Help! On side of road and gas coming up from under gas cap

[Phishhead61]

Update: it was the vent hose. I'll explain more when I get to the motel.

 

Update: so I thought it was probably the vent hose, but I didn't bring my hex set with me. The vent on my bike is under a chrome cover that surrounds the tank mounted speedo. It's held on with 3 hex bolts.

 

Long story short, I waited for about an hour until it was completely cooled down and rode it back to the gas station I had bought the gas at. The mechanic there took off the chrome cover and low and behold I couldn't blow through the vent hose. He gave me a piece of hose and I put it on and tucked in in out of the way and was on my way.

 

My guess is I pinched that hose or someone that called me suggested the gas stirred up something that clogged it.

 

Thanks to the several people that called me! Great people on this site!

 

 

The title says it all.

 

I was on the highway for about 45 minutes, got off on a back road, road about 10 minutes and stopped to fill up.

 

I didn't over fill it and even if I did, enough has poured out that it shouldn't be an issue.

 

Got a half mile down the road and had gas coming up from under the gas cap. Stopped an took the cap off and the level in the tank rose up and poured out and then went down and it bubbled like air was being released, then it rose up again. It did this 2 or 3 more times and the I shut off the gas petcock and it stopped. I got back on and got 50ft down the road and it did it again. Went through the whole thing again. When it stopped I tried to ride it again and I got about another 50ft down the road again and gas came pouring out From under the gas cap again.

 

I'm looking for answers in the tech area, but can't seem to find any thing. I have limited tools, but there are some houses around.

 

I'm riding a 98 Royal Star Boulevard.

 

Thanks,

Rich

sounds like you may have a plugged tank vent. I'm not sure on your model but most bikes have a steel tube on the tank and rubber hose from that to extend the vented fumes to the atmosphere. Take it off and blow through it as it probably has a bug nest in it

The 2nd gen would get a clogged hose. Bugs or daubers just plug up and no vent then it has to vent somewhere and the seal on cap is next.
