Recalibrating the Speedo for 17" Wheels
« on: December 22, 2013, 06:45:23 am »
Hey all,

Considering an SM conversion.  I located this info on recalibrating the speedo.  I love that KTM makes this so easy; my WRR required a separate component to adjust the speedo.

Follow the pink wire from the speedometer under the headlight mask to the connector.

Disconnect connector.

Turn bike on and cycle to where the dash is displaying Mode 1.

Hold both buttons down for about 10 seconds.

The wheel size should now be flashing.

Change the wheel size to 1870 for the 17" wheels.

Press both buttons at the same time again.

Turn bike off.

Turn bike back on to verify that wheel size has been changed (so you don't have to undo the headlight mask and fiddle with the plug again)

Connect plug under headlight mask.

Go for a ride!

The process becomes very easy once you do it the first time. There is plenty of room under the headlight mask to undo the plug. I did not cut any wires and will not. It's just too easy to unplug it and plug it back it in.

Thanks to Buddoggin at Thumpertalk for this concise tutorial.

If anyone does this, I'd love to see some photos of the surgery.  Specifically, I'd like some photo's of this wire that needs unplugging.

**See below: another source claims it's better to simply cut the wire at pin 18, and never have to unplug anything to change between wheel sets.

So im trying to recalibrate my 08E speedo and im having a bit of trouble. There's no pink wire, so I consulted the manual. It says to unplug the main harness the joins up to the computer and the pull pin 18A. Mmmmk, so there's a pic too, but its fairly dark and unreliable. So I then flip back to the wiring harness diagram, to try and locate that exact wire. I can find a bunch of different things that plug into that harness, but not the speedo sensor. Anyone know which color wire to unplug so I can reset this damn computer finally?  >:(

I wonder why the speedo requires ANY wire to be manually plugged/unplugged.  You'd think this would be a completely electronic issue.  Anyone try doing this without unplugging the wire?

So I did the unplug/reset operation my manual described. Yikes, those little wires are delicate as hell. Almost destroyed it trying to put it back in. Yep, the computer cooperated once u unplug that lone wire. Wierd, why wouldn't they just have it as a regular option in the computer? KTM frustrates me sometimes.  :-\

That would be a great product idea!  I imagine that a quick disconnect would not be very hard to manufacture.  You listening Tumbleweed?  You could call it the Chameleon!

Might not be KTM's fault, I wouldn't be surprised if a user tamper proof speedo/odo is a requirement for federal approval here in the US.

I just read the following from the BlakeBlog (http://sobiloff.typepad.com/blakeblog/ktm-690-enduro-faq.html)

Adjusting the Odometer for Different Front Wheel Circumferences

Remove old Odometer and the connector.
Cut the wire for pin 18 (should be Brown/Grey for 690E) on the connector.
Install Odometer
Turn key to "on" and with the meter set to "Trip 1", press and hold "Mode" for 10 sec.
Length xxxx (the 17" circumference) will show up (flashing), press "mode" to increase and "set" to decrease the circumference.
The correct setting for 21" should be 2205.
Press "mode" and "set" simultaneously to set it.
The only thing that the "pin 18" does is lock the Odo from adjusting wheelsize.

***The upshot is: Once the wire is removed, there is no need to re-install it!!***

I need to figure out a way to take that pin in and out without messing up the connection port. I plan on switching out my 17s for my enduro setup quite frequently... so, WTF. I know you can take those fragile pins out only a few times before it's game over. Any ideas? ???

I've not seen how the pins are set up yet.  Is it not possible to simply pull pin 18 and zip tie it out of the way?

Hmmm. Next time I pull that pin I'll leave it out and see if the speedo will work w/o it being in. It'd be a helluva lot easier like that. Anyways, the rotor bolts are chewing the heck outta my speedo, so it ain't registering right. I got another speedo coming and I'm gonna have to either shave down the heads of the bolts or figure something else out. So either way I'll be messing with the computer again, and when I do I'll get back to ya'll.  ;)

Yup! Speedo and electronics work 100% fine without the pin in the plug. I carefully removed it, and taped it back. I can switch between SM + Dirt very easily.
