Magnetic gear indicator

[Killer Rat]

Has anyone tried to use one and do they work?

My main concern is that the 2 sensors would have to be positioned pretty close to the magnet on the gear lever to get an accurate reading on the indicator. Will this product work well or just a cheap crappy mod thats not worth the money.
I would like one, but cannot justify the expense of the Datatool version for a small bike.

Thoughts?

I've never tried one but when I first started riding I thought gear indicators would be a good idea and they should be fitted as standard. Not having one, I used to count the gears up and down and keep a mental note of which one I was in.

Now, although it's not long since I passed the test, I find I don't think about what gear I'm in. I automatically change up or down to suit the circumstances and an indicator would be redundant. It's surprising how quickly you can get used to listening to, and acting on, the engine sound, even on a strange bike.

i cant see it being too hard to setup correctly ....
its working on the same principal as a magnetic speedo a magnet passes a hall sensor that sends a pulse to the chip telling it to increase or decrease the number displayed

......hmmm my bikes stock gearing from 2nd to 1 st is very harsh and i lose count of the gears when im down shifting this might be usefull to me

Mmm, it's the sort of thing that I'd be inclined to bolt on for the lulz, but I doubt if it'll be 100% reliable and if it's not then you might as well not bother. Rev counter FTW.

for the sake of £15 im tempted to get one just to try it out

i can see it getting confused when false gear changes, pushing the pedal but not actually changing gear, etc.. but overall it should be ok. will depend on the position of the magnet of course.

think i'll give it a punt and have a play

thanks for replies guys.

I did reckon the sensor+magnet would have to be pretty close to be accurate, got some machinery at work that has the same sensors on it and they are no more than 5mm away from the magnet for the machine to work.

I think i'll give it a try and see what happens.

Just bought one, thanks for the head up. The ZZR600 goes through to 14000 rpm and its hard to tell what the hell gear its in when.... having a little fun. I'll post up a report when its fitted.

Never felt the need for one, after all....If you "pin it" and it takes off like a scolded cat ..... you're in the right gear...

I also though a gear indicator was 'just a gimmik' until for 4 weeks BMW loaned me a (new) F800R while my '04 F650CS was having some attention. The loan bike had a gear indicator and I have to say I USED IT and found it and found it useful. Despite the bigger engine in the loan bike it was more critical of being in the correct gear than is my 650 single 'thumper'. I stalled the 800 a few times when going slow at junctions before I learned to use the gear indicator

IIRC they tend to misread because of the lever vibrating whilst riding.

I was thinking about one once but when I looked into them a couple of people said that they just misread all of the time and weren't at all worth the money.

If you've got a newer bike, the indicator has a passthrough onto the ECU wiring loom and reads the gear directly from the ECU.

Accumen only works when the clutch lever is released though.

Package arrived about four days after purchase, so not a bad service.
I'm in the throes of re-fitting the workshop so I've not had time to actually install this, but did a quick 'offer up' to see what I had got:-

The package contains a one inch square plastic box with the LED readout and its connecting loom, two hall sensor blocks with their wiring and a small oblong magnet. On the zzr6, it is easy to mount the sensors on the frame (I used double sided adhesive tape, Araldite once everything is prperly positioned) and the magnet on the gear linkage rod rather than the gear lever itself, it all hooks up as per the wiring diagram but you will need soldring iron and shrinkwrap to do the job properly.
It works fine, except I have to find the earth side of the neutral switch to give me the neutral zero indication. This it would appear, will mean stripping the front fairing off to get to the neutral light connections.
For the price it works, but it does take quite a bit of fitting work to install it.

I presume it somehow resets itself when in neutral......... if it get's mixed up. Might not do that until you've connected the neutral switch wire.

I've had a few bikes that could have done with one, the CB-1 could do with one as I'm always looking for another gear in top.

Not much use on a lot of bikes I s'pose.

mine arrived too but i've had no time to play with it yet.

if this w/e is dry i might venture out and give it a go

Hi
Been a bit of a delay getting round to fitting this, mind you, I can now fix washing machines to add to my other 'talents'.
I rough fitted everything up again and it certainly reads gearchange movement acurately, pickup sensor placement is a bit critical but not overly so.
My mission was to get the neutral switch in circuit, this 'earths' the device and resets the readout to zero.
After grubbing around in the greasy sprocket area to get the neutral light switch lead off(ZZR600, might be different on other models), I spliced in the lead to the gear indicator unit. Not a sausage, it would not zero through the neutral switch, but was fine when earthed to chassis. Measured the resistance through the neutral switch to earth and it came to about 100 ohms, varied a bit with a wiggle of the gearlever. Every now and then it would zero correctly, but not reliably.
So, this device needs a clean earth to zero properly, it would appear that (my) neutral switch has gone slightly high resistance. This would probably not affect a newer bike immediately, but time and wear and tear would (I think) give rise to this problem eventually.
The solution is to make up a small switching unit, sensing a drop in resistance on the nutral switch to turn on a true, hard earth.
Jotting a few ideas down, lets see if anyone else has a simple and elegant solution.

surely the neutral switch is only earthing the bulb tho? as in the bulb would be supplied with +12v from the ign switch and the neutral switch is going to switch to earth so the resistance you measured would prob be the bulb? or a bad earth perhaps..

Hi
I spliced into the neutral light switch about two inches from the switch connector. Measured it as about 100ohms resistance through the wire, and the same on the switch connection. No doubt about it, the switch has a low level of resistance, not enough to bother a small bulb but the gear position indicator obviously needs zero ohms to reset properly.
I am going to get a 12v relay, wire the coil from pos to the neutral switch connection and the indicator earth wire to the normally open contact with the other side going to chassis earth. When in neutral, this should earth the relay coil, activating it, closing the contacts and giving the indicator a good solid earth.
Simplist and cheapest I can think of, I'm not going into PNP transistors and all that extra complication.

Cheers
