After looking at various tacho options for the XTR I went out and brought the Jaycar Digital Tacho Kit. Put it together over the weekend and tested it's basic operation this evening - obviously my old electronics skills haven't yet disappeared and it worked fine. Honestly it's not really a difficult job as long as you can follow instructions, can read small writing on components and aren't colour blind - oh and you can solder sucessfully as well :icon_rolleyes::icon_rolleyes:

The red LED display seems large and clear which together with the auto-dim feature and the 7 section green bar-graph display (complete with 3 section red-line feature) should make this a fairly satisfactory add-on. While the display can be programmed I've left it standard other than setting the configuration to single cylinder 4-stroke and the red line to 7,500 - this means the first green bar-graph segment covers 1,200 revs with the remaining six at 900 revs.

The box is a little on the large size but I think that I should be able to squeeze it down into the cavity formed between the current multi-function display unit and the windscreen. One issue however is that the jiffy box housing isn't waterproof so I'll have to add an additional thin clear perspex cover over the top-plate and seal the edges with a suitable sealing compound.

I've looked at the wiring diagram and although it looks like I should be able to simply tap into the loom for power supply and ground - however I was relatively suprised to find that although the multi-function unit can display rpm in diagnotic mode there is no direct tacho feed from the ECU (unlike the Tenere). So it seems that I either have two options either tap into the ECU / coil connection (orange) or find the relevant ECU tacho feed.

Any comment from anyone who's already done this would be appreciated.

I'll post photo's when I've managed to find the time to finish the installation.
