OK, I'm a relative newby. Have not ridden in 8 years, last bike was a 1998 CR 250, raced desert for 2 seasons. I'm now on a new to me 2006 WR 450. I've read all the modification posts, but stumped with the grey wire mod. I've taken off the tank several times now and cannot find anywire that is grey anywhere near the CDI box. I cannot reach the previous owner to ask. Seems like the wire would either be tucked in disconnected or cut...What might I be missing? This is my 1st 4 stroke, so not sure what to compare the power band to, but seems a bit sluggish. Any suggestions are greatly appreciated.
