WR 450 CDI mod

I was talking to a guy that owns a 04 wr 450 and he said that he did a modification where he did something to the CDI and it made the bike run like a YZ. just wondering if anyone has herd off this and can explain it to me in more depth??


I have a feeling they were talking about the "Grey Wire" mod, and not the actual CDI itself.

I have never heard of a CDI "mod" other then replacing it, but maybe someone else has.

Yeah, it is the grey wire mod. Nothing else you can do to the OEM CDI.

i think it is the gray wire mod. how does it work?

I didnt fell any differance
