carb problem fuel spills out

[v8killaz]

ok heres the problem
i had the machine sitting for some time but whenever i let it sit for so long it gets this same problem. The feul is off, then when i turn the fuel to on the fuel just keeps spilling out the bottom of the carb through the tube, I can start the bike and run it but then it starts spilling out too fast and the bike shhuts off

I cleaned the carbs and it helped it, stopped the problem but then it happens again when it sits for some time.
only when i turn the fuel on or to reserved. ive had it running and finr for a long time but this happens and im lost on carb related stuff ha

any help will be appreciated.
My though was the carb gets overflowed with feul thats not needed.

if u look at this diagram
Mt Holly Powersports your Premier Yamaha and Honda Full Service Dealership in the Delaware Valley

the fuel comes out of pipes number 15 and 12.

yes, you need to pull the float and look at the needle, make sure that there is no dirt or anything on it, and that there are no marks in it, also you need to check your float height. its either that or your float is sticking

my guess is that the float needle is dirty and sticking take the carb apart and give it a good cleaning

like i said guys i cleaned out the carbs pretty good with a brush and carb cleaner

maybe the float is stuck ill check aGAIN soon

today i took the carbs out and the float was working properly closing the fuel flow when it raised and it was moving up and down freely

still have no clue what it could be. I started it up today and no sign of the leaking again. but it usually happens when i store it and then turn the fuel percock on it just starts to flow out then.

stuck float, wore needle seat, check the float hight, plus there a ruber o ring seal inside around need seat houseing u would check too.

what carb are u running too if i may ask??

 

[v8killaz]

like i said above ive checked the float and its working properly, ive check for leaks in it and it wasnt leaking moved freely. its a stock carb not after market

now that i dont turn the fuel off it never runs splills out its fine now rode it a few times and doesn spill. only happoens when i turn the fuel off and then after a period of time turn it on it just flows out

its prob. just drying up in there when you leave it for any amount of time, then the needle isnt closing all the way, prob worn out or the needle seat is worn out....

Try tapping the bottom of the bowl with a screwdriver handle very lightly next time its leaking and see if it un sticks then....


You can get a whole rebuild kit with everything you need to redo the carb the right way (including needle and seat and gaskets, orings etc...) on ebay for $11 to fix it the right way!!

my mikuni 26mm roundslide does this with the LT80... slide and needle both have scratches so I'm gonna try a stock one and see what happens toward the weekend...
