After extensive work ill say a lil smoke( witch can seem like a lot) is normal. as long as your oil light stays off your ok, even if you are leaking like a sive. just keep the kill switch covered in case the light pops on!
I had a leak a 1/2 mile from home. I covered the clutch and kill and kept going. the light poped on 30 ft. from my drive way and i was on the clutch and kill instantly. It ended up that my drain plug had come loose and fell out . The bike took 2 min. to drain all the oil while runing before the losing preasure and kicking on the light . I got a new plug and oil and kept on going!! No damage or problems (other than a well lubed rear tire, like being on ice). So you should be fine to run it for a while and see if the smoke starts to clear.
