Using the old dashboard circuitry to maintain the functions.
« on: December 21, 2016, 06:13:24 AM »
Hi I'm new to the forum and this is my first post.
I take the opportunity to say hello to the all Comunity.
I've acquire a beautiful K100RS last year with the intention to turn it into a vintage looking bobber.
The dashboard being so bulky had to be replaced with smaller unit, I went for a combo speedometer and tachometer Daytona Velona.
Unfortunately this meant that I will loose all the extra bits that where incorporated in the original dashboard.
This is when I wondered if anyone had successfully reused the circuits boards from the original unit and somehow incorporated them just like with the speedo sensor chip.....

Hello and welcome to the forum from another Brit.


Everyone will want to see pictures of the beauty you started with and the current configuration.  Half will commend you on your design genius, the other half will give you stick for turning beautiful to ugly - brace yourself!


There is a lot of information already here about the dashboard/instrument cluster so make sure you try some searches for the info. I can't help you with that issue as I'm one of those who favours tailoring my K with bolt-ons rather than by cutting bits off.

Welcome! Put the year of your bike in your profile, too, so it will show up in every post because there have been a few variations throughout the years.

I thought dilapidated bikes—not beautiful ones—were used to create bobbers, instead of the reverse
. Just goes to show there's more things in heaven and earth than are dreamt of in my philosophy.

As far as adapting new instruments to reproduce functions of the originals, take a look at the reference links in reply #4 of this recent thread. These are only a few of several discussions concerning your interest.

Thanks everyone for the suggestion, I've follow the traces on the dashboard circuit and it locks relatively simple. I will try to hide the boards inside the front light and part from a dyod that can even be reused from the cluster there is nothing else separating me from having the reserve warning light function restored. For example....
I will post the result when if I getting working.
