Hi, I just did the grey wire on my 02 wr426 w a headlight switch so I can go back and forth. My buddy has a 98 wr400 and asked me if his bike could be done, Im actually not sure! Does it work with the older wr 400s too? thanks!!!

Yes, you can do the "gray wire" mod on a '98 WR400. I'm not sure if it is in the same location as yours though.

Hey "pbgunrunner1"...did you find a major performance difference after you did the grey wire??

I'm not sure if it was such a big deal on the pre '05 bikes...I have an '04 (Canadian model which may not have the US EPA restrictions built in) with grey wire still connected and I have no problem getting the front end to lift or with power in general....so it would be great to have your feedback.

I havent played with it much yet, but it seems like it has a bit harder hit in the mid range... Ill know more when I switch between them. On a side note- can/should that be done on the fly or w a dead engine only?

With the engine off to change mapping, if you do it when the bike is running nothing will happen.
