Did the grey wire but no difference???

15 posts in this topic

Ok so i did the grey wire mod on my wr 450, throttle stop was already done and it doesn't seem as though the bike has gained much more, if any, power. The bike has an fmf pipe on and was running fine before the mod. At first i thought it needed to be re jetted afterwards but the power is still smooth and isn't bogging down or anything. The only thing i can think of is to open the air box up a bit more and rejet but will this make a difference if the the bike is running ok now and not bogging down?

Thanks guys, Ross

I only noticed grey wire benifits in the over 8K RPM range. very noticiable on a long grade(hill).

on my 98 wr400 I had to pull the tank to get at the wire. You may be able to do it by removing the plastics

Yes you have to remove the tank but its very easy to do and you don't have to disconnect the fuel line. There's a good video on you tube wich shows you exactly wat you need to do and how to do it, just type in wr250 grey wire mod and you should be able to find it

Does anyone know if it's more noticeable on models '06 and older? Does it have the same impact on 07 and 08 models? Also, after having a bit of a search through out forums, i'm having trouble finding out if there are any risks or detrimental effects to the motor by doing the grey wire mod?

The grey wire mod should go hand in hand with the throttle stop. The wire was to alter the timing slightly at higher RPM to account for the reduced throttle opening. On the older ozzie and NZ models, they didn't have the long throttle stop or the grey wire, so to answer your last question, no it won't have any detrimental effects on the engine, that's how it's meant to run when you can twist the throttle all the way.

Thanks Alternative. I'll get into it tonight, as that's about the only thing I think i prefered on my WR426, which was a sensational bike. If you saw a corner coming up which was a few metres further than you expected, that beautiful motor would just keep making power to the rev limiter. You could just hold it on.

Having said that i love my 08. Just getting used to it that's all. Seems to flatten off a lot earlier.
