Also valve guides.

Does it do it all the time or just when you start it?

Check valve in oil pump goes bad and all oil from tank drains into crankcase. Rings can't hold that much oil back until scavange pump puts it back in tank.

White smoke is water- have you washed the bike lately? Possibly got some water in the exhaust pipe. If ur rings are going you would be getting blue smoke.
