The manual also states that re-indexing the WR cam to YZ cam will cause the electric start to fail and may become harder to start. Keep in mind that the auto-decompression function is inherently timed with the cam, and that changing the cam timing will also change the auto-decompression timing. Without the decompression lever, as found on earlier models, this could make starting hard or even painful. If you want easy electric starting you and you want the YZ timing, you will likely have to buy a new cam.
Eihter way you should be able to get your local Yamaha Dealer to let your look at the manual.
PS. If you go for the YZ cam and want to get ride of the WR cam, PM me and lets see what we can work out.

Sorry, After reading all material I still didn't catch what the gray wire cut will generate to the WR 450 2004.
Is this a RPM kind of control ?
What do I loose (or win) ? How safe it is ?
I run long rallyes in far places, so speed and reliability must go together in my case.
Thank you in advance !

That way you can ride it and see what you think. If you don't like it or see any performance change, you can reconnect with no problem.
If you check the site "www.thumperfaq.com" you should be able to find more grey wire information. Check this link for more info and a graph of the spark advance curve with and without the grey wire. grey wire info.
PS. I'm not sure how much value disconnecting the grey is with out the throttle stop mod, and maybe the YZ cam.
