Hi Guys. I have definitely determined that the breather tube on my bike was pinched closed directly beneath the fuel tank. I probably have the hose incorrectly routed, and I am going to send a picture to Doc for his thoughts (because I have his email address, and I don't know how to upload pictures to this site and it's too late tonight to learn how). I did some tests by blowing air into the fuel tank through the filler cap, and when I disconnected the breather hose air flowed, but when I reattached the hose and lowered the tank air would not flow. I was able to force the hose into a position so that it would not be pinched when I lowered the tank, but I don't think I have the hose routed properly. I think that when I reassembled all of the air box pieces I removed to get at the IACV I should have routed the breather tube differently - I did not remove the breather tube from the bike. If someone could post a picture showing the correct breather tube routing beneath the tank (by lifting the rear of the tank just far enough to see the tube) I would really, really appreciate it.
