Gas cap breather installation

that why he vented it

My response was to wheel bender saying he has gas leaking on top of his tank... I guess I should have quoted it, but I didnt think anyone would think I was replying to the OP - as thats me.

Cool. i'm interestged in venting my cap that way. I hate the way fuel seeps out onto the tank when it is close to full.

I took a Hand drill and a drill bit the size of a pencil led and drilled a hole in the center of the cap....Took me 2 minutes if that and I have no problems with gas coming out or water getting in....The hole doesnt have to be any bigger than the amount of fuel being used by the engine....The size of jet is smaller than a pencil lead....

yeah, there is no need for anything fancy if the bike is stored indoors and is never ridden in the rain.

I get some gas that sloshes out. On my "eventually" list is getting a new cap so I can do a vent job more like the OP

How about doing like the lawn mower cap with a cardboard like washer with a offset hole to one side inside the cap? That should defer the splashing..........Curt

it might help, but what I know happens with mine is that gas sloshes up into the cap, gets trapped amongst the components of plastic, metal, rubber, and then bubbles out from there. It's not directly splashing out like if you were to run with a glass of water.

I know that is what is happening because the gas gets caught in the cap and inhibits the breathing-- not as bad as not having it vented at all. I have to drill another hole to make sure the gas that is getting caught up there will drain back out.

Oh, and I am using a Whizzer gas tank, not a stock Chinese tank, so the inside of the cap is more elaborate.
