speedo healer

as the ,name suggests,just bought one.

can`t believe how much the speedo was out by,7-8km/h at 100km/h..so by my speedo,i`ve done 152000km ,but I can take 10 000km off that in real terms.

calibrated by gps,and am really doing alot higher revs than I thought at true speed.

thought 3600rpm was 100km/h,but really 3850rpm,and getting ready to go back to 3 teeth bigger on the back again,so will be curious what revs i`ll be doing at 100.

Like the big cog,nice and snappy,but this will be for the philip trip, maybe a bit silly for the amount of K`s i`ll be doing on the return trip,somewhere around 7000km`s,but want the snappy thing for the twistie trip down and back,as I want to avoid the plan straight drive

Got a link for where you got this from mate?

^^use this link to calibrate,very usefull

I found I had that same error ~ 6%-7%. But, despite the speedo error, on the 1250 the odometer is pretty accurate. You'll find with the healer working, your odo reading for distances will now be quite a way out compared to distance signs, google maps, etc. It also means your oil changes might need to be brought forward (or just change the oil midway between servicings, which can't hurt).

you lost me there!!

in theory,one should control the other?

i know it takes 36sec to travel 1km at 100km/h

As Ewok says the odo is pretty damn close.
Why the difference? I dont know.
(with standard gearing)

This suggests that they are deliberately made to read high, the pulses are correctly converted in the speedo to the correct distance and it deliberately calculates a high speed.

mine was never spot on,thats just going by the 5km speedo checks at the side of the road.

mines about 4km/h out by these checks, but, almost double in real terms by the speedo now its been corrected

you got me thinking now, will certainly check it against those markers to see if it has changed

odometers are accurate, very much so. speedometers are inaccurate because of ADR requirements that they read high (minimum 4km/h if I remember correctly) to avoid any potential error based on average discrepancies. I just use GPS all the time to ensure speed is right (and then know the correction on the speedo). Another alternative when you know the correction is to make a new face for your speedo. There's a guy doing custom GS500 speedo and tacho faces in the US, has even made corrected versions of them so they account for speedo error. Here's a sample:



Before and after:



He's doing these for the GS500, $12 shipped to US, Canada and Aus, I'm considering a set for my GS500, will even do custom graphics in the dial area if you want, just send a picture file.

Be nice to be able to do some for the Bandit.

ok,i`ll have to put a floor in everybodies theory..

i disconnected the healer,and put the 48 tooth on,and after the 5km side road speedo check near where i live,before and after with the 45,and 48,the odo(along with the speedo) is way out with the 48 compare to the 45,and i cant see how it can be any different ,given all the signals come from one point,and are transfered through the one cable!!

i personally wouldn`t change the dial as i`m always changing the gearing..speedo healer for me

Mine has been checked against a couple of GPS's and has a similar error to what others have reported.

You will need to do a lot more than 5km for the ODO check.

The ADR (18/03 5.3) on speedos (post Jul 2006) allows for up 4 kph plus 10% of actual speed (over reading). Under reading is not allowed - your speedo cannot show a speed slower than what you are doing. The rules allow for example that if your vehicle's actual speed is 100kmh, the displayed speed is permitted to be anywhere between 100 kmh and 114 kmh.

Because the reading can be affected by numerious things, gearing, tire pressure, load, tire wear, even the width of the speedo needle (on the 1200's that is), it does seem a little superfluous to have a recalibrated dial face that will be out of spec as your tires wear down. The Healer seems to be the more accuarate solution that can take into account all the factors and can also be re-calibrated if things change or wear down.

I don't know why the speedo and odometer read differently, however I have noticed this myself, with the speedo tuned in right with the Healer, the distance posts show the od as inaccuract.

And there are 1250 gauge faces out there, we don't need to worry about the speedo face as ours are digital of course. Not as cheap as the US version mentioned above, I got mine from Germany, I added a little graphic above the speed readout as it was blank previously.

no..over a 5km stretch,with 48,it over reads by about 500meters,and with the standard 45,it over reads by about 250meters (both the odo and speedo)
this was with repeated runs

you shouldn`t need anymore than that,as that would suggest the speedo is erratic and unpredictable

Ok you got the special one

must do.. or its a 1200 thing not a 1250 thing

Hi,
Not to get too technical but from ADR 18/03, at 5.3, we get
there shall be the following relationship between the speed displayed (V1 ) and the true speed (V2).
0 ≤ (V1 - V2) ≤ 0.1 V2 + 4 km/h
Therefore at a true 100kmh your speedo can read anywhere between 100kmh and 114 kmh.
That's what you get for having people look after you.
Cheers
Mark

Yeah about 3500RPM is close to danger money. 4000RPM where the 1250 likes to sit is in danger territory.
I find I read the tach quicker than the digital speedo.

i figure I can sit on 10k over and I'm still safe.

5% for a bike is pretty good these days. my bmw was 9% adn the sv650 was 8%. (chaning tyre size brought it down to 3%).

if you look at the published specs, 3250 in 6th is a weird number. 3500 is more likely. ditto for other speeds/revs.

I put the GPS on mine coz I reckon the GPS would have to be spot on. So here is what I came up with.

Speedo / GPS
67 / 60
87 / 80
107 / 100
120 / 110

Yep same to within a poofteenth

ditto that.

Got a feeling that it's a government requirement for Australia. Young blokes Hyosung is exactly the same. Wife's commodore is not quite the same but close.

I kinda see it this way:

1) Speedo cannot let you speed accidentally (legal loopholes etc).

2) they have to factor in tire profile (high profile would effect reading and cause you to speed)

3) manufacturers can say bike goes x kph. when it doesnt but it looks good on spec sheet.

4) maybe safety - slows people down (except cars start beeping you for going under the limit).

The downer is that the bike says you are doing 200+ when you probably arent.



Guys - is the speedo a straight 7k's over or is it a %?

the bmw and SV I had was a %. at 60 you were doing 66, at 70 you were doing 77 etc.

It's in the ADRs that the speedo is not suppose to read under (i.e. show a speed slower than you were acually travelling), and the ADR allows 4kph plus 10%. As mentioned before this means an actual speed of 100kph can register on an ADR approved speedo (car/bike etc) anywhere from 100 to 114kph but never below 100kph.

Where you get caught out is when you say to yourself "I know the speedo reads high by X, so I can travel that much faster and be safe". I don't think any speeding fine is under the cost of a Speedo Healer (eBay at $130 currently, could be cheaper direct from the States), a very simple installation and value for money addition IMO, plus you can recall max top speed if you add the little switch.
