Air filter box

Hello fellow spyders!

ive been noticing a strong fuel smell coming from bike
it comes as soon as I turn it on and continues throughout the ride
its an 09 gs / sm5 I have about 8k on it

after reading threads on this amazing forum I ordered the Honda y gaskets
so I started tearing down the bike to see if this is something I could do myself (gaskets should be coming soon)
i opened the air filter compartment and to my surprise this is where the smell is coming from!
i noticed some oil deposits in some areas and the k&n filter looked clean

im not mechanically inclined but willing to explore
what do y'all think is going on ??

any help in the right direction will be appreciated

thanks
all!
 
For strong fuel smell right from start up I would look for a fuel leak in the coupler on top of the tank. Does not happen often but has happened. If there are no leaks then are the fumes coming from the canister vent? If so likely a purge system problem.

Exhaust slip joint gasket failure will cause a hot right and backfiring when letting off the throttle not a fuel smell. Yes go ahead and replace with Honda gaskets.

You can also get fuel leaks in the high pressure system. If you don't want to burn you Spyder to the ground you need to find what is leaking and fix it.

You can also get fumes from an overloaded Evap Canister. I recommend getting rid of the Evap system. But if you don't want to do this at least get it working properly. You may have to replace the canister. But if this is indeed your problem, you need to find out why the canister is overloaded or it may fill up again the day after you replace it.

Good Luck! :thumbup:
 
I had a strong fuel smell on my 2008 GS
Found cracked fuel filter did not leak unless engine is running
I had about 10,000 miles at the time
 
All of the above...

check the fuel filter as well. if the filter was changed and they went with different clamps they may be leaking...:thumbup:
 
Thx for all of the info

i don't visual see a fuel leak
just in the air box I smell it strong and there is also some oil

can y'all provide me with a link of how to fix this problem ?
 
I want to start off by doing the caniserectomy
i don't know a lot when it comes to the mechanics
i have my spyder torn down with all the panels removed

Stumped on where to begin

You're lucky I happen to have the panels off that side of my Spyder so I'll nip out and take some photos for you. Back in a few minutes and will post them.
 
Here you go.

Firstly you'll notice I've got one of JT's air filters on mine which gives you so much more room when doing your own maintenance - works a lot better than the stock one. Finding oil in the air filter is pretty common on our older model RS/GS's - from memory you can solve it just by lengthening a pipe, I'll try and find the info for you and post it - Having a JT air filter means I don't have that issue:-)

Anyway back to the Canisterectomy photo's.

Removing the canister just means unplugging the two pipes that go into it and unclipping it from the mount. Mine was held in place on the mount with a cable tie but I'm not sure that was normal. I ended up cutting the two pipes going into the canister as I had trouble removing the pipe clips without damaging the pipe.

Once you've got the canister removed you just need to:
  1. Block off the canister sensor pipe (1), which I did by screwing in a bolt with sealant in the thread and putting a clip on it.
  2. Extend the gas tank outlet pipe (2) by adding an inline fuel filter to stop dust etc going up and running an extra pipe so it goes out beyond the floor pan of the Spyder (basically so it vents outside the engine bay). You can see on mine I've run it to a pre-existing hole in the pan forward on the engine and made sure it had shielding on it.

Sorry for some reason the second photo will not upload as portrait.

Yep no worries.

The other thing that I've not noticed mentioned in this thread yet concerning the fuel smell is the gas cap. There were issues with the earlier Spyders and a strong gas smell. This was often the canister (hence the canisterectomy) but also there were issues with the early gas caps.

Not sure how long you've had your Spyder but BRP did a recall on the gas cap in Jan 2013 and hopefully you should have the replacement fitted already. However with the replacement one there have been issues with it breaking and not being able to remove it (I've had this problem). There is a replacement you can get made by Stant which fixes both issues. There's actually several Stant models that work and if you search this forum you'll find the various part no's but the one I used was a Stant 10819 (got it from eBay).

The gas cap replacement and the Canisterectomy fixed my gas smell issues.
 
PS Just remembered I think there's three pipes that go into the Canister not two but ones a vent pipe so that just gets discarded.
 
When I unclip it what do I do next
it looks like there is a plug that joins

Don't touch that part as that needs to remain. If you follow the pipe down from that you'll come to a big thing that looks a bit like a drinks bottle with three piipes going into the top - that's the canister.
 
Managed to find the old one so this is what it looks like after its been removed, you'll see how I ended up just cutting the pipes off as those clips are really difficult.
