With a very low gas tank today the bike was repeatedly trying to stall out and each time I could head it off by cracking the gas cap. Dinqua and I had a date to put in some new needles and while the tank was off he determined the vent in the tank itself is plugged. A pipe cleaner wouldn't go very far in from the top due to the bend in the vent line and nothing was dislodging from underneath which could take more of the pipe cleaner. Dinqua thinks I may have a warranty tank on my hands as the vent line in the tank may not be cleanable without getting inside the tank.
