Small Problem

[WALLACE84]

Ok, everytime I go ride, after awhile the gas will start overflowing from the gas cap vent and go everywhere. I put a different gas cap on it to see if that was it and it still did it. I dont know what else would cause it. Any ideas? im just sick of having gas go everywhere on my shee. Thanks

Is it a stock cap Does it still have a long hose or are you useing a aftermarket vent? Is it leaking at the tank or out the hose?

[WALLACE84]

Its a stock gas cap with a long clear hose. Its leaking bad out of the hose after the shee gets warmed up

Id say throw the stocker away and get a tusk one from rockymountainatv.com there only like 20 bucks i believe. The stock one sounds like the vent is stuck open.

Yea, thats probley what I will end up doing. Even after I changed them with another stocker, it still did it :shrug:

that is a very odd problem, your obviously building up pressure in your fuel tank and the only thing i could come up with that would even come close to making sense because you've swapped caps would be that you have a broken reed and instead of blowing back out of the air filters it's building pressure in the carbs and back flowing into the tank through the petcock but that makes no sense either cause the way i see it you'd be dumping fuel from the overflows like mad before it started blowing out of the vent tube on your gas cap. if the vent is working on your cap it should keep any pressure from building up in your tank and since you can see fuel flowing from your vent it would stand to reason that the vents at least open...wierd...

I agree with you. It is a wierd ass problem. It only happens when the bike gets warmed up too. I guess I will just have to get a billet gas cap :biggrin:

This sounds very odd.

You sure it's not coolant leaking out from the overflow?

 

If your gas tank is pumping gas up and out, I don't think billet or aftermarket is going to fix that problem.

That's crazy, might be due to heat causing fuel to evaporate and then condensate when the fumes get to the cooler vent line, but still it shouldn't be much if any. Mine spits a little here and there but that's flogging the piss out of it, and granted the radiator is right in front of the tank. Maybe try one of those little plastic in-line check valves some dirt bikes have on 'em...
