Glad I could help. That's good to hear

I was looking for this mod since a long time.

Got it done yesterday and it's great!

Thanks hornetgod13!

I did this mod tonight and it worked great. I would get mad everytime I stalled it in reverse and try to start it.. no more worries. Favorite mod yet!!!

Haha ya that's fast. But wierd tho. My rm 125 1991 does 65-70 and my 96 300ex does about 60-65 maybe 70. Ima test that against my friends snowmobile cuz it has a speedo. I was going to try the mod on mine but since it has electric cutout I prob. Cuz as fast as I want to go in reverse, I also want to be able to go in drive.

i just looked on my thee 300 ex on the cdi box ur talking about i think its the aftermarket rev boxes you get right? i foiund a black wire with a white stripe. is that wat u are talking about

I have a 2007 TRX400ex. I am looking for the plug on the CDI to find this option and cut that freaking wire. When i look at the CDI under the hood i have 4 different connector with 4 wires in each of them. Sounds like they changed something in 07 since i don't have the 2 and 4 wire plugs on my CDI. Can anyone help? It totally sucks to be on a trail in the desert rocks and have to play the REV. game on this thing.

If I was anybody who wanted to do this don't because it will screw everything up!

88 mph !! Did you drive it off a cliff?

my buddy and i both have 400exs and mine an 08 and his an 05 we both did this mod the same day last week oneday and today we were ridin and his quad stalled and would only start and run with the choke fully on just out of curiosity we hooked the reverse wire back up and it was fine but mine hasnt done any wierd **** like that yet. by the way both quads have stock wiring no rev boxes or anything like that Its definatly a cool mod but its not if its not gonna work i will post up if my 08 does it. Good luck to anyone else that does this mod.
