Should I unplug my grey wire or leave it? I tried to search before asking this question with no luck. Can any one help, and why? Thanks.

If you do the throttle stop, you need to do the grey wire also as that allows the bike's timing to compensate for the increased fuel. Without it, you're kind of negating the benefit of the unrestricted throttle...SC

Unplug it and do the other free mods and your bike will transform into a fire-breathing dragon!

I've read lots of threads on this subject. I know that the wire causes the timing to retard (12 or 14 degrees I think) after 1/2 throttle to help keep the noise down.

Then I read one thread saying that with the wire disconnected to be careful because the rev limiter no longer works.

Can anyone confirm for sure if this is true? :banghead:

Cutting the gray wire does NOT affect the rev limiter...

Another confirmation here on the rev limiter myth. Although, in some cases it has caused the bike to transport the rider to the magical land of Narnia where they are crowned Queen of the Sugarplum Fairies in the castle of the Gumdrop Forrest...I love old wive's tales, don't you :banghead: ...SC

I also read where the grey wire is only a feature on US bikes. Can anyone confirm if my Australian 2001 WR400 has a grey wire that needs cutting?

Yah, 04 WR Kali model.

Under the tank, 6 pin socket-pull it apart. The gray wire is in the center location in the socket assembly. Use a paper clip to realease the terminal, fold it back and taped it up. :banghead:

I'v heard from an australian that your wr and also the european models have yzf mapping without cutting the gray wire but I'm not sure. On my year 2004 the gray wire is connected to the cdi unit but I havent "followed" it til the other end so I dont know if its connected to ground or not :banghead:

If anybody know for sure please let us know.
