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.
