Last several start up's, the Three Wheeler had sat a bit and a slurp of oil got sucked into the air cleaner.

I would like to avoid this. I am assuming the oil is sucked up through the breather hose from the sump. If prior to starting I simply disconnected this breather line, or if I even added a shut off valve in the hose, I am assuming this would prevent this behavior? I don't see any issue doing this? Am I missing something, or is this a quick way to stop this and avoid having to drain the sump prior to starting after an extended sit with no negative effects?
