Default Re: Whats With My Gas Cap

BikeGuy 31,

The gas cap has an extended cylinder in its center, I am taking it that you are saying to drill a, "tiny hole", just into the surface of the cap, if I do this the cylinder that holds the pressurization spring, will not be effected correct ?

Do you have any idea why the pressurization cylinder assembly does not work well enough to prevent this evaporation in the first place ?

My guess, . . is that there is not enogh pressure on the rubber washer that seals it when it is turned tight ?
