What org are you racing with? I've never seen a racing org so far that does not require a full race belly pan that can hold at least a liter of oil or more. I'm pretty certain no stock "belly pan", aka lower side fairings, is allowed in racing for any typical sport bike. I would you do yourself a favor and buy a set of race fairings. For about $150 savings....it's not worth it. I don't think I've ever seen anyone actually race with a bike that had stock fairings on. I also know of a guy who had a set of chinese street fairings on his zx6r, with headlights and tail lights removed and when he took it out on track, the front fairing snapped because of all the air drag going through the headlight holes and a piece of it jammed between his brake lever and hand grip and at the end of the straightaway he couldn't brake anymore because the lever was stuck and crashed in the gravel. Save a 100 bucks now....pay a few thousand later.
