OK, guys, I had to go to a book that is almost too heavy for me to
lift, and it cost us $240.00, but I finally found what we were
looking for.

The flash point for gasoline is -50 degrees F (-45 degrees C).

The autoignition temperature varies by octane, and I'm assuming
these are Research octane numbers, although the latter two look
like they may be for aviation fuel.

 50-100 octane:  536-853 degrees F.
100-130 octane:  824 degrees F.
115-145 octane:  880 degrees F.

The upper limit of combustion is 95-100 percent.
The range of explosion is from 1.2 to 7.1 percent.

It looks as if the temp of an air cooled engine, particularly the
exaust pipes near the head can reach this temperature.  The surface
of the engine may never get this hot, and the evaporative cooling
of the fuel may keep it well below these temperatures.  On the
other hand, any catalytic affect of the metal surface and the
presence of other substances  may push this temperature a lot
lower.

I think that while it is possible for auto ignition to occur, it is
rare for all the conditions to be met to start and maintain the
combustion.  I've certainly spilled my share of fuel on hot
engines, even exaust manifolds, with no problems, but I have heard
of people who haven't been so lucky.

There is a device made call a pre-luber (I think...). It was developed primarily to 
supply oil to turbo chargers after the engine was shut off.  As you may know,
the turbine in a turbocharger may spin for up to a couple of minutes after the engine
is switched off.  This can cause the oil in the bearing (sleeve type) to Coke up
due to the heat or just run dry causing damage to the shaft and or bearings.

The device is a cylinder with a floating piston.  There is an inlet on one side for
pressurized oil to enter (connected to the oil inlet of the turbo) and air sealed on
the other side.  When the engine is started, oil flows into the device until the 
pressure of the oil equalizes the pressure on the other side of the piston (air side).
If the oil pressure suddenly drops (as with when the engine is switched off) the oil
flows back out to the turbo.  A check valve prevents it from going back to the engine.
This will maintain enogh oil pressure to the turbo to keep it happy until the turbine
stops spinning.

This same device is used (differently) to prelube an engine.  This time it is connected
to the oil mains in the engine through a solenoid valve.  When the engine ignition is 
on the valve opens and oil fills the cylinder.  When you shut the engine off, the 
valve closes trapping oil under pressure in the device.  When you go to start the
car, the valve opens again and oil under pressure is forced into the engine.  And so
on and so on...

These devices are sold by racing engine companies and turbo charger companies.  Sorry
I don't have any sources.  Hopefully this is somewhat useful.

Yes. PeltierEffect.  Same principle as a thermocouple, but runs in reverse.
I sent for some info on the chips that do the work, by Melcor in the states,
and the stuff is really cool.8)  The problem is power: it is very inefficient
at moving heat.  And the "hot" side of the chip gets all of the resistive heat
from the chip, as well as the heat drawn off from the "cold" side.  I think
that they had a 2" square chip, one side of which was inside the helmet, the 
other side was bonded to a heat sink that stuck out of the top of the helmet.
No one seems to be worried about a 2" square hole in the helmet for safety
reasons, but I don't like the idea.

Now, making a Peltier effect kidnet belt might be nice...  The heat sinks would
be flat aluminum plates on the outside of the leather, the cold side of the 
chip would be bonded to fine copper mesh that was right under the inner layer
of leather, inside the padding.  That might have a greater effect on perceived
temperature.  The current could be reversed, making it a heater in the cold..

 That's not the same thing.  The muff device is a *limiter* - it just

 Active suppression works by introducing an antiwave to the ambient

to minimize *perceived* sound.

Hi y'all,

So my bike has been sitting for about a week and a half.
It's a 1980 CB750F.  I covered it to keep the rain and snow
off of it. (yeah right, that worked...) I go to start it up, and
the starter spins... and , nothing else.  I pull the plugs,
they're wet with gas.  Guess I was a little excessive with the 
throttle.  I end up jumping my bike with my car. (oh no, not 
another "Can I jump start my bike without turning it into 
a pool of metal" discussion...) It turns over much faster, but still
no coughs of sputters or anything!

Sigh.  I cleaned my plugs and waited.  Still nothing.  
A mechanic I know is telling me that I "fouled the plugs
and have to replace them."  But thet're less than a month
old!  Hmmm.  I'm about to try some starter fluid...

Ojh, and yes, I do get spark, and I assume it's at
the right place and time because it was running very nicely
when I parked it.  Maybe water in the gas from rain and snow?
I'm guessing here... It seems that I have discovered the 
infamous CB750 hard-atarting phenomenon.  Any CB riders out there
with sage words of advice?  It's sunny and in the 40's.  I can ride
in this weather!

That was the same incident, I did the slapp dance until I went off

time too.  Had to wait 45 minutes for the next vehicle to come
along and then we had to pull the Battlestar upright before dragging

Sounds pretty dumb to me.  David, do you understand the concept of 
insurance?  The point of insurance is to spread the cost of accidents 
over a larger base of people, so no one person is crippled financially 
should an accident befall them.  If you make people "pay as they go"
instead of allowing them to spread the risk around through
insurance, why not just outlaw insurance,  and make everyone
pay full cost for their accidents?

Perhaps even more to the point, why don't you just take the
absolute minimum insurance allowed by your state, and take
your chances in the courts if you have a major accident?

Sounds like harrassment to me.  What's the point of allowing someone
to do something, and then making it so hard to do it that they
choose not to?

I just bought some old (old item, new stock: inventory time!!) Hot Grips
for my 'Wing.  They're still made by he same people, and you might try 
snowmobile shops/catalogs.  They were in the last Dennis Kirk catalog I had
(or maybe it was Chapparal?).  They are universal, and it seems they want you
to EPOXY the grips to the bars!!  Anyone have any better ideas?  Contact
cement, maybe?   Epoxy sounds really permanent.  I'd almost rather
bolt them on somehow.

There was a modern version that was neoprene heated covers for grips, velcroed
on over your current =:) grips and plugged into the electrics so you could
take them off when it's warm and don't want to have big, lumpy grips.  These
were more expensive than the $16 I paid for mine, but might be a little nicer
