Pissed Gas smell after canister and SAS removal

I went for my first long ride after the removal of all the junk. I smelled gas when I got home so I checked the breather hoses - I had run them down past the top of the skid in front on both sides. Both hoses had liquid coming out them - smelled like gas but was kinda oily in consistency. Is this normal? Do I have a venting problem? There was only about a 1/4 of a tank of fuel and it was not hot out today.

thanks

Which breather hoses? Gas tank? Would seem strange that they would be leaking gas at this time of year as you noted.

How'd the bike run on the ride? How much liquid is coming out of the hoses?

I suspect it is simply remaining residue from when they were piped to the canister. That is unless you cleaned them out. But you certainly could get enough vapors from the fuel to condensate out inside the vent hoses. With this mod you will from time to time get a gas smell simply because of the lack of the canister.

They were the tank breathers from the fittings on the front of the tanks.

There were only a few drops from each hose. She ran fine - like a scalded cat

No, I did not clean them out after recycling them from the canister removal. I did think of that so I will hope that that is it. Going to do the cap vent mod too just to be on the safe side.

One of my local good wrenches on the 950 (he has an "S" himself) mentions that it is important to have the hoses off the front tank vents "loop" above the level of fuel which will ever be in the tanks, or you will get some dripping. He did something (which, unfortunately, I did not inspect) to his bike where he brought both vent hoses up, out and too a Tee fitting, then used a single line from the tee as a drain.

I recently looped my vent hoses up individually, using loose zip-ties to keep them in place, and have noticed less fuel odors. I didn't have the OEM vent lines, so I had just bought some clear tubing from a hardware store. You could see at the end of each hose some road grime which was sticking to fuel which was exiting the vent lines. Made the hoses black at their ends for about 1.5 inches. So I may have been dripping a little (condensed vapor?) gas originally, but now I don't seem to be any more.

Sometimes after refueling a gas cap doesn't latch and I get a fuel smell. I've never noticed anything from my fuel vents, though. Well, maybe once when I dropped it with full tanks.

Looks like you found out why there was a canister on it in the first place.
Maybe thats why they run like shite when it gets all shook up or goes into rest mode.

Even with the canisterectomy, the tanks may not vent properly until the caps are modified. See this link for more info on that:



Also, many folks assume that the elbows at the front of the tanks are holes directly into the tanks. They are not. They are plumbed back to the caps. From there the vapors must travel though a maze of very tiny passages to get to the inside of the fuel tanks. These tiny passages are easily blocked with liquid fuel, the effect of which closely replicates a pinched vent line or clogged canister.

Yup. Saw your post on that earlier and did the mod yesterday. Only takes 10 mins or so.

Damn, guess I forgot to put my copyright label on my photo sheet. At least it is being put to good use.

How did you ever come up with the idea to look at the fuel tank cap to do this mod???
