yes is the simple answer. it shouldn't happen very regularly but it will happen on occasions. My bike normally does it for about 15 minutes after refuelling.

all it is, is the fuel/air mixture running slightly lean, so not all the fuel is burnt before reaching the exhaust pipe, then when it hits the air going through the exhaust, it basically explodes, causing the popping backfire

if you're concerned about it at all then take it to a garage and have them look over it. it may need the carbs rejetted, or the air induction/airbox seen to but all in all there's generally no issue. most people love the backfiring sound (me included :))
