Im working on a friends 03 kfx400 and he wants me to bypass the rev limiter for the reverse. Anyone know how I can do this?

 

The reverse rev limiter is a SAFETY feature. What if your friend's friend or family member who is a newbie and gets hurt going reverse too fast? Are you sure you want to do that for him?

 

yes, im quite sure I want to get rid of it for him. he is not mechanicly enclined but he has been riding for over 20 years, just like i have. I think he'll be able to handle it. we have thought about the safety of it and drcided that since all his kids have their own quads and arent allowed to ride his, there is no danger of it hurting any of them.

 

There are many threads here outlining how to do this on an 03 or 04. The 05 and 06 have a different cdi, so no positive answers on them. Do a search, you'll find them. They also have some on z 400 central, but it's the same.

 

it is an 03 so it should be possible to do. i have gone back over the last 35 pages of threads for the past 4 months or so, and can't find anythig explaing how to do it. any help here would be greatly apreciated.

 

i dunno if it is the same as the Brute, but i did away with the reverse limp and used the button for a horn (legal requirement to get highway plates here in MT).

to just get rid of the reverse limp (for a brute anyway) just connect the two wires going to the over ride switch together. the left handlebar wires have two brown wires going to the controlls. find the one that is not butt spliced to three other wires. find the yellow wire w/black stripe. cut/strip the yellow/black wire (the end coming from the main harness) and just strip 3/4" of the brown wire and solder the two together, then tape.
the 400 may have different colored wires or even a different system, but this works on my brute.

Heres
the old thread.

I also sent a PM

 

how fast u wanna go backwards???
i dont get it.....

 

I don't get people like you. It's not about going fast in reverse. It's about having the power you need sometimes. I know I can't stand having that rev limiter kick in with the throttle barely cracked.

 

I dont wann go fast backwards, but when you are reversing in mud or uphill and the tires will just barely turn, you go nowhere. thanks for all the help everyone, I really apreciate it.
