Motorcycle fuel tank collapse-- does this happen often? |
So it was 109 degrees today and my bike was in the sun... then I drove home to where it was only 70... later I went out to ride to school and my motorcycle's tank was crushed on the top, as if some great weight was put on it-- I removed the gas cap and heard a loud "whoosh" of air rushing into the tank.. apparently the tank was under vacuum after cooling off. Now I have a degree in physics and understand why the tank got crushed because of the difference in air pressure, but isn't there supposed to be some kind of built-in safeguard against this sort of thing in modern motorcycles? Mine is a 2000 Yamaha V-star 650. So if it is a problem with the motorcycle, what is it exactly, so I know what to tell the repair guy? Thanks! Clogged vent. Wow, yeah your gas cap should vent for this reason. I'd say something is wrong with your fuel tank cap. ask first if there is any recall problem on that make and model your story is strange i never heard any thing like it. This the first time I heard. Normally the fuel tank is strong. You can even sit on it. The little weight on the fuel shouldn't at all effect the fuel tank. There must be something wrong with the screw fixing the fuel tank. As you said there's a loud "whoosh" of air rushing into the tank. The tank must be leaking and rottan at the holder of the tank or underneath of the the fuel tank.. Check to it. Normally the fuel tank is very strong. In any accident, the motorcycle smash totally, the fuel tank will always at the motor bike. There must be something wrong with the fixing of the fuel tank. Fuel tank fillng cap has a hole. It is blocked. I think your bike has an electric fuel pump. It sounds like the fuel tank vent is clogged. The pressure crushed your tank. It happens with fuel injected cars all the time. This is the first time I heard about it on a bike. |
