Deristriction
In standard trim an NC35 is
restricted to 180 kph :-(
The restriction is controlled by a sensor in the
speedo. This can be removed fairly easily, and there is no need to spend 50 odd
quid on a "black box" :-)
- First remove the speedo assembly - two 8mm bolts, speedo cable and two
connector blocks. - Remove the cover from the speedo - Lots of black posidrive screws plus the
odometer knob. This is held in place by a tiny posidrive screw in the end. - Remove the speedo unit - undo 4 silver posidrive screws at the rear of the
assembly. - You should now be able to see the sensor. It is a cam shaped disc attached
to the speedo drive, which makes contact with a metal strip (connected to one
of the two wires that come in through the back of the speedo) at the magic 180
kph. All you need to do is bend back the strip so it NEVER makes contact with
the disc and voila: the bike is derestricted.
You will also see
that the two wires entering the speedo are connected together by a resistor.
This is just to tell the bikes electrics if the sensor has been disconnected,
and if it is not in the circuit causes the bike to misfire above 5500
rpm.
Disclaimer: If you knacker your speedo whilst doing this
don't blame me coz I accept no responsibility for anything at all. Also the same
applies if you get done testing that the derestriction works on public roads.
