been out in 95+ days and haven't noticed anything, but i do believe my bike consumes way too much gas

Its not been any warmer than 70 degrees F. Ive never noticed it dripping while riding. I run 88 or 90 octane.
I left it in the shop where I work for a few days, doesnt get below 50. I set a ratio right under the vent hose and checked it daily...no drips. Seems to only be when it sits directly in the sunlight so maybe it is normal?

Its normal. If tank had no vents your tank would expand and you would get bumps on the tank pushed from the inside out. Happens on hot days, usually after filling the tank. When the bike is on its stand its leaning over and takes less gas in the tank to do this. As someone else mentioned the gas goes thru the overflow in the filler pipe and drips down the overflow hose. Now for guys in Cali the vent goes to a charcoal cannister and it gets fed back to the motor while riding. I think it works with the AIS plumbing.
