The speedo on the Tenere is about 9% out. I was not too happy with this and when I changed the front sprocket to a 14 from 15 it got worse.
I like to know how fast I am going due to the masses of cameras in London.
I previously noted that the bike was doing 70 (GPS) when the speedo was reading 77 so some quick calcs:
70/77 = 90.9 x 14/15 = 84.8...... a 15.2% error.

I decided to fit a speedo healer at a cost of about �65 including postage. Small change when my last speeding fine was �550.

I decided to take pictures of the fitting to assist anyone else contemplating fitting one. My tank was half full when removed and did not spill any petrol at all.

First, all the grey plastics have to come off.



Beware the small spacers, they fall out and have a mind of their own.



Next is the rear tank bracket, again, watch the spacers, they fall out when the tank is lifted.



Remove the front long silver bolts from under either side of the tank and also the two black plastic brackets in front of those (3x 8mm bolts each). At the same time, slip off the tube on the left side behind the long bolt. Mine did not spill any fuel. Note the rusty thread on the bracket. It was the same both sides and made romoval of one of the side panels a problem, had I left it much longer I am sure it would have seized solid and broken away from the bracket - rust inhibitor used for reasembly



This is the hard bit. wiggle the tank up whilst keeping it roughly level and get someone to chock the rear up with something so you can get to the fuel line and electrics. The green and white plugs are simple enough to remove with the usual press catch on one side.


Now remove this clip from the fuel line and it will allow you to then squeeze the blue tabs on the fuel line and pull it off.


Now lift the tank off. This is what it looks like underneath.


Now you can access the speedo sensor cable. Its the 3 pin white one above the tappet cover, centre screen. Pull this plug apart. Care is needed when pressing the catch as it is a bit like a fish hook and the plug needs to be pushed together slightly before pressing the catch and then pulling the whole thing apart. (hope this makes sense).


Once apart it is a simple matter of inserting the male and female of the Speedo Healer lead into the now exposed female and male of the existing plug.
All that remains is to plug the new lead into the Speedo Healer, plug in the supplied extra 2 pin lead and switch (not absolutely required unless you want to know you max speed recorded) tidy it up and find a place under the seat for the Speedo Healer bearing in mind that the buttons need to be accessible (not easy if you have other bits attached under the seat) and then calibrate it to suit your set up.


This is where mine ended up. I may move it yet. I have a relay, an Autocom, an MP3 player and battery pack squeeze in too, so space is tight. This is probably my main criticism of the Tenere when you consider its intended use.


The settings are (for my bike anyway) -9.1% for the speedo only and -15.2% with the smaller 14T front sprocket. Follow the instructions sullplied to program it.

I will calibrate the unit and test it against TomTom tomorrow. I'll let you know if it is any good.
