a altered exhaust system,exhaust leaks or added junk bolted to it....
.....I assume there are no leaks...

My contention is simple....
If it's OEM , the exhaust flow dispersal has been designed into the bikes aerodynamics...
That's why you see different types of exhausts on the same frame outfitted with different accessories(OEM setup)...

When saddle bags and faring are added,it changes the air flow around the bike...the exhaust should also be altered as well...Moving air helps carry the exhaust fumes away from the rider....

In your case...as I can only imagine in my mind...you may benefit greatly by adding a extension to the tip of the exhaust with a "turn out" pointed away from the bike at 45*....

Try anything that may improve the air flow down the exhaust pipes...
You might be surprised what a simple air deflector can do too...

How bout a good profile picture of your bike...Perhaps somebody has already solved this.... :?:

A quick look at Advance auto yeilds something like this....
Try one long enough to get the exhaust out from under the bike and project it to the sides....
This will not affect the exhaust system overall...just re-direct it.

I usually listen for leaks....A piece of long 1/2" hose(or garden hose) as a stethoscope...
The most common areas are the coupler joints and at the heads....

Also 2 people...One to listen for leaks while the other restricts one exhaust pipe at a time with a rag...

Great info, glad I asked.

BTW I really am surprised a search didn't bring this up.
Another wing I test drove last month did exactly the same thing.
I noticed it in less than 2 miles of riding slow/moderate speeds.
I have had several bikes of various sorts and never encountered a problem as this, especially so consistant and repeatable. Obvioulsly there are going to be times and situations when the wind is just right to blow a wiff or two but that is not what this is.
I hope I can cure it.
I would hate to cut the rolled ends off my stock pipes but???????

This isn't my actual bike, but it looks exactly like it except with a black front fender.

About the rolled end...My 83 had them...it also had a turn out extension...It fit over the flared end just fine...Where it clamped to the existing tip,there was a spacer..looked like a rod bearing...It took up the gap to keep the extension centered.....Take precise measurements before buying one...
Better yet...Drive the bike to the parts store...Ask if you can try one to see if it will slide on and look OK...
Mine also extended the exhaust right to the end of the saddle bag...
Your probably getting some turbulence there and the exhaust is getting pulled into the rear fender well.

WARNING...this is my opinion only...general disclaimers apply to free advice.. :D

I agree with Virgil as none of the three Wings I have owned have had that problem but all of them had turn down pipes. Myself, I like to ride because of fresh air, not exhaust fumes. Besides, it's bad for your health, gives you headaches, makes you fall asleep, not a good idea on a bike. Ride safe.

Just a follow up. Fumes not quite as bad as when I posted for some reason.

But, I can actually feel wind hitting my back and back of neck.
That at least explains why I am smelling exhaust.
Now to try and correct the airflow? :(

I went to autozone and got a pair of extensions.i turned them outward a bit.
The ends are right at the rear of the saddle bags.
I did not cut anything off the exhaust to fit them either.There just extensions.
