storing upright - oil in airbox

[06Pred500]

Hello,
I've searched but cannot find an answer on this -
I have a 2006 Predator 500.
when I store it upright (standing it on its back wheels and wheelie bar) it collects tons of oil in the airbox from the crankcase breather tube.
I have never had this issue with any other quad.
is there something I'm doing wrong or ????

Thanks!

after looking at mine as i am new to the predators also. it is because of the location of the breather tube that is located on the clutch cover, only way i see to resolve your issue is to relocate the breather tube towards the front of the machine instead of going to the air box and use a little filter or seen some use a fuel filter and that would work fine and would fix your problem!!
