Right, my bike and the area around my bike smells of petrol and everyone is saying thats not right theres something wrong with it. Well every bike ive used has had that typical bike/petrol smell so im assuming its nothing out of the ordinary as theres no leaks or puddles under the bike so why does the bike smell of petrol? Smile

*told you it was retarded*

could just be excess unbunt fuel in the exhaust gases. does the smell increase when you run the bike?

Well first thing I'd do is put a "No Smoking" sign on it, for whenever you go out on it. Then go around it checking for slight leaks, mainly around the petrol tank and carbs. If you can't find anything then stick pine tree car smellies around your friends necks to shut them up.

It's probably just fumes from your vented fuel cap .

Do you leave the fuel tap on when the bike is sitting around? It's possible that the float valve could be allowing some petrol to escape from the carb overflow pipe.

Just a quick word of caution that yes it may well be the tank vent as air needs to be let in to allow the fuel to flow out.... but petrol vapour is heavier than air so it goes down, not up. Whilst it may smell a bit around the vent it's not usually enough to be intrusive.

A quick and easy way to see vapour is to place your bike in the garage. Put a light coloured board or sheet in the background and shine a light towards the bike. Now watch the shadow closely as vapour is immediately obvious. Watch 'under' the bike to see it falling. You might need to do the bike on both sides. If you don't see any vapour then the amounts leaking are nothing to worry about.

Try the trick with some petrol in a jug first (if you don't believe me Laughing ). Tip the jug over just enough so that the petrol can't flow out. In the shadow though the vapour will be 'pouring' from the lip Thumbs Up

When was the last time you filled up?

Could you have over filled?

I have done that and the garage reeked of fuel.

Your garage smells of petrol? You're lucky, mine stinks of god knows how many solvents, greases, degreasers, paints, lacquers, varnishes, oil and also petrol. It's enough to make you feel odd sometimes. Confused

The last time I got a really bad petrol smell it was because I was moving a tank and somehow managed to turn the tap while I was putting it down on the bench. Shocked

There's always a bit left in the hose at the pump to annoy you too. Rolling Eyes

My bike used to smell a lot of petrol, but not so much these days. No idea why.

I assume your bike is carbed? If so, and if no liquid petrol is leaking out, I wouldn't worry about it too much.

waft a light match around the parts of the bike that might be a cause, eventually you will not only find the problem but cure it at the same time,















my bike pongs from the air ducts, after a buzz

Agree. Turning the petrol off is standard practice. Many modern bikes have a vacuum system that does this for you now. If you have one of these, it could be faulty.

Which bike is it?

Guys if you are still experiencing gas (fuel) smell I found the solution to it on my Yamaha XT660Z Tenere 2009. It got very bad about 3 weeks ago so I removed all bolts from fuel cap and found 4 small springs under the rubber seal. Make sure you put rag over the fuel tank neck so you don't drop anything inside before you start removing anything. I extended those 4 springs by about 5mm by pressing flat head screw driver in between the spirals of the springs. Put them back in and it solved it all. No more gas smell. Those springs get weaker with age and there is not enough pressure for the rubber seal to seal the fuel tank entry. Good luck with this and don't inhale fuel vapour if you don't have to. Smile Stay safe.


Thanks for that (and resu-rectuming a thread from Tutankhamun's Forum.)
