gas coming out air cleaner

[brian9094]

2016 k9 124cid super G carb I changed the intermediate from #31 to #33 runs good in low rpm I also changed main jet from #76 to #80 and now blowing gas out carb on full throttle help!!!

Why did you change them in the first place? What was it doing?

You have more gas than air flow.... 80 is too big....

"and now blowing gas out carb on full throttle help!!!"
For every action.... fill in the rest.

 

[Brew]

Yeah, jetted too high! 31 and 78 is good!

will not get up and run I am thinking heavy breather more air

 

[brian9094]

31 and 78 seems just perfect and I've upgraded exhaust and air cleaner maybe your main is to big

I am thinking heavy breather more air other then the SS tear drop that came with it going to try the 78 main for now

Regardless of the jetting, gas really shouldn't be coming out of the air cleaner. You mention "under full throttle" so your obviously moving. I would venture to say that it's an air cleaner design flaw that is creating a siphon effect. It's no different than not blocking the back of a hood scoop off. It will siphon the fuel out as air passes over the air horn.

Exactly! I, stupidly once, tried to ride with a fountain pop sitting in my fork bag. BAD IDEA!! The faster I went, the more pop got pulled up and outta the straw. (had the stickiest shirt and pants crotch ya ever seen) I'm thinkin you are right about the siphon thing!

I agree gas should not be coming out of the air cleaner.

Very possible, but I can't help but notice that there is no complaint of this specific issue before Brian9094 changed the jets. However, there could be a design flaw which is made worse by the increased fuel ratio therefore causing this. Or simply too big of jetting.

Brian9094 let us know how the #78 does.

[Marky-Marc]

Is it broke in yet? Brand new bike with a 124 and a G carb and you jetted it....may I ask why????

 

[Marky-Marc]

But, most are correct on a stuck float......jetting aside....

 

[Marky-Marc]

Why does the float get stuck only at higher rpm? Jetted too big.....
