Digital speedo's

Analog gauges give you easy to extrapolate rate-of-change
information. If you want to watch the clock as you're
accelerating, and predict the time at which you hit 100,
you'll be more accurate than if you try to do this from
a digital speedo.

For maintaining an arbitrary constant speed +-1km/h,
digital is better IMHO.

A few paragraphs above you typed the number 105. How many seconds did you
stare at the number which I typed at the end of the last sentence before you
realised it said one hundred and five? There are 26 letters alphabet vs 10
digits in the decimal system. So would a 3 letter word like "THE" take you
2.6 times longer to interpret than a 3 digit number? By my estimates by the
time you get to the end of this sentence it will be well past your bedtime

No wonder you can't ride at a steady 60km/h....

He means his boyfriend's Speedos.

 

Notwithstanding that I'm big on analog speedos for
overall readability, I think a well calibrated digital
speedo is probably quite critical for one who wishes
to make sure that he's not paying more than his fair
share of tax, 'specially given that reduction to
3% tolerance in some bits of this island.

I could dissect that, point by point, and come up with
some sort of half ahsed argument. But I cahnt be ahsed.
Shall I just go and hand in my license now?

Wait, no, I think I'll just call you a troll. That way,
I'm absolved of all requirement to answer logically, 'cos
you're a troll. And while I'm at it, you should be ashamed
of yourself for not trying to sell that bike that wasn't
even yours that you didn't thrash, Nev!

I had a digital speedo on a Fairlane, and didn't like it. I have one on the
SV650, and I would prefer to have an analogue dial.

The digital thing can only show one speed at a time, but a dial shows the
rate of increase/decrease in velocity as well as the actual speed.

 

Geez - when I'm accelerating that hard I need to "catch" a speed I just
listen to the engine and hang on for dear life. Rev limiter in first gear
is about 105km/h anything under that goes something like this: "BRAAAAP!!,
clutch, click, click, click, (4th gear) release clutch, burble, burble...."
then adjust the last coupla km/h from where ever I ended up (usually about
80km/h). Oh, then check the mirror for any flashing lights

Terrible things, so inaccurate[1].

[1]Bet you googled too....

 

No, he is just a wanker.

Rev limiter doesn't threaten to chuck you over the
bars at 106Km/h in first? My bike doesn't have a rev
limiter. Car does. Wouldn't like to hit *that* rev
limiter on a bike - it's brutal.

Bob

 

The rev limiter cuts in at about 135-140kph on the 12R. Not violent at all.
What does yours do in the car? Apply a brake to the crank?

Dunno exactly. Allegedly only supplies fuel (fires
the injectors) on every second (8th?) stroke until
it gets back below the redline, but don't quote me
on that. Doesn't sound particularly spectacular on
paper, but it's quite brutal in effect.

(It's a Nissan SR20DE (1994cc, twin cam, efi) in
an N14 Pulsar. Same engine they put in the 200SX,
but without the turbocharger)

Bob

 

I have a Nov '91 Pulsar N14 SSS, and the rev-limiter isn't what you would
call brutal in mine.
In effect, it feels like valve-bounce in a pushrod engine did, that "no
point in trying any harder" feel.
A brutally-abrupt rev-limiter would be a bit of a worry.

Conehead

 

Mine is a September '92 SSS, but it's the same engine,
same Australian built car. The only thing non-standard
about mine is the 15in wheels, so unless you've changed
yours too, yours is prolly faster off the lights than
mine. (Which is still not very bloody fast!!!)[1]

Mine is very much "WhatTheHellDoYouThinkYou'reDoing,
YouCanFuckRightOffIfYouThinkYou'reGonnaDoThatToMe"
kinda rev limiting.

My 'brutal' is probably a *bit* of an exagerration, but
there's absolutely no doubt that it wants you the hell
off the 'go' pedal. It is quite abrupt.


In other (very off topic) news, you may be interested to
learn that we put a new clutch in mine about a month ago,
and managed to do it *without* taking the engine out.
Undo the mounts on the gearbox side, but not the engine
side. Put a jack under the engine, pull the member that
goes front-to-back under the middle of the engine out,
then lower the jack enough to pop the gearbox off and on.
Went quite nicely in fact.


(Actually, I lie. I've got a mate who's a gynacologist,
he did the whole job through the dipstick hole)


Bob

[1] Not terribly sluggish either. I went through the routine
of being the "Mate who knows about cars" for someone who
was buying a new-ish small sedan recently. Compared to
some of the truly shocking crud out there, the ol'
Pulsar isn't too shabby at all. He ended up with a strange
little 92Kw (Pulsar is 104Kw) Scooby Doo Impreza, and it
was interesting. AWD and all, it was still quite
significantly easy (scarily so) to lose the butt in it.

 

Actually no, I take that back. 50 profile tyres. Same
rolling diameter. No difference. Forget I spoke.

Bob

 

Actually it's pretty gentle. I think it simply cuts the ignition on every
n-th stroke. The bike pulls really hard up to about 11k RPM then you can
feel it running outta breath so when 12k + some RPM causes the rev limiter
to kick in, the machine is pretty much finished accelerating. It more like
the bike is saying "Err, dick head - another gear please....when you're
ready" - it's not harsh (for the rider).

Although if the front wheel is in the air when the rev limiter kicks in, it
can get ugly. Saw a guy on a YZF-1000 do it and it ended in tears. He hit
the rev limiter, front wheel started coming down REAL quick, rider paniced
and went "clutchless" into 2nd with wide open throttle. Bike almost
immediately somersaults but rider had enough sense to let go. Rider was
bruised and sore. Bike was totalled (insurance right-off), mainly coz it
ended up sliding into a big-arse tree.

As the owner or two bikes with analog instruments and one bike with a digital speedo and analog tacho - the DIGITAL
SPEEDO SUCKS................................. BIG TIME!!!

Sorry, but I don't know how to put it any clearer than that!

I imagine it's great for the track where you don't give a S**T what it says but on the road it's a total loose.
The analog instruments can be watched from the corner of the eye. The needle position and angular velocity accuratly
conveys the information without the need to look or concentrate of process the meaning of a couple of digits, wheras
the digital speedo requires constant attention.

I find that if I blast off the lights and roll off the throttle when the speedo is reading 50kph, by the time the damn
thing stabilises I'm actually going fast enough in a 60 zone to blow half a license between christmas and new year.
Not to mention the fact than it's damn impossible to read at the wrong time of day.

As the owner of one, I HATE digital speedos (and that's putting it politely).

Cheers,
Kath

aus.moto PP006 - desperately in need of a reprint! Where's CrazyCam?

 

No modern mass-production 2-litre has made mine look sluggish, even with my
not-insignificant mass in it, and that includes the local Pulsar hotshots in
their heavily-modded things.

I think the initial offerings might have had a fair tweak at the factory to
get the journos and trade on heat. Mine is a very early one.
