SpeedoHealer

[Globalrider]

Interesting .......and not trying to advertise but!
From Pashnit............."On most modern motorcycles, factory speedometer over-reading could be as high as 10%. So even a modest gearing change can have the speedometer off by 15%. Changing the sprockets will also result in higher odometer reading, decreasing resale value without valid reasons. The SpeedoHealer is an inexpensive, convenient and very simple way to sort these speedo and odo issues. The SpeedoHealer is the most popular and reliable calibrator in the world â€" acknowledged by thousands of happy customers worldwide."

Might be worth checking out for those that have "issues".

Got one on my Bandit ...
I fitted GSX-R electronic speedo in place of the cable driven clocks. Used the Speedo Healer to calibrate them as they were reading 10mph out at 30.

They work a treat. Fit, calibrate and forget

[Blubber]

Yep, what froudy said.

Easy to use, fit and forget sums it up nicely

Easy to install and easy to set with GPS. My 14 showed 15% too much in 100 kmh with 17 teeth front sprocket.
No wonder my bike was SO fast before adjusting the speedometer!!

Had one on my 14 to correct the "inbuilt variance" from Zooki - well worth the money.

I'm sure they are a good thing, but the explanation in the OP is slightly misleading.

Speedos (ex factory, and mostly for legal reasons) typically over-read.  So if it says you are doing 100 you may only be doing 95 (for example)

This is a good thing when it comes to speeding ticket accrual... as long as you don't compensate for it and ride everywhere at 1110 ! 

Some changes in sprockets, tyre profile etc may in fact push the formula the other way making the speedo MORE accurate than it was.  It all depends on the actual changes involved.

The fact remains of course that a speedo healer is the only way to have an accurate speedo - , unless changes you make happen to conspire to bring it to very close to actual, which is quite unlikely.


But isn't THIS a problem.....

Compatible with all motorcycles with non cable driven speedometer.

Problem with the 14 speedo is that is generally a minimum of at least 8% out if not more as standard, so at higher speeds it's wildly overreading. Good for the ego, but bad for knowing realistically what it should say - the only way is to compare it to a Sat Nav. Mine for instance would read 90mph when in fact the true speed was 74. That to me was unacceptable and why I fitted one. Adjusting gearing only exasperated the issue.

Frankly I wanted a readout which at speed was true to within a couple of mph, not wildly optimistic.

Part of the problem on the 14 is that it's a needle style readout, digital speedos on later motorcycles are more accurate.

Snap Dave.

[VladTepes]

Yeah but our bikes have cable speedos don't they (memory fails me) and these say they are for electronic ones only.....

Of course I could be wildly confused.

[KiwiCol]

Tooooo much Brandy there Mike, definitely an electronic speedo - it plugs in down by the clutch slave cyl.

[gsxbarmy]

As Col says!!!

[VladTepes]

Hmm funny... I think actually not ENOUGH brandy !

Probably confused in my head because I've been looking at the disaster in the corner of my garage that is my CX500..... really must fix that one day....

My speedometer died on last weekend. It worked ok over 200 km in this spring, and then it started to show less and less until it was almost in zero in about 50-60 kmh. I searched the fault and finally found it. It was the Speedohealer what was dead. And to be honest, it was my second dead speedohealer. The first one worked two weeks and about 500km and this second one worked about four years and 40 000 km.
Now its disconnected and speedometer works again.
Speedohealer was a nice toy with smaller front sprocket and bigger rear sprocket, what I used to have with naturally aspirated engine, But now with turbocharged engine I have enough torque to use standart sprockets again. So I dont need that Speedohealer toy any more, never I hope.

That's interesting T24.  I've got a speedo corrector as well, not the same brand, but a similar thing, sml circuit board, couple of buttons & a plug.

You say 2 have died, did you mount them in the same place? Probably.

I know it doesn't matter now, but reading the symptoms you mention, I'd say it was being rubbed / knocking against something (occasionally) and adjusting itself down. The vibrations of the bike running could cause the wee buttons to be pushed & adjusting the input to a huge extent.

I wonder if there's a factory reset for them, or just pust the buttons to adjust the speed back up.  Maybe?
