Speedo inaccuracy?

Discussion in 'Australian Motorcycles' started by James C, Nov 13, 2008.

  1. Careful, you're painting with a very big brush. I've been through four
    bikes, (all different flavours of yamaharleys, plus one Kawasaki of a similar
    theme), non have been closer than 5Km/h at any useful speed (above 40), and at
    least one of those edging close to 10Km/h off towards the windy part of the scale.

    And as per usual, none of them read slower than actual.

  2. Is it worth your time away from work, plus fine, plus court costs to piss
    them off like that?

    The average cop would just be pissed off doing more paperwork than usual, the
    average punter I'm guessing would be MORE pissed off due to loss of wages,
    fine and costs...

    Nice idea if it were viable, but I don't see it happening unfortunately.

    You'll only confuse the discussion by throwing in odometer variance.
    The ADR allows for a much smaller odometer variance than speedometer.
    Off the top of my head 2% is the maximum allowable variance for an odometer.

    Do you really think they would roster all of those cases to be dealt
    with on one day, or would the same court:road ratio for police apply,
    and the backlog/waiting list increase. The only benefit I can see is
    that due to delays there would be a greater number of cases where the
    witness had left the job, or might be on sick leave or holidays and
    unable to attend to give evidence, or in extreme cases, the applicable
    limitation might expire before the case could be heard.

  5. Pfft! You'd think a Linux Registered User would have been around the
    traps long enough to read the whole post, not just the first sentence.
    My assertion was that no motorcycle speedo underestimates the speed
    (which was the example Iain was using). You seem to be asserting exactly
    the same thing.

  6. Sorry, I've been missing lots of things lately.

    And as if it didn't need any, there's more 'confirmation' that every car I've
    been in (with a gps at the same time) also does the same thing.

    Except for the Holden Commodore (any later model flavour anyway). They're
    close enough to spot on that you'd have trouble telling how far off they are.

    Australians can get things right after all...

    My VZ commodore speedo was about 0.5% - 1% out but the speedo on the VE
    is more like 4-5% out. Don't know whether the wheel sizes make much
    difference between variants.. the VZ had 17" wheels while the VE has 18"

  8. Size of the wheel shouldn't be a concern or any difference, as the outer
    diameter is the same
    The tyre joint will fit tyres to suit, if you take your 16" off and replace
    them with 19" or whatever, they will calculate which size tyre is more
    suitable so that the outer diameter stayes the same

  9. :) All bets are off in that case. It's too hard to guess if the wheel
    circumference is the same as the original factory set.

    If it isn't, then it's up to the owner to take care of corrections to fix
    that situation. Even if it's impossible (which it usually is). They're just
    making it harder to do anything.

    Notice how you could pick any commodore in the '70s and mix and match any
    bits any way you like? Notice how you can pick any modern commodore and have
    to spend a stupid amount of time to find ANYTHING other than bog factory
    standard that physically fits without using a hammer?

    I'll take that back about the Australians. At least some of the imports are
    flexible in that manner.

    Those are the original factory wheels.

    That was the Cali, it was spot on at 110, as measured between 10km
    pegs on highway 1. The odometer was 9%slow. I didn't know I'd been
    flashed till two months later so have no idea what my indicated speed
    was, probably 108. The bit that hurt is that that speed on a similar
    road in WA or SA is quite legal, and therefore allegedly safe as
    houses.

    Obviously Veglia odometers have excemption status. I've never had an
    odometer that close.

    <boggle> Well yes, given there was only one model of Commodore
    released in the 70's (1979MY - VB - the first model) then yes it's
    very easy to mix and match - if they weren't compatible there's a
    bloody big problem !!

    Were you thinking of H series Holdens perhaps ? If so then yes there
    was a degree of compatibility but you couldn't just willy-nilly take
    bits of say a HR and bolt them onto a HZ for example, only some bits
    were compatible.

    So sorry about that Theodore
    You can have your Ivory Tower as well as knobless
    It is just that knobless and his Ivory Tower stands out much more than yours
