Ok guys...help me out on this one. I have a 2000 warrior that all of a sudden dies out when you try to give it more than 1/4 throttle. It starts fine, idles fine, but when you try to give it throttle, it just dies. I took the carb off yesterday, cleaned it out, and put a new plug in. It ran perfectly fine all day long, then at the end of the day, it magically started doing this again. Is it a fuel or spark problem? The emergency brake is fully DISENGAGED, so I know it's not that. But like I said....if you try to hammer the throttle, it just chokes out and dies. If you slowly ease into the throttle, it gets to a point to where it starts backfiring through the exhaust. any clues????

 

Parking break is on.

 

ya i know you said its unplugged but im going to agree with JakalWarrior its still you e-brake...if its just unplugged, rip the plug in out and seperate the medal connections, tape each wire up seperatly..make the 2 wires that plug in seperate...and that should fix it

 

Yeah it dont matter if they are disengaged, before I removed mine you could look at it wrong and it would come on.

 

400ex's do that when they are out of gas do u have a FULL tank if not then fill it up then see how it goes

 

Where is this sensor located and how do I unplug it? I've never messed with it.

 

mine was doing that too untill i cleaned the carb....

 

The sensor is one of the 3 black plugins on your e-brake housing..i think its the bottom one of the 2...just rip the socket off the wires and tape the wires up seperatly
