So the boiling gas issue reared it's head again this week (temps in the 90's for the first time). The smell from the boiling gas is so bad I have no choice but to leave the bike outside for 30-40 minutes. I've already done the reflective tape, and don't have the funds to do ceramic headers at the moment, so was wondering what those out there smarter than myself thought about putting a fuel safe shutoff valve on the fuel tank vent? (non-cali bike) Garage smelled like a bomb waiting to happen after yesterdays ride, so today I temporarily plugged the line and you can't even tell the bike is in the garage now (going by the smell). May be an option until a better fix comes along, just want to make sure I am not hurting anything. One thing to look out for would be leaving it closed while riding (as I'm sure it is probably bad to ride with the tank pressurized otherwise there wouldn't be a vent  ), to cure this I thought of clipping a red flag to the throttle as a reminder or something to that effect. Any thoughts? | ||

There's a lot of surface area on the inside of the tank. Any pressure can generate a force proportional to the surface area. A small psi and a large area is a large force. I would be very leery.... Z | ||

I wrapped my rear exhaust manifold up to the factory heat shield. This seems to have fixed my gas problem. I have put over 900 miles on it since the wrap job and no problems yet. | ||

I fill mine before I park it, no more fuel smell. | ||

Strange indeed...i had the bike up to 213 degrees last week. That's about as hot as I have seen and about as hot as I want to see...I popped the gas cap to see if it was pressurized. It wasn't at all. I listened for boiling. I heard a soft noise, but it would be hard to be considered boiling. I attributed it to something mechanical (fuel pump possibly). It COULD have been boiling, but it certainly was not vigorous and I saw no bubbles at the gas cap. Fumes...none other than the normal fumes one might get from an open gas cap. | ||

Trip to the dealer is most advised to the thread starter. Remove your plugs asap/return to stock prior to dropping off for diagnosing. Best of luck in your resolve. Please post your experience here for us all to understand and learn from. | ||

A trip to the dealer is planned, but the bike is my only means of transportation for the next couple weeks, so it won't be until then. I did mention it to them the last time the bike went in, they said they didn't have anything for me, but would let me know if Buell released anything as far as an update. Released the pressure on the tank just a bit ago, was about 8-10 seconds of air coming out, couldn't have been more than 3-4 psi. The smelling up the garage will also happen with out the gas boiling, so even if I do the wrap or the ceramic header, it still may not fix the problem. | ||

The California only bikes have a canister that the fumes deposit into, hence no smell. However, if the canister gets plugged up with gas (if the bike is overfilled), then it will be similar to a non-Cali bike with a plugged overflow tube. Consequently, for those of us with not Cali bikes we get the fuel smell. The next time your at the traffic light, look down on the right side of the bike and you'll see the gas fumes coming out of the overflow tube. It's especially visible when the sun is shinning on that side of the bike. This is what continues to happen once the bike is cooling down. | ||

On a hot day, especially one that started cool, you will get significant liquid and gas expansion. You have to plan your fuel level for your riding. The frame, aluminum, is a giant heat sink. The engine heats it from below, but the vent is up front where the cool, fresh air comes in. At first, if your level's down, you get gas venting. Because of the cool air at the neck, the gasses start to condense - right at the vent. Typically, the liquid you see will be condensate, not fuel. I put a fan on Loretta when I pull into the garage but I still fail to see/smell the issues some of you are having. I also leave the garage open for a half-hour or so after getting home. I have yet to smell anything more than a slight gas smell. Z |
