I'm going to have it in to the dealer in a couple of weeks for some warranty work on my front master cylinder, I'll have them take a look at it then, in the mean time I checked the vent tube and it does not appear to be pinched, I followed it all the way from the gas tank to the cannister it connects to beneath the frame. I'm thinking about disconnecting it where it plugs into the tip over valve, as a temp fix.
