Grey Wire & Throtle stop

Must be good. Actually saw it mentioned in a Cycle World article about RW426 but no details. Sounded cool, now give me the scoop.

to quote Florida426:
The neutral switch in the YZ 400/426 is a remnant of the European spec models. They are sound tested rigorously over there and the test is done in neutral. The ignition mapping is set up to limit the revs in neutral so as to keep the maximum noise level down. We have them simply because it is not cost effective for Yamaha to leave them out for the U.S. / Canadian market (FP models.)
so, what happens when you disconnect it is that a bit more voltage will go to starting...

I can cut the wire and it'll give more starting voltage?
Will that affect the wiring in any way?
Like in neutral? What happens?
What happen to my lights?

Grey wire affects your ignition QUITE DRASTICALLY somewhere around 7K rpm. Several guys have found removing the grey wire has fixed a very difficult to eliminate carb glitch. It WAS the source of the problem.
The grey wire is found ONLY ON U.S. BIKES

My WR does not have a neutral light, If it does, I havnt found it yet. It was suggested or (maybe I understood)that the grey wire had to do with either ignition advance or rev limiter. Not sure. Is the grey wire under the tank and where exactly would I find it? Havnt probed around there much.

If I remember correctly the grey wire is paired with a black wire. There is a group of 8 to 10 wires coming out of the ignition box, the grey and black seperate theirselves from the other 6 or 8 wires. Pull it out and insulate it and you can come back at anytime and reconnect it.
Your throttle stop is screwed in the backside of the throttle cable wheel on the right hand side of the carb. You have to take off the plastic cover over the assembly. Remove the coil from the frame so you can get an allen wrench in there to unscrew it, I cut my bikes throttle stops down to 23mm but have heard others say anywhere from 21 to 25, this is the entire bolt.
Good luck, I know you'll like your bike even more with the newfound power.

You might try 3 Palms for some riding. It's about 15 miles north of Spring at the 1488 exit. They've got a couple of MX tracks if your into that type of riding.
Also, at the dead end of E.Hardy there's alot of riding on Spring Creek. We park at the guys property on the right after the toll road bridge. He's very fair on the price to park.
You should really watch out at the Nat'l forest. If your caught riding on the roads or the pipeline easements you can get a healthy ticket. I've seen the rangers videotape riders on the pipelines then come to the parking area and look for the riders.
Send me a PM sometime and we'll go riding. I'm in The Woodlands, right up the street from you guys. When the weathers good there's some great riding in the forest. If you don't have one, call the Raven district office of Sam Houston Nat'l Forest and get a map of the PMT's (permanently marked trails)
