My Attempt at the Fixing the Horrid Fuel Smell

[Bob Denman]

Would you suggest a proper heat shield surrounding the fuel tank, and wrapping the exhause pipes? :dontknow:

I have both and still have boiling fuel and fumes.

In that case; my untrained gut would say that you need some airflow under the plastic, to clear out the excess heat! :shocked:
What do you think, are your best options? :dontknow:

I have wrapped my exhaust pipes and recently added additional heat shielding to the tank but I honestly don't think it's going to help or very little at best. When I was in there adding the shielding to the tank I noticed that the plastic sleeve covering the wires to the brake switches was melted, wonder if that was the "burning plastic" smell I noticed a few times?? I was really hoping that the 2013-9 update was going to be a game changer for us but I guess not. Another season of continuing problems.........

I have the panels coming for one.

Also have JTs air filter in the garage which should clear up some space.

Also looking at an Akropovic for increased flow (and hopefully a little more performance w the air cleaner)

Not that my bike is that hot, but these performance mods may also help w any future heat issue. :thumbup:

Oh...and add some hose between the tank and canister.

Your always going to have some instances of boiling fuel due to the design. Fuel can boil at a pretty low temp, and ethanol even lower, so having a hot motor/exhaust real close to the tank, it would be expected. You would either need to relocate the tank, significantly change the exhaust routing or change the motor with an inline to rout the exhaust out the front then down and under.
Boiling fuel happens on a lot of platforms and is not totally unusual. Also, keep in mind that canisters and purge valves are not common place on motorcycles either....,

:agree: Mount that baby under the Tupperware, and it'll clear up all kinds of space... in your garage!! :roflblack::roflblack::roflblack:
:lecturef_smilie: Git 'er done!

Because the fuel boils after the engine is stopped and the canister becomes inundated with fumes that return to liquid gasoline

Problem is, it happens engine running or not. The fumes are BAD sitting at a traffic light.

"Due to the design"

I keep reading the above statement in posts here, so this is clearly a BRP problem they need to address, fix, and repair for all on their dime.

Waiting for new panels to hopefully do it all at once, getting tired of taking panels off every other week.....maybe I should just leave all the panels off...then i wouldn't have any heat issue at all. roflmao

Finally had a chance to ride it after the "repair". I filled the tank and was very careful not to "overfill". Hit the brakes hard a couple times to see if I could force any fuel up into the first filter. Then I rode for about 45 minutes. Low 70's temp.
Opened the seat and checked the filters.

The first filter had some gas in it, Keep in mind that the filter is a couple inches higher than the highest part of the factory line.

No liquid fuel in the second filter..

The gas smell is greatly diminished.

I think I will keep having the gas odor until my canister dries out. Also it was much cooler today so heat might not be as much a problem.

I am pretty convinced that the factory tank vent hose allows raw fuel to pour into the Evap Canister when hitting the brakes with a near full tank. Overfilling is NOT the problem. BRP needs to fix this!

 

[Bob Denman]

They did...

 

[Craniac]

I'm glad they fixed it for '14. They need to fix for previous years.

I wonder if this has anything to do with my abysmal gas mileage. Mine radiates heat and vapors all the time, and all the while I'm imagining nickles and dimes floating away through the air as it does so...

 

[Bob Denman]

Could you have a purge valve that's acting a bit wonky? :shocked:

Gas fumes and mpg

If you want to stop the gas fumes wrapped the modifold pipes. It will stop the boiling of the gas plus keep it cooler under the plastic. What helped my mpg beside cooling the compartment was changing the air box to a new 12" round air cleaner. Now I have more power at 3K rpms then I did at 4K+ rpms. my mpg went from 20-27 to 28-36 and no more strong smell of gas fumes. RJ :2thumbs:

Did you do anything with the cat like wrap it or remove it? Seems like that is a high heat source right under the gas tank.

Craniac, Interesting thread you started and thanks for sharing. I was thinking the same thing for those who are having this problem. To run the vent hose as high as possible before looping down to reduce or prevent liquid gas from entering the canister. This should add some evidence for against if it's an overfilling cause or contributing factor. The clear gas filter is a great idea. What was your thinking for the extra loops of hose around the frame?

Depending on your results I may do the same thing. I have not had any gas smell issues on my 2013 ST, but it would be easy, cheap insurance. I do know what it's like because my 2009 GS would smell from time to time.
