I have recently bought a sled with a couple year old boon docker kit on it and I have herd a bit about a roll over valve that can be installed on the oil tank to let the tank breath but will not leak oil out if you find yourself rubber side up(not that that ever happens). I herd some guys are mounting the same kinda breather that is on dirt bike gas caps, they have a little check ball in them. I have also herd that these tanks are not meant to have a breather they are mean to leak some oil through the seals, which seems kinda odd, but not completely unrealistic.Can somebody shine some light on this either way, thanks much.
