there is a seal on the KIPS shaft...part number 92049-1238, and if it's worn/leaking, then it will show a little more black oil than normal when you pull the cover.
you could have a bad clutch side crank seal too...which would allow it to suck tranny fluid and burn it, causing the excessive smoking...a possibility.
and if it does have a bad crank seal, you'll never get it jetted correctly.

There is a lot of oil. It poured out when I pulled the cover. I have been lucky not to pull the cases apart but I think its time to just do it.]

yup...then you'll know what you have, and can start fresh with a tight motor.
DP3601:
When I pulled the exhaust valve cover this is what poured out... Not good!
Ive been putting off splitting the cases so I decided it was time to replace the bearings and seals through out the engine so I know it would be nice and tight.
DP3601:
Motor pulled, trying to decide if I want to powder coat the frame while she's apart.
Motor pulled and it begins..
DP3601:
Pulled the cover off and they had no gasket, so there is a little bit of a mess I need to clean up.
