Fuel smell

Postby sjrainsford » Tue Mar 13, 2018 11:03 am

Hi all!

I keep my R1100S in my garage which is attached to the house. There's a cat flap from the kitchen into the garage. I've noticed that the bike smells of fuel quite a lot after use, and more so when the tank is more full. It can last for days. The problem being, this smell navigates it's way into the house.
As you are all aware it's Mick's old bike with only 15k on the clock. Are there any common failure points, or does the ventilation need modification? Just hate the way the smell lingers. My vespa will smell after use for a couple of hours, but won't if I leave it out for a few hours before bringing it into the garage. Plus my old suzuki was the same. Whilst leaving it outside for a while helps with the R1100S, it doesn't completely get rid of the smell. I'm guessing they don't have a carbon canister as required on newer bikes.

Spray powder deodorant and then fill the tank..may reveal exit point of the fluid. Could be large O ring on access to fuel pump??

I would check that the breather hoses are free and not blocked.

I dont know / cant put in to words how this may help so maybe I am barking up the wrong tree.
Cant hurt though

I bought my 11s years ago with similar mileage and discovered that the o ring that seals the petrol filler cap assy was leaking . When I eventually removed it I noticed that the o ring had been pinched incorrectly on assembly .
See if you can locate where the vapour is coming from, whether from the breather pipe ( exits near the swing arm on the R/h side) or somewhere else higher up .( might involve crawling around on your hands and knees..)

If fuel vapours can exit... then moisture can enter, do not go out in the rain. Check the main filler cap 0 ring seal on to the fuel tank.

jus sayin!

I've found the source of the smell, and to be honest I'm a bit of a numpty! :oops:

It was just the filler cap that wasn't shut properly. I've never done that before. Never noticed till I'd got the side panels off to investigate. :roll:
Still, it gave me chance to tape up a few more cables that are cracking. Need to remove the tank and do a proper job of it really. They're rubbish in my opinion!

And I'm actually an engineer! :lol:

I think the youngest 1100S will be 14 years old now, the covering around the wires wont last for ever.
I recovered ALL my 1150GS wiring in 2012, 10 years old at the time as most of it had broken up - but I live in teh tropics and most rubber products dont last in this environment

There would appear to be a surfeit of prolixity and sesquipedalian content today please do not use a big word when a singularly un-loquacious and diminutive linguistic expression will satisfactorily accomplish the contemporary necessity
