No, I didn't wet myself...

[Spinal]

Just a short funny... this morning, I decided to ride the bike in to work...

I filled up on my way to work... and obviously forgot to close the fuel cap properly...

On my way home, taking advantage of the sun, I decided to ride a bit more... enthusiatically... In response, the fuel cap leaked a bit fo fuel every time the angle was right...

So by the time I got home, my jeans were quite wet and other than the strong smell of petrol, it looked quite a bit like I wet myself...

Ah... motorbikes You gotta love them

[whitenemesis]

Yes, of course.. I beleive you Spinal

 

[Dieselman]

other than the thong smelling of petrol, it looked quite a bit like I wet myself...

Good biking wear are they spinal.?

 

[greggster]

simialr thing happened to me years ago in the days when i used to drive around with a mug of tea between my legs on the way to work. I got shunted from behind in traffic, got out to check the rear bumper and the woman who hit me was amazingly nice to me and kept asking if i was alright, did i want to have a sit down etc. I later noticed the wet patch on my crotch from the spilt tea

mmmm. we recon you were drinking petrol ...

 

[Frank O' Phile]

You make no mention of the effects on the area by the cold as the petrol evaporates.

I took the FJ12 out yesterday around Derbyshire and Lincolnshire, dressed much the same as I was for the lovely warm afternoon we had on Wednesday...... and it was bl00dy freezing.

Good thing you don't smoke I guess..

Excerpt from this........

What happens when gasoline comes into contact with my skin?

When gasoline is NOT trapped against the skin and can freely evaporate, it is probably only mildly irritating or not irritating. However, case reports indicate that when gasoline is trapped against the skin (clothing is soaked in gasoline, skin is in contact with a puddle) for a long period (probably more than 30 minutes), serious burns and skin loss may occur. Absorption through the skin occurs, but is normally not significant.


So be warned.....................

Thong!!!!!!

I thought we sang thongs

 

[Spinal]

I must admit it was cold - but not that bad... the cap was only ajar, so the fuel was trickling...

Also, it wasn't that long... roughly a 10 minute ride... and I had a V2 keeping me warm (which was my real concern...) does anyone know what the flashpoint of 97RON fuel is?

Aren't they the ones that make that really ugly Rodius thing?

So you'll be wanting the fold-out cup holder for your 211 that goes in the cubby just behind the gear lever, then - problem solved!

Actual petrol is virtually incombustable. In theory, you could plunge a lighted match into petrol and it would extinguish (BUT PLEASE DONT TRY IT).
Its the vapours that ignite - when combined with air (oxygen) that it becomes combustable.
The normal flashpoint of petrol is about -40degC.
Diesel is about +60degC.

I can assure you that there were LOTS of fumes... I could smell it from indide my helmet...

Though I really do want to try the match in petrol idea If I were to pour petrol over a match, in theory the liquid should hit it instead of the fumes (if poured fast enough) right?

As for the flashpoint... I think I got my terminology wrong I meant the... uhm... spontaneous-combustion temperature... (as in, if I drop petrol onto the hot engine, what temperature does the engine need to be to ignite the fuel and burn me to a crisp?)

It won't. You need a spark or flame to ignite petrol.

It won't. You need a spark or flame to ignite petrol.

The auto ignition ( or spontaneous combustion) point of ordinary petrol is between about 240 to 250 degC (car diesel is a tad lower at between 150 to 200 degC).
Car engine blocks dont normally get hot enough to pre-ignite petrol, so dropping neat petrol onto a hot engine shouldnt normally ignite it. Although, as I have said before I wouldnt try it.
Exhaust manifolds can and do get get hot enough to do this, which is basically what the bang you hear from an engine "backfire" is. Its the unspent petrol from the engine igniting in the upper exhaust manifold.

Tell that to my old lawn mower..... it did a good job of igniting itself when it was being topped up with petrol........

Was it running at the time.?

Years ago Top Gear ran an issue about car fires after accidents.
They demonstrated petrol being squirted onto a hot exhaust manifold and all it did was evaporate.
They then performed the same test with brake fluid, which ignited.

The point was that many manufacturers don't have a proper retainer for the brake fluid reservoir and they can come off in accident situations.

I saw a Fiat Punto at the side of the motorway yesterday, there were flames coming from the engine compartment but I was surprised to see a 'clump' of something on the floor under the engine which was firmly on fire.

It looked like a solidified mass of some kind, rather like the drippings off a massive candle had landed there.

Plastic?

When I was a kid back in the 1960's my father worked on the bench as a motor fitter (the fancy name "Technician" came much later ) and I would accompany him to the workshop when he did any work on our car on a Sunday morning. Anyway, back in those days it was commonplace for each fitter to have a large tin can on the bench (about the size of a 2.5 litre paint tin) part filled with petrol that they would use to wash off parts. A sort of primitive degreasing tank if you will. I was amazed to learn that it was nothing unusual if something small caught fire to drop it in the petrol tin to put it out

Petrol vapour is, as you say, a completely different kettle of poisson...
