Thanks for the replies. I checked the cap and it is not an issue. Same with the cap off. It does flow but not as much as I would expect. The hose is is about a 1/4 full and stays about the same level while idling and I can see a consistent trickle,. It does drop a bit when I turn the throttle. Can't see when I am riding so I don't know what its doing. And when off road and loading it I don't know what the level is, I don't think its getting enough. The YZ petcock came to me damaged so I had to send it back..The box was crushed. I am still looking at it but have not been able to spend much time on it..

Hey. Lenny the Badger. Pass the toothpicks will ya? And whats with the fuggettaboutit? Did your Mama teach you to a speak like a dat? 

Drain the tank, pull the petcock off and shove a drill bit into the tubes in the tank… perhaps they are plugged up a bit?
