Revolver, good on you for getting out there and having a crack. It's great fun. Traction must have been very good. Don't bother doing a burnout and don't let your tyre pressure down either. If you're wheelstanding too much then you have too much traction or you need to ride the clutch a bit more. As for the coughing and farting...I expect your diagnosis is correct,,,water doesn't combust!
