Does anyone know how to derestrict an NC29. Understand the restrictor is in the speedo but not sure and want to remove it. Cheers

You can either do this:

or another easy way is to buy one of these that screw into the back of the clocks:

Both will derestrict it

Is the NC23 also restricted??

If so is it the same fix to derestrict it??

If your NC23 has a blue lable CDI then yes it is, simple fix is the blue KMH convertor or get a gold label CDI

Thanks for that Yakama, the guy i got the 29 off took the plate out of the clocks already so all i need to do now it the resistor mod but couldn't find it lol.

Thanks
Adam

not all NC23s are restricted.. the old Aeros are NOT.
the 1989 NC23 can also use the resistor mod.. if you google "CBR400 resistor mod" you will find my DIY how to images.. just like the one already posted which is the nC29 version i did years ago. .

Hi thanks for that, will give it a go at the weekend.
