Installing an IMO on a G/S

[GS Weissbeer]

The old speedometer was getting a bit tired - didn't show correct speed and the trip-meter could'nt be reset. So I decided to install an IMO computer on my monolever.

In this thread I will show you some details of the installation.

The IMO is mounted on a adapter plate like the one below from www.bmwboxersupplies.com (To fit the G/S it required 2 small homemade brackets.)

The "interface" print board for the IMO should be placed somewhere protected from the elements. For this I made a small alu plate to fit an existing bracket on the frame.

The box for the print board is attached to the alu plate with strong double adhesive tape normally used for carpets etc. For extra safety I also use a velcro ziptie around the box and frame bracket.

To support the wires going into the box I zip tie them to the alu-plate, which has since been supplied with small holes for the zip ties. I don't have much space or even a work table, so the G/S was used as a platform for the drilling work

Still to be done is mounting the sensor and magnet for the speedometer to function. For this I just found some very good inspiration on advrider http://www.advrider.com/forums/showthread.php?t=314264&page=2

I'll report back when the work has progressed some more

Regards,

Dan

I'd love to know what make the handlebars are?

Conical Magura handlebars

I'd love to know what make the handlebars are?

The handlebars are conical Magura AX. I bought mine second hand but I believe that Touratech sells them.

I got the mounting clamps from a local MX shop and mounted them on top of the original ones. Sometime in the near future I will get some bar risers for better off road handling.

Thanx, I've seen some of these in the local Polo shop. I need to mount them on risers that also move the bars back a little as the Acerbis hand guards rub the clocks/screen on full lock.

A little progress

I borrowed a lathe and made a small housing for the speedometer sensor which fits where the cable is normally connected to the gearbox. The housing is made in aluminium and the speedometer plug from Touratech is glued on. I also prepared a small axle which fits in the gearbox/speedometer drive. A magnet will be mounted on the axle via a small bracket and then the sensor will detect each time the magnet passes by. I have to thank 'cnycl' from the advrider thread above for this brilliant idea

Regards,

Dan

Even more progress

Today I got the sensor house mounted on the gearbox. In order to make room for the sensor I had to use a dremel grinder on the lower part of the airfilter box.

That is so so cool hats off to you, I had followed the links to the plumbing solution, and thought that was nifty. But yours is shear class, well done :
Please let us know how accurate it is, short and long journeys

GS weisbeer,

I have to say your adapter is much neater than mine. A real nice job and seems like will last longer.

I also have another nice solution for remote controlling of IMO from the handlebar. I'll post pictures of it here soon. Hope you'll like it too.

Some additions to GS Weisbeers comprehensive IMO thread.

I think a remote control is a must to get the most from IMO.
TT solution is expensive for such a simple switch and in my opinion it is not easy to use .
Here is the schematic for electrical connections. Note the position of diodes if you're going to use reset switch in your set up.

and below is the photo of my first attempt of an IMO remote switch

it is easy to use and cheap as a DIY project but in time I realized that a remote reset switch (round switch in the photo) is not really necessary and the set up can be carried to a better, protected place.

Here is my final solution which was put together in 30 mins in the early morning before a long trip (sorry for thr low quality photos). While building I thought I'd work on in later but since then it works so well and still serves as it is put together so I don't think I'll play with it any more. A simple bracket is made and it is attached to clutch lever assembly using the bolt underside.

Switch location. It may seem inaccessible at first but one finger operation even with gloves is no problem. Flip your finger forth and back, that's it.

Underside view. This place is well protected and hidden. Some minor weather protection is applied to toggle switch by using shrink tube.

Finally the IMO itself in its cradle working happily
