ok, im new to this site so if this was already a thread my bad.
so my brother got his new 450r and he did this green wire mod that apparently makes the motor rev out to a higher rpm. then he said that i could to it to a 400ex, except that the wire was pink? please let me know if you actually can do this on a 400ex. and sorry again if i just reposted this. thanks.

no prob, if you are wanting to increase your rev limit get a rev box but it really doesnt do any good since the 400 does not create any power up that high in the rpm range. steve

yeah there is no wires to cut to make the ex any faster. the pink wire your friend mentioned is on a can am DS450. it releases a race curve in the timing and allows it to rev out without limit. i work for a can am shop and this is a common confusion, i have people ask me to do it to there outlander 800's and there ski doo sleds because there all made by can am. (BRP actually) but as far as i knew the ds was the only one you can do it to, i had no idea the honda 450 has a wire mod like that too.
