Grey Wire

7 posts in this topic

I am seeking optimal performance for my WR426 2001. I read below that someone suggested disconnecting a so called "grey wire".

Can someone tell me what the function of the Grey Wire is, where is it located (best disconnection spot), can it cause any damage? Tks!

grey (gray) wire is apparently only on the U.S. bikes. It screws up the ignition timing to meet U.S. emission (or noise?) standards.

Use "Search" for the grey wire.

If your WR is a non-US model - forget it.

The grey wire is for detunign the US models only.

PyroTed, see the double connector? 1 black/white wire & one grey wire-that looks white in this picture, closest to the blue frame. Cut or remove the grey wire from the connector, insulate w/ elect tape, you are set. Now go roost!!!!!!!
