my yfz is f*cked up rite now. i dont know whats wrong with it..keeps leaking gasoline and makes a noise like theres fuel over-flow.. (i dont have a mix just 91 or higher)and its shutting off after a minute or so..changed the spark plug..battery..c-shaft..jets and the fuel line are fine..i dont know? damn it..i went for a ride last week,when we got that yama-ha-ha(yeah i believe yamahas are sh*t but i still like'em)to run..and then i had to push it for like 4 blocks back to the garage..lol..what a workout LOL..maybe someone can give me some suggestions as to what the hellz wrong wit it..?


help me please..anyone/mechanics in the chicago - land area..

...i'll pay ya 2 fix it.....

thankxxxx

 

have you wrecked it, flipped it at all? i had a '05 and had a pretty bad spill on it. i had some of hte same problems and couldnt find out what was wrong w/ it. it ended up being the carb. the needle was stuck up in the seat. my quad wouldnt seem to start. when i DID....which was hardly ever, it would run for a FEW seconds then shut right back off. i hope this was SOME help to you.

 

Definetly check the needle, or check the float, clean the carb, get all crap out of there.

 

yeah i flipped it a couple times...i kept on doin' wheelies...i have checked the carb AND cleaned it..thats why im puzzled as to what the heck is still wrong with it..any other possible suggestions..?

 

Hmmmmmmm, im not to mechanical. so im stumped! my only guess is the carb. and you said you ruled that out, so idk. i hope you get it fixed though, and its nothing major.

 

SEE its driving me insane..i was sure it was the jetting..but NO! i almost get mad just thinking about it..cuz its the 1st time ever something like this has happened to me....makes me saY "YAMA- HA..HA.." EVERY time..piece of Sh^it....

 

anything electrical?

 

cant be...i put-in a new spark plug and battery..check all the wireing..and now im ..??????????? mad? lol

 

well ****! im stumped, lol. i would assume carb or electrical, and you've checked them all.

 

yeah and from all the thinkin and plucking i've done to the quad..im gonna loose my hair soon lol j/k

 

sounds like your floats are stuck. pull the bowl of the bottom of the card...take the floats out and the needle set...clean everything up real good. take all the jets out and make sure you can see through them. blow some compressed air through all the ports and make sure you soak it all good with carb cleaner. If gas is just pissing out of it usually its due to a float stuck open. Your bowl is filling up with too much fuel then its pissing out the overflow.

 

or your float level is wrong, check the float make sure it still floats may have a pin hole....I'd say it could be the float level which service manual can tell you the exact measurement it is suposed to be...check the float needle has a little rubber tip make sure it is clean...hope this helps ya...

 

youre awesome..
LOVE YA!
...im gonna take it apart again...hope youre right..

 

thanks thats pretty much what i was getting at...i'm a little slow with my wording this morning lol

 

definitly sounds like a carb problem,do you have a service manual?

 

nope...i did but dont even ask where its at...if i only knew..haha..

 

have u taken the jet out and blew an air compressor trough it mine had that problem too jus try things ppl tell u dont take it somewhere thell charge u alot and still not fix it

 

I think this is a carb problem, you need to get the carb properly cleaned & blown out, then check the engine oil cuz sometimes when you have an overflow problem gas goes into the oil through the cilinders which could cuz you mo problems.

 

EXACT same thing I told her in the other forum. Those bikes are notorious for that float needle gumming up and sticking causing the float to become stuck which in turn causes gas to pour from the overflow. Reason I know is because I have 2 of them.

 

Cracked Float or Bent needle
