There is now an iPhone app to check your tachometer. It is called "Engine RPM"
and it is in the Utilities category in the App Store. It uses the sound of the
engine to determine RPM as accurately as an optical tach. It works on any
engine that makes noise: small planes, motorcycles, R/C models, etc.

This app is based on our "RPM from Sound" freeware Pocket PC app that has been
available for years. But this iPhone app is more reliable, easier to operate,
and covers the range 500 to 90,000 RPM.

usually I would say fuck off spammer bitch...but this kinda sounds
interesting

does it would on and iPod touch?

and anyone else, do apps designed for the iPhone work on the iPod
touch? I have no need for an iPhone cos I have to have a Crackberry
for work, but I am hearing pretty good things about the Touch and at
1/3 the price.

$11.99, no reviews and no trial version. Good fucking luck with that,
Robert Scott. Reduce the price to $0.99.

Hehe
Check out their *other* app, a piano tuner.

No wait - I'll save you the trouble. It's $350.

Straight up. Not $3.50, three hundred and fifty dollars.

(well - less one cent)

Still think $12 is steep?
A plastic cable clip for my Bonnie cost me that much.

Sure is. I think the most expensive app I have spent money on cost me
$8.99, but that one actually saves me money every time I use it.

All things are relative.
$12 is a lot compared to $0.00, but not much compared to $350.

BTW - tach app is pretty much meh.
Only digital display, and takes some fiddling to get it to settle down on
the Bonnie.

Definitely not to be relied on.
Interesting, though, and actually pretty clever.

The iPod touch can access the app store as long as you are in a wifi
area and it will run all of the apps that the iPhone 3G will run that
don't require mobile phone access.

There are some apps that require the GPS/compass hardware that is only
in the newer iPhone 3GS (eg the Tom Tom GPS software).

But the iPod touch will run the vast majority of apps from the app store.

Yes indeed, compared to the majority of the iphone apps, $12 is VERY
expensive.

internal hardware).

A silly question, perhaps, but why?

The tachos on most modern bikes are digital and ought be at least as
accurate. Would any slight error make any real difference?.

I wonder if anyone makes this software for PC? I have a few spare

I have to do some fine tuning on the CB, and its the kinda thing where
you have to turn screw "a" and see if the rev rise or fall by 50rpm...
so a accurate tacho is a must

I am a novice at carbies, so guessing inst really an option ATM

Just about every motor vehicle I've ever owned has come with a
tachometer factory fitted. I find it hard to believe an iphone
tachometer could be used as anything other than a gimick for a vast
majority of the population. If you need one then maybe it is value for
you, but I struggle to think of any circumstance when a tachometer app
would be of actual non-novelty use.

If it is accurate enough, for engine tuning you can not see the the dash
tacho from the engine.

Last time I looked, the local bike shop wanted something like $250 for a
tacho for my Bonnie. About half that if I import a third party one from the
US, and invalidate the warranty installing it.

$12 is nothing.

you have never worked on, restored or rebuilt a bike/engine/carby
then?
ever built and played with RC aircraft?


you are, like some others in this thread are thinking a Tacho is only
use to change gears

people who work with engines would find this app quite useful for
tuning

ebay is full of optical/laser tachos
http://shop.ebay.com.au/?_from=R40&_trksid=m38&_nkw=Digital+Tachometer
just because you wouldn't use one, and all the Vehicles you have had a
standard Tacho, then no one need these either?

I could go on for hours about the test equipment that I use that
almost all people in the NG would go huh? and guess what, the prices
are expensive, welcome to the world of test equipment, its pricey.

My daily test equipment is valued at around $30k and thats so people
can surf p0rN and make phone calls, I hate to think of the value of
the some of the stuff in the Exchange.

but I wouldnt use a iphone for testing would I? I dont own a iPhone,
but I use my crackberry to control a wireless ADSL modem that is
networked (and gaffer taped) to a SHDSL modem for testing purposes,
its great for the simple faults like authentication and sync issues..

back to motorcyles

here is the procedure to adjust the pilot screws on a NT650 (the
quickest I could find on the net, same as most I have seen)

1. Turn each pilot screw clockwise until it seats lightly and back
it out to the specification given.
This is an initial setting prior to the final pilot screw
adjustment.

INITIAL OPENING:
49 St. model California model
'88 2-1/8 turns out 2-1/2 turns out
After
'88 Front: 1-1/2 turns out
Rear: 1 turns out 1-3/8 turns out
CAUTION
* Damage to the pilot screw seat will occur if the pilot
screw is tightened against the seat.

2. Warm up the engine to operating temperature.
Stop and go riding for 10 minutes is sufficient.
3. Attach a tachometer according to the manufacturer's
instructions.
4. Adjust the idle speed with the throttle stop screw.
5. Turn each pilot screw 1/2 turn out from the initial setting.
6. If the engine speed increases by 50 rpm or more, turn each pilot
screw out by an additional 1/2 turn until engine speed drops by 50 rpm
or less.
7. Adjust the idle speed with the throttle stop screw.
8. Turn the rear cylinder carburetor pilot screw in until the
engine speed drops 50 rpm.
9. Turn the rear cylinder carburetor pilot screw 1 turn out from
the position obtained in step 8.
10. Adjust the idle speed with the throttle stop screw.
11. Perform steps 8, 9 and 10 for the front cylinder carburetor
pilot screw.
12. Drive new pilot screw plugs into the pilot screw bores with a 7
mm valve guide driver (P/N 07942 - 8230000). When fully seated the
plug surfaces will be recessed 1 mm.

No, and neither do the vast majority of the population. The ones who
do, have a tachometer. What? You don't have a tachometer? What kind
of bike/engine/carby restorer/rebuilder are you?

No, and neither do an even more vast majority of the population.

Why would you need a tacho to change gears? Back off the throttle, pull
in the clutch, give the gear lever a kick... nope, no tacho ;)

So the worldwide production of Tachometers must stop now because all
the people that will ever need one, replace one etc has dried up?

I think the argument that the neither do the vast majority of the
population is a little mute, if things always needed the vast
majority, very little would ever see final production. All that is
need is a market.

No, you need to reread what I have written above, because I don't
think I said what you think I said. I never said that noone would
need a tacho. I'm sure there are thousands of people every day who
have the need to buy such a piece of equipment. But the majority of
them will buy a quality instrument. By quality I mean an instrument
which actually measures the engine speed, rather than an iphone app
which guesses it based on audible cues (which may or may not originate
from the engine who's speed is being measured), and even invites the
user to contribute their own guesses so that it can guess the engine
speed more accurately. I would call that a novelty. I say that
relative to other iphone apps, and especially novelty apps, $12 is too
expensive. If it was .99c I would buy it in a flash and measure the
engine speed of everything I could, but not because it was a useful
pursuit...

and I suspect 116,605 of them have motorcycles which are already
equipped with a tachometer which is far more accurate and reliable
than any iphone app. Why would they need another one?

The folk who didn't buy I_Am_Rich, either because they couldn't afford
it, or missed the brief window of opportunity, might well buy a
tachometer app instead.

Surely 'dropping 50 revs' is an aural indication. They don't mean
"exactly 50 revs or between 49 and 51 revs". You don't need a tacho
for that. I think most dwell meters have tacho capability, but
analogue tacho's won't indcate a 50 rev change with the accuracy you
appear to be asking for. You are just looking for a rise or fall in
revs, not a specific number of rev change.

You don't need a tacho for what you're trying to do.

I would not need a tacho to do the above Marty. This is a standard
carb tuning procedure, unchanged since before Johnno was born.

That's a bit mean. Shoving someone up the end of a trumpet because
they can't speak.

Only time I really needed a tacho to make a vehicle run just right was an
outboard ski boat. Makes a fair difference in speed and fuel when you have
the trim just right. A hundred rpm or so makes a few knots, over hours it
can add up.

For tuning I find a pair of mercury tubes quite useful, and much more
sensitive to minor adjustments.

Good, you we be on the next plane over ;-)

I know there is lots of things that you can do by ear, but sometimes,
especially when learning that it is nice to know you are doing it
right.

Not currently. That is only because I did not think that Touches with
microphones were that common. Apparently I was wrong. So in the next update we
will be enabling the iPod Touch 2nd generation or later with a microphone. And
sorry for violating the posting standards of this group with a commercial
announcement.

Not much here. Decided to take them to my sister's where it won't be
flooded during the wet. Will do the job there.

Suzuki leaking oil, eats brake pads, choke is stuck, heat shield on
exhaust fell off. 13,000kms.

You know if you were really sorry you would cancel your posting... and
where's the apology for the expensive pricetag ? how about an itunes
vouchers so I can evaluate the software and report on it to the rest of
the group.

Silly question, but why ? Why not install a permanent gauge if you bike
doesn't have one ?
