from the 250F FAQ (99% of which applies to the 426/450F's) sitemap,
Seems like you could put in line a simple on /off switch. Maybe like your headlight switch. Then you tell If the Mod changes any thing! I have yet to do it!
as you can see from that last link, there is a definite change to he midrange iginition map with the grey wire disconnected. moreover, from testing we discovered that the grey wire is ONLY interrogated when the bike is started; therefore, putting a switch in the circuit is of little value if you expect to be able to toggle between ignition maps while riding. you have to stop the engine, and restart it in order to change to the other ignition map.

the problem is your accelerator pump (AP). see
It seems to help with some of the low end bog I was getting.
and these three threads:

I did the switch on my old WR426 and didnt feel a bit of difference. My new 450 is a Canadian and in 04, they didnt have the grey wires, so mine is "YZ"'d in that area I guess.
Put a switch in line to turn on an off. From what I understand the yz is not grounded an the WR is grounded. That is what changes the CDI mapping.

Waaaay too much of a pain to go from "running good" to "runs like crap"
Oh... the "pink" wire mod is for the CRF.

i want to do this to my WR450 05 but will it damage my engine? i don't want it to stuff up by doing this. has anyone had any problems. is the different timing going to cause any issues or cause valves need more frequent checking? can you do something to alternate between the two maps via a switch?
Just about everyone with a WR does this mod? No, it doesn't mess up anything. Just do it and move on!! If for some reason you don't like it connect it back up. It's really no big deal.
