I usually use second gear coming out of corners, so you may be over revving it. Could also be a worn out top end...

i suppose your idle circuit could be rich, since you experience the smoking when you take off real quick... maybe adjust the air screw.

I agree. Right side crank seal. Replace both. You may have to split the cases to change the right side. :(
You can get these almost anywhere.
Try

or any seal shop or good bike shop.
