My bike keeps cutting off???

Postby Dkb7475 » Sat Jul 03, 2010 2:29 am



I have an 1984 Honda Goldwing 1200 Interstate that my father just gave to me. Prior to him giving it to me we had everything checked out at the honda dealership, in which they stated that the bike was in Great condition. However, I discovered that as long as I don't fill the bike up with gas, it runs fine! But when I fill it up with gas, it will cut off on me before I can get a mile down the road, but the crazy thing is if I drain the gas out to about 1/4 a tank, it runs Great! I need to know if anyone can tell me how to fix this problem because it's really preventing me from taking it out on long trips! Is there something going on inside the gas tank that is causing my bike to do this??? Please help me...Thanks!!!

My guess is a clogged fuel cap vent. Try this: fill the tank, and ride it until the engine dies. Then, remove the gas cap and put it back on. See if the engine starts up normally. My guess is that it will.

My reasoning behind this: As the fuel is pumped out of the tank, no air can get in to replace it. When the tank is nearly empty, it contains mostly air. This air easily expands to fill the void, and a slight vacuum is created.

However, when the tank is nearly full, there is very little air in the tank. As the fuel is pumped out, this tiny bit of air has to expand greatly to replace the fuel, and a strong vacuum is created. Eventually the fuel pump can't overcome the vacuum, and the engine dies from fuel starvation.

If this is the case, you can:

- replace the gas cap with a new one
- try soaking it in solvent to clear the vents
- drill a very small hole in it

Thanks WingAdmin! I have another question though...Do you think that the Petcock has went bad? Someone told me that the Petcock could be the problem. What is it suppose to do or should I asked how could it cause my bike to stall out like that? Again, thanks for your help!!!

Nope, that's not the kind of symptoms a petcock problem would cause. I'd definitely look at the gas cap.
