Smoke Problem

When I get to high RPM's like around 6000. When I shift. there is a lot of blue smoke that comes. Obviously oil. But where could that much extra oil burning. But can I do to stop this or slow it down. All help will be greatly appreciated!

Sounds like your oil rings on the inside of your rotors are going out. It should last a while even while doing this, but it's a sign that rebuild time is coming. There isn't really a way to stop this without changing those seals, and to do that you have to tear the motor apart. I would say use a little MMO in with the oil and try and prolong the life of the seals. Many rotaries smoke after a certain RPM. I get a little smoke after 9,000, especially when downshifting.

Well, it mostly smokes when it has sat for a period of time. Otherwise its fine, I figure as long as shift before 4. I think I will be fine.

Yep, oil control o-rings are getting worn. When you let off the gas the sudden vacuum allows the oil to be drawn past the o-rings into the combustion chamber.
