my 400ex wont start it sounds like its tryin but it fire all the way up anyone have any ideas to get it running again

 

Hey sandman I have the same problem! I have no idea what to do she will not fire for anything, even tried pull starting it, i think something is wrong electronically..

 

If you haven't ridden it for awhile, make sure your battery is fully charged. Had to jump mine last week to get it to fire. Battery turned it over but wouldn't fire it.

 

take the airfilter off and squirt some starting fluid (ether) in the carb while cranking. That crap will start.

 

last time this happend i pulled it around my block for 20 mins then it finaly started up but i dont wanna do that again cuz i dunno if thats bad for it or not

 

cmon ppl i need some advise i dunno what today and i wanna go riding soon

 

did u try ether, spray some of that in the air box, dont use it all the time, cuz yur quad will get addicted to it like crack, it wont want to start at all unless u give it a shot of ether.

 

NO dont use starting fluid, its not good for the bike. How cold is it? CHeck your plug? IF it is pretty cold out I usulally hit my throttle once with the choke and it will get close to starting. One time I fouled a plug also, it always sounded it wanted to start but never did. Changed the plug and it started. If you have no power to anything check the fuse. It is around the battery and solenoid.

 

its pretty damn cold and i think its the spark plug too im gonna go get a new one tomorrow i think and with the new sparkplug
it better fire and if it doesnt i dunno what im gonna do

 

Ok i had this prob. Get a new spark plug, turn on ur choke all the way, don't touch the throttle until it starts to start then u can give it gas. Just make sure u don't touch the throttle while or before u're trying to get it to turn over!!!! It will foul your plug and flood the engine. Once u foul ur plug they won't start unless u're d@mn lucky!!!
