Removing the ignition key cylinder..

wire the handle bar kill switch to be the ignition switch, you will have to test the stock switch though, Suzukis and Kawasakis need a resistor inline with some wires as well as the normal power wires

[J Farrell / Speed Tech Motorsp]

That is correct. The Kawasaki & Suzuki ignitions need a resistor inline when you wire them. It's theft prevenative system. That way if someone were to just cut the wire harness they can't get the bike to fire because it would be sending too many volts back to the ECU. The ECU would then stop the ignition & fuel from working. It needs the right amount of voltage to the ECU being sent back on one wire or it won't work.

If you have a Kit blackbox installed the resistor doesn't need to be in place since your obviously racing the bike anyways. There is a little wiring trick to getting it to work properly to the kill switch. Cutting & resoldering a few wires will have to be done to make that work.

Yep, the older Honda's have the same thing, but it's a separate line (pink) which needs a 3.9v zener diode.

anything wrong with leaving the key switch on the bike?
my old bike and 04 r6 when i bought it ,it was race prepped already and the guy who wired it made it so just the kill switch was the only switch and i had to charge the battery every week  because they didn't wire it correctly. i did find where they screwed up and just put another switch on the bike. either one shut the bike off but the second one shut off all the power like the key switch would have.
so any way my 07 still has the key should i leave it or put in a switch?

Nope nothing wrong with leaving it on the bike.

Just don't forget the key at home or you will be hating yourself all weekend.

I have seen crashed bikes with the key broken off in the switch.

[danman67]

Yeah...that sucks too.

[Garywc]

i have thought of that happening i hope it doesn't  but if it does then i guess i will take the switch off then
