Leaky gas cap

[Phaseman]

Any advice?

I have a leaky gas cap and I can see that you can disassemble it. Anyone know where to find a new rubber piece, or will I have to replace the whole cap?

Suzuki pn 85413-70000 should fix you up

Thanks SqDancerLynn1

I checked out www.cmsnl.com and saw the gasket you are referring to. It shows on a different style cap for a smaller cc bike. When I search that site for a GS1000e, the fiche shows a one piece cap assembl and no gasket as a separate part.

Do you know if I can disassemble mine and use the part # you have to replace the existing one on mine?

The part number for my gas cap is 4420049810

Make one out of fuel resistant rubber.

The gasket in these caps (the later sort-of-rectangular style) is not just a flat donut of rubber -- it's sort of a hat shape, with a metal reinforcing ring inside.


There are two solutions:

1) Don't fill your gas tank so %$#@! full. In hot weather, this will lead to a crotch full of hot gasoline no matter how good your gas cap is. (Shortly after you fill your tank with cool gas from the underground tanks, it will expand and overflow as it heats up. Someone does this at every GS rally for some reason.)

2) Buy a new gas cap. If you get one from Suzuki (about $45-$50), you can transplant the guts of the old lock so you can keep the same key. (The new gas cap comes with its own new key.)

You can also get an aftermarket gas cap with key here for $27.

It's unknown whether this one is a close enough copy to transplant the lock guts.

I used one on my 79GS850 worked fine, should work on your 1000 too...
Caps are shaped different, but the filler hole is the same size
