05 TTR 90 - Lost Key. How to bypass ign.
(Click here to view the original thread with full colors/images)

We lost our only key for the TTR 90. Have a trip planned for Ocotillo this weekend with all the kids.
Is it hard to bypass the ignitiion switch or am I going to have to take the walk of shame to the dealer?
Any help would be appreciated.
Thanks,

Should just need to jump the wires.

I have 4 wires to deal with. 1) Red 2) Brown 3) Black 4) Black with White stripe.
Which do I jump?

Get a few extra fuses. I believe you need to jump the red to the brown.

just unplug the black\white wire and your'e done. you may do that at the CDI.

Thanks. I will get some fuses and see what happens tonight.

I believe lucas is correct. By unpluging those wires you bypass the key switch's ability to ground out the ignition like the kill switch thus letting the bike start.

If its like the honda just unplug it.

Red wire switched on a 2 pole rocker with Brown wire. New 10amp fuse because of attempting to "jump" all 4 wires together. Both Black wires were taped off. Works well.
Thanks for all your help.
All is good.

I almost forgot, the Red wire and the Brown wire complete the circuit to allow the electric starter switch to excite. Once those 2 wires are "switched" or "jumped" it is as if the key was in the "on" position. The 2 black wires when connected are a kill switch. SO, when the stock key ignition switch is turned to the off position, the engine shuts off. Since I eliminated the key ignition switch and used only a rocker switch, the kill switch feature was not needed as the bike already has a handlebar mount kill switch. Because I didn't need the wires, I just taped them up.
