Gray wire?????

I need some more help here, what is all this gray wire b/s about??? Does it change the ignition mapping to perform more like a YZ?? and how the hell do I find the wire on a 2001 WR426?

thanks in advance,


Ronin, do a search on Grey wire. This has been discussed, tested, implemented by just about every WR owner on this site. There is even picture of the Grey wire, from YamaCasi on file. Find it, cut it, your bike will be a new beast.

take your seat off, can't miss it!

i cant seem to find any info on the gray wire for my WR426. Also, under the seat is only the wiring for the tail light. Please help me.



Try searching "grey" and "gray" wire, it's there.
