I'm interested in changing my 87 K75 factory instrument cluster for something different. I would consider separate vintage style analog Speedometer and Tach with LED lights for other functions/alerts like temp, neutral, fuel low level, gear, etc,..................or...............would equally consider a full digital M/C panel.

I'm guessing that everything on the factory panel is electronic,.....so don't know if this is possible. I've considered one of the retro style speedos with a magnetic pickup that mounts on the fork tube,....and a magnet on a wheel spoke. Don't know if there is a Tach that would work with the K75 3 cylinder.

Anyone done this with either a digital panel or analogs?

I'm in the middle of a construction project which will replace the instrument cluster on my naked K75 with a Motogadgets Classic speedometer.  There are others on this forum who have done similar using the Acewell speedometer.  It is doable with additional circuits to replace the ones inside the instrument cluster that are necessary to perform mandatory actions, such as enabling the start circuit, simulating the Neutral light, displaying the turn signal indicator, etc.  Have you selected the instrument cluster replacements yet?  There is Motogadgets , Dakota Digital , Acewell , Autometer and VDO to name a few.

The magnetic sensor on the front wheel will work. There is a circuit floating around which allows the OEM speedo sensor to be repurposed for use with a modern speedometer.

Of the manufacturers I mentioned above, many produce analog speedometers that integrate digital tach functions.  For example, the Motogadgets Classic has tach input but no means to show current RPM.  Instead, it reads RPM values from the input and performs two functions with the information -- alarm when readline is encountered or exceeded and gear indicator.  You'll have to investigate the various options available with the instruments of your choice to see how you can fashion a replacement instrument cluster.  It is useful to get inspiration from Larry Romestandt's work (http://specialks.net/ )

In terms of what I choose,......ease of conversion/installation would be a big factor. I have looked at Larry's page. He builds some beautiful bikes.

Hello,

I see that you decided already you´ll go for vintage style, however I´d like to tell you about my updated Instrument project...

I´m in the middle of an University project to get the instrumentation of bikes like ours way more advanced than modern bikes...

As I briefly explained on my introduction,

The idea is to gather all data from the bikes sensors using Arduinos and use it to make fuctional a very complete OEM instrument panel for the day to day use and add an Android BT device to present SCADA information, log data and probably use it as Crazy Frog suggested as a Diagnosis tool... 

I´d add an accelerometer to de signals and maybe more.

Any help/suggestions'd be appreciated

Regards

Izzy

 Very Happy

If you go to the motobrick.com site and have a chat with Wmax351 he has done a lot of work on that stuff already and is a very clued up guy.

My k75 is a naked one... nowere to proyect the info... 

My idea is to feed the camera in the backround something like this:

Robert, sent you a PM on your circuit boards.

All, I'm leaning towards the Dime City gauges, mostly due to price and their extensive selection. I would want a speedo and tach. However, I am also intriqued by the Trail Tech Vapor or Vector instruments. Cost is similar, $200ish with mounting brackets etc.
