my Gas Cap sucks!!!!

[srreynolds2003]

Ok guys help me think....I really don't like the design of the gas cap. I dropped my bike the other day and I lost about 1/2 of my gas before I could get it up righted again. The cap stayed on, but fuel still poured out of it.....am I the only one with this problem? Do I need to get a new cap.
My cap does not Screw on.

I have thought about a few of ideas....do any of these sound possible?

1. Screw a thin Round Rubber/Plastic Disk the same siaze as the fill hole to the Bottom of the Gas cap. So it would act like a stop/flap inside the tank when the bike is laided over...

2. JB weld the a screw type fill over the existing Gas fill....Possibly cut one out of an old plastic tank and attached to my tank over the old fill?

3. Get a Tank from an old XR200. Is there a specific year that will attach to our bikes?

4. Will a Tank from a Chinese Dirt bike fit. The type with the screw cap?

This all concerns me, because in the next few months I plan on doing some Enduro/Trail type riding, I am sure I will drop my bike at some point, and I do not want to be there trying to pick my bike up, while it is pouring gas on the ground....
