Hi guys, does anybody know what's involved in carrying out the wiring mod on an nc 35 track bike, I've removed the speedo and the bike is going into limp mode at 5500rpm, I believe this is because the ECU is not receiving a signal from the speedo, any help greatly appreciated.
Cheers.

I use the live wire to the rear brake light and splice that to the Orange / black (blue) to the CDI (sorry can't remember the second colour on the Orange )
If you have a race loom you may need to look elsewhere for permanent live. You may also need to loop out the side stand switch.
