looks great, as you have fitted yours with success, could you advise on a few things, i have partly fitted my koso rx1n to my honda vfr400 nc30, but i have a few issues-

1- rpm doesnt seem to pick up? currently wrapped around the ht lead, any ideas?
2- is seems to have restricted the power of my bike, any ideas?

I'd try to fit a properly insulated, soldered connector in-line somehow. Wrapped leads don't give a very consistent connection and if you notice a power loss I'd expect you're leaking charge in a way that give irregular firing at higher RPM.

Can you see any scorching near the pickup point on the loom?
Does the power return to normal if you remove the clock?

Which ignition wiring set do you have, A, B or C?

Thanks guys.

Ill remove the clock and see what happens.
I did try and connect the RPM directly to the CDI by connecting it to the green and yellow wire as per the nc30 wiring guide but it didnt pick up the RPM at all????

Sorry, im a novice when it comes to tech with bikes, what do you mean by which ignition wiring set, a, b or c??

I have noticed on this site that someone else had the same issue that when they removed the factory fitted clocks the bike went into 'limp mode' could this be the issue re power etc??

Thanks guys appreciate the advice................

Use the B set wire and connect to the coil pack on the left side. The spade connectors go on the right connector on the pack and the earth can connect to one of the 8mm bolts.

Without the OEM speedo you will need to do the resistor mode otherwise the engine will not run above 5000 rpm.

Superb, thanks, Please forgive me for being dumb but do I need to do the speedo end and Cdi end or one or the other as the link shows both

Only one end, whichever is the easiest.
