Removal of key & ignition??

[HUTCH55]

Does anyone know what you need to do to the wiring loom to remove the need for the key and ignition barrel? Is it a big job and can I use a k5 wiring loom on a k6 bike? I'd sooner attack a spare loom knowing I can always put the old one back on if things go wrong.

Cheers.

Curvy switch uses 3 pairs.

Pair one is main live, replace this with a switch or relay run through killswitch or whatever.

Pair 2 is "immobiliser" replace this wire with a 100kohm (iirc!) resistor going to earth.

Pair 3 is parking light. Ignore...

I'll have to check to see if the injected is any different. Nothing's simple is it?

Hell no, but that's why you should've bought a curvy :-D

You could have a point there! Could have had a wet AND dry bike instead of just the one.

You will find a 100ohm resistor in the switch which if removed will inhibit your bike starting (it will spin up though).
Either leave the switch in or fit another resistor into the circuit once the switch is removed.
I speak from experience, make sure it is well protected and insulated otherwise it will break down due to the vibs etc this will then cause your bike to stop.
The bike I,am now building may well have the key switch left on.
Hope that helps, Pipey

Cheers pipey,

don't know what to do as yet, like you a lot of people have told me to leave it as it is.

Oh, and thanks for trying to tell me my radiator had gone at brands gp. Could have been a bit of a problem if we weren't on last couple of laps.

Thanks

YC, the pair 2... what colour wires is that?

Orange/red to the ECU and black/white to earth on all curvy models.

Sweet cheers... remote start here I come.

The 100 Ohm resistor information would have been nice to know a few weeks ago. I just put in an aftermarket, much much smaller key on my SV before I realized something magical was happening inside the stock key housing. I finally figured out the the O/Y and B/W wires needed a 100 ohm resistor. If anyone out there wants to put in an aftermarket key, or a hidden toggle switch instead of a key, then do the following:

There are 3 paired loops:
1) Red and Orange
2) Orange with Yellow and Black with White with 100 ohm resistor
3) Gray and Brown

Pair #2 and #3 may remain closed at all times. Pair #1 is the only loop that needs to be turned on and off. Pair #1 can be wired to an aftermarket key switch or toggle switch, provided you solder a 100 ohm resistor (found at radio shack, 1 watt is fine) into loop #2. Hope this helps someone.

Here's one I made earlier. In this case resistance is not futile. And 100 ohms resistance epitomises non-futility. You can tell where it needs to go by measuring resistance in the ignition barrel. It took me 2 nights afer work to figure it out. But I'm no electrician.
Now the kill switch does everything. The whole ignition runs through it.
