Gas sloshes out of Coleman Mini Bike

[stuckmotor]

I have the Coleman CT200UEX off road minibike and really like it. HOWEVER it has a wide filler hole on the gas tank. As near as I can tell whether gas sloshes out of the tank or not, depends on the rubber gasket between the cap and the tank. Mine seldom seals. If anyone else has had this problem and been able to solve it, please tell me how.
Thanks,
Stuck

I would contact Coleman. Sounds like it needs a new cap. There are a couple of replies on the review page at TS with email contacts. One from 4 days ago listed a steven@colepow.com

Tractorguy,
Thanks for your response. Coleman has had their chance but I might give them a call.
On things like that I think back to the 77 Pinto that I kept taking back to the dealer with a leaky sunroof. After too many non-repairs by Ford, I peeled back the headliner, and reattached the drain hose "adding a hose clamp" and solving the problem.
