Default Tank not venting

I've noticed the last few times I park after riding, my yank is building with pressure, I have to pop the cap to relieve it. Is it just a simple wire poke to fix that? Makes me wonder why it's plugged. Since I had to seal the tank due to excessive rust when I first got the bike, I'm wondering if my sealer is degrading and floating loose. Sad thought, but like I was told, it's just a matter of time before it.........

Hmm, good question. I think it is a vented cap, at least it looks just like the vented caps for cars I've always seen. Maybe I just need a new cap if I can find one.

Did you seal it with that cap on? If so you sealed the vent.

No, I didn't, but that was a long time ago and I would have noticed. I just looked at the cap, and it looks fine. The little spring loaded vent pushes in and springs back out. I can't imagine what I never noticed it before, but maybe it's been hissing forever. I was just wondering about that little hose fixture that sticks out of the tank there. Never new what it was for. Maybe I'm just looking for a reason to complain.

Since you live in Florida, I'm not sure if this applies. But I had a similar problem with my Heritage that I purchased in Calif. Ended up the charcoal canister that the tank vents to was plugged. I just disconnected the vent tube from the canister and let it hang open. Problem solved.

No cannister on this old boat, must have been a California thing you had. Thanks.

If the sealer is degrading and loose I would think the motor would stalling or sputtering too.
