    2002+ ZX9R Gauges - Retrofit...

    So in lieu of my crash, I am taking the opportunity to reto-fit other gauges. I like the late model ZX9R gauges and they are compact with a single plug connection. They also have a coolant temp read out, clock, and integrated indicator lights. It also uses an electronic speed signal.

    So due to me playing around with gearing and tire sizes, I wanted the ability to tweak the Speedo calibration. So I got to thinking.....

    I have the Stites/Couch VFR setup and the Ď94 and later VFR used a similar electronic sender.... so I started buying used senders from the 94-97 and the 98-2006. I broke out my power supply, 5VDC step down converter, and my Fluke Scope.

    Turns out the senders will work on 5VDC and 12VDC input voltage, but internally limit output to a typical 5VDC plane to peak value. So then a fit check was required....

    Fits like the mechanical drive.... Now the last couple pieces of the puzzle are a Speedohealer from Healtech to allow for calibration and an PNP harness to adapt from the ZRX gauge connections to the ZX9R cluster. I also have to swap out the stock coolant temp sensor for the ZX9R sender. The nice thing is that the both the gauge cluster read out and the temp warning light both run off the same sensor.

    So more to come....

    Ah very interested to see where this goes! I would also prefer a more compact later model ZX9r or other gauge cluster... I have a handful of GSX-R speedo sensors if you want to try one - probably the same unit.

    PM me for great prices on ÷hlins shocks and forks!

    I agree this has a couple of advantages as far as I see it (and my KZ has Speedhut):

    - Gauges are cheap (Got a stupid clean unit off of EBay for $85 shipped)
    - Has coolant temp read out and clock.
    - Unless you go with GPS based Speedhut gauge (Which is more than the non-GPS) this makes mounting and integrating a speed sensor easier.
    - Parts are still available from Honda and Kawi.

    So far costs (outside of the Greg Couch and Stites parts)

    - Gauges (Used $75-85)
    - Temp Sensor (Used $20 / New $40)
    - VFR Drive (98-06) (Used $15 / New $80)
    - PNP Harness TBD
    - Healtech Speedo Healer (New $110 / Used $????)

    Edit: Forgot to put the speedometer calibrator in the price...

    Good stuff Cory!

    When switching to the electronic speed sensor, what does it pick up? Do you have to install something on the countershaft to make it work? Itís just a hall sensor, right?

    This is a direct replacement for the mechanical VFR drive and the Stites adapter plate for Gregís 2-piece sprocket cover. Should work wherever the VFR drive is used.

    Cool. 👍🏼 The mounting isnít what has me confused though.

    Iím stumped as to what piece of ferrous metal would be intermittently passing by as part of the countershaft sprocket so the hall sensor could count the revolutions.

    As an example, I have a speed sensor on one of my bikes that is placed within 1mm of the brake rotor bolts rotating around.

    But if it works, it works! Look forward to your progress and I think a modern compact cluster is going to be a great mod.

    Arash,

    It is internal to the speed sensor. It has the same flat ďtangĒ drive as the mechanical. It uses a PTC to trigger a 5VC square wave out to the speedo. Nothing external with a magnet, etc....

    Well they are alive, mostly... Temp sensor needs to be swapped out once it gets here to read properly, and I found a glitch in how the tach works that is going to take some head scratching....

    So the snafu with the tach signal is that it gets a B+ signal instead of a B- like the Rex.... so I am looking at how I can convert it over or use the ZX11 ECU output....

    Like I said, head scratching commencing.....

    So a little help from work with my head scratching, I think I can build a simple NPN transitor based circuit that can take the low (-) tach signal and convert it to a (+) square wave output. Iíll hit up Radioshack on the way home to pick up a PN2222A and some resistors.

    Sorry for posting in old thread. But have you finished this project? Or may be anyone else?
    I bought the same gauges and have a plan to install them to my ZRX. And any info would be very useful

    I have the install working, however I have not finished cutting and powdercoating the mounting plate so I have not verified everything. It you are attempting to install a later set of ZX9R gauges (Full Electronic Ones) you will need a number of items to make it work such as a Stites VFR adapter plate, a 94+ VFR speedo drive, Speedohealer for a VFR800, a ZX9R Temp Sender, and build an adapter for the harness.

    Hello, thanks for answer.
    Yes, I bought gauges from last generation of ZX9R.
    You wrote about problems with signal from ZXR's CDI for tachometer. Was you able to solve it?
    May be you have any kind of electrical scheme for this? Or if you could describe in few words what should be done - that would be very helpful.

    What about speedometer drive - in my case it is impossible to use drive from VFR or even original one due to small distance between fork legs (GSX1300R fork + custom triple clamps), so i'm planning to use hall speed sensor.

    Yes I figured out on the tach. My problem was the zener diode I built into my ZX11D adapter which due to how the ZX9R gauges pickup the tach signal from the ZX9R CDI had to be removed. Now it works properly.

    The VFR speed sensor DOES NOT pickup from the front wheel. If you look at my pictures above, you will see it is connected to the front drive sprocket, just like Honda intended. As far as the wiring, yes I can give you a few pointers. The first being I have not sourced the multi-pin plug for the ZX9R gauge cluster, so I would recommend buying a used ZX9R harness off of EBay or where ever to harvest one.

    I can get my electrical supplier to see if he can source one, but frankly I usually only do that for harnesses I intend on selling.
