What're the yellow and green wires on the clutch perch for?

Clutch safety switch.

The safety switch along with a few others makes the starting safety circuit.  When operating correctly, the clutch safety switch prevents the bike from starting unless the clutch is pulled in, or the bike is in neutral.

thanks

No problemo.   

Where do i plug these wires in? (Don't think my last perch had them.)

I think you need to talk to Joshr08....

Joshr08 you there?

You can just hook the two clutch switch wires together and the bike will start if it's in neutral with sidestand down.  I plugged the two together inside the headlight housing on my 97 GS and eliminated the clutch safety switch.  That made it the same as my 4 Hondas before it were.  If the clutch switch is operational the clutch must be pulled to start even if the bike is in neutral when the sidestand is down.

Sweet What if i just clip em? Bike starts in neutral now without em...

The clutch switch is in series with the starter switch (button) so the starter shouldn't crank over when you push the button unless the two yellow/green wires are connected together by the clutch switch or by connecting them directly together to complete the circuit.  What year bike do you have.  Maybe someone has bypassed the clutch switch already on your bike.  If it works without connecting them you can just stuff them back into the headlight housing to get rid of them and they will be there if you need them later on.

Leave them alone, unless you want it.

Someone has already bypassed yours. It's the most common cause of "won't crank". So, do nothing (or just thread into headlight housing for tidy).

To actually use it, find the corresponding wires (same colors) inside the headlight housing, which will be plugged together with connectors that are just like the ones on your clutch switch - unplug from each other and plug in your switch.

Thanks guys i was thinking maybe it was something like that...
