Default Exhausts and heat

I've had the Quill T3 can on the Bandit 1200 for a couple of months now.
I'm fairly certain it's made a difference; the throttle response is
sharper, and there's definitely a kick as it passes ~5000 rpm. I have
noticed, though, that a lot more heat is being produced - my legs feel
much warmer. I'm aware that if the engine is making more power, then it
will give off more heat. What I don't know is whether this is a bad
thing or not; any advice?

If I'm being totally honest, I'll admit that the B12 doesn't need the
Quill; it's plenty fast enough for me with the standard can, and
although it sounds nicer through the T3, it's not bad at full chat with
the OEM unit in place; just a bit tame at tickover. I'm still not sure
whether to keep the T3 on it, in truth.

Leave the quill on so that should you ever sell there's a nice shiny new
endcan to put back on the bike, also if it gets dropped a quill isn't
expensive to replace compared to OEM.

My 10p's worth.

I assume the Quill is a hollow metal tube in comparison to the heavily
insulated OE can. The external part of the can is bound to get hotter. Not
a bad thing in the UK but tiresome if you go to Spain or similar.

Yes, but the heat I feel is being given off by the engine itself. It's
extremely noticeable, especially through denim jeans.

That would be the weak mixture due to the race can,
causing your engine to overheat.
Expect it to seize or hole a piston soon. :-)

Technically (and very very simply), if the engine is producing more power
from the same amount of fuel then if set up right it should be cooler as the
energy will turn the crank rather than warm the other bits of the bike.

To get warmer legs implies greater heat off the block which is probably just
your imagination or you being more aggressive due to the can...

The silencer will, however, probably feel hotter as you now have a plain
absorbtion(sp?) baffle so there's just a flow of very hot gases through a
tube...

Yes a B12 *does* need a new can/system! Its a mere 100bhp as standard and a
the can/system release loads more.... 20% more power *will_not* mean 20%
more speed so it'll still only be 'plenty fast enough', but it'll be much
more fun.. )

I can see you're in perplexment.

Give it to me and feel better.

I've got an ART can on mine, and it's certainly noisy, but I am a firm
believer that noise in the right place is a good thing.

In a colleagues car just a few days ago, heading into town, sitting in
traffic, wanting the next right hand turning. Driver started to indicate,
when I said, "hang on, I can hear a bike - can you see it?" (she's a bit
lacking in bike awareness), "no", came the repsonse, along with a
cancelled indicator. Sure enough a second or so later, A shiny MV Augusta
F4 trundled passed us. Not at speed, just filtering.

Anyhow, I digress, On the odd occassions that I ride tha bandit without
leathers, I really notice the engine warmth underneath the parts of my
legs directly above the engine. First time it was a little un-nerving, I
even checked my oil levels - then I realised it was the first time riding
in warm weather without leathers.

Leave the quill on, you've paid for it, it's worth diddly on fleabay and
it does help the bike exhale better. The extra oomph, is user defineable -
you don't have to yank the throttle, or twist it all the way round!

I know, it IS an alien concept. One I don't practice very often. I hear
it's likened to pretending the traffic around you matters, or, if there is
no traffic, pretending there is and that if it was it would matter.

or something. Wibble Flip....

I found the opposite on the SV when I had the Ti can fitted - it was cooler.

<moron mode>
Shouldn't this actually be the case as the standard can has a lot more
baffles in it to lower the noise.
That noise has to turn into something, I thought it would turn into heat.

It turns into millions of pretty butterflies flapping their gaily
coloured wings gently on the cooling summer breeze.

I'd have thought that the more baffles in it would effectively expose a
greater surface area of metal to the hot gases - so more heat will get
into the casing, rather than being ejected directly.

The baffles just alter the frequency of the sound, IIRC, which makes it
sound a bit quieter (what I'm referring to here is the combination of
frequency and amplitude that makes something seem louder - referred to as
phon - a high pitched squeal will sound louder than a low pitched rumble
at the same volume.)

<unscientific guesswork mode>
But the standard can would have lots more metal and tubing inside for the
heat to be conducted through, whereas with a straight through can the gases
just have a little bit of wadding between them and the outer skin
</ugw>

Who knows?

Well I'm sure someone must know so maybe I'll leave it up to them to answer
the question definitively.

What *was* the question again, anyway?

It's almost, but not quite, that simple. The Quill T3 (marked only with
BSAU193A-T3/1990) has a baffle of sorts, which (according to the blurb)
seems to have some sort of pressure-reactive valve thingy in it; under
~5000 revs it acts as a moderately baffled street can and above that it
acts as a straight through.
