Kayleigh Posted February 6, 2006 Report Share Posted February 6, 2006 i have a HONDA 400EX ....... was riding it today when it just shut off. when i tried to start it up it wouldn't stay on and once it did, when i rode it in 1st gear, it made popping noises and wouldnt run properly. checked the oil and it needs changing... could this be what's wrong?? the only reason i ask is its not gonna be changed for a while and i wanted to know if thats all i have to worry about.

87_shee Posted February 6, 2006 Report Share Posted February 6, 2006 I thought u had a 450r.?? Quote Link to comment Share on other sites More sharing options...
fastbanshee8 Posted February 6, 2006 Report Share Posted February 6, 2006 Sounds more like an ignition or fuel problem. Quote Link to comment Share on other sites More sharing options...
NotsafeFWD Posted February 6, 2006 Report Share Posted February 6, 2006 Yeah it sounds like is running a little too fat. I wonder if the choke might have been left on, or the plugs fouled, or maybe it was just plain breaking up. I thought you bought a 450R, like was stated earlier. Not that its really that big of a deal, just wondering. Quote Link to comment Share on other sites More sharing options...

I know it sounds stupid but this happend to my uncle's 4wheeler this past weekend. He's got a short short in his CDI box. May not be ur situation but worth a look.

tithead Posted February 6, 2006 Report Share Posted February 6, 2006 is the pop loud like a back fire or just a pop? Quote Link to comment Share on other sites More sharing options...
Kayleigh Posted February 6, 2006 Author Report Share Posted February 6, 2006 my quad doesnt really "pop" like its backfiring.....it just sorta "chugs and puffs along"....if that makes any sense. OKAY THE DEAL WITH THE 450 AND 400 THING.... i posted that i got a 450 because thats wat my dad had told me over the phone. in all actuality---it was a 400ex. felt pretty stupid since i had posted that i had a 450, but figured it wouldnt really matter if i "edited" it or not. so there ya go. i have a honda 400ex. thanks again for understanding that i'm still a rookie maybe i need an oil change...

Hilarious Posted February 6, 2006 Report Share Posted February 6, 2006 (edited) Will it rev up when in neutral? Or does it just bog down when in gear, with a load on it? If it wont rev out, while in neutral it may be a fuel or electrical problem. Like I said in my earlier post, that happened to my uncle's wheeler. It wouldnt rev out, tapped on the cdi and it came to life. I dont know what kind of little dummy sensors the hondas have on them. May be a rev limiter or some such shit on it givin you troubles.

Was the popping something in the transmission or was the motor popping as you revved it? Quote Link to comment Share on other sites More sharing options...
