I really don't think your fuel pump is the issue. I've lost the fuel pump several times on my F4, and it never results in smoke. Additionally, as Phil said, the pumps are very low pressure on carbureted motorcycles... it's very unlikely that you're getting enough pressure to run the bike at low rpms, but not at high. You would either have fuel in the bowls at any rpm, or not. Whenever my pump goes out (don't ask) the bike just won't go. Sputters under any kind of load (we're talking 3,000rpm rolling away from stoplights), then won't rev, sputters, dies, and won't restart. No drama. Get the pump going again and all is well with the world.
I'm leaning towards a bigger motor issue, as well. Is it overheating? Check the coolant for oil, and check the oil for milky color. Follow PGK's steps. The smoke is oil... so you've got to find out where that's coming from. It'll likely be the source of all your problems.

When it comes to Ryan Jenkins, the story ends with me putting him in the wall.
