so should i put some weight opposite to that then?
I have 404's and my valves also sit at the 6 o'clock position while on a stand. People here are essentially guessing at your wheel situation. Do not put a weight on a wheel that was never intended to run it.
Take them to a bike shop that deals with ZIPP and have them take a look at it. If they can't figure it out...then will send the wheel to ZIPP. Its totally possible that the rim itself could have some kind of manufacturer defect. If ZIPP finds nothing is wrong with the wheel...then its user error.
