It's normal.

 

Blue smoke = gas usually or a little oil

white smoke = water and disipates rapidly and doesn't linger around

black smoke = oil or way way too much gas



Rotary engines run super rich when they are on the cold start cycle and warming up because they get really shitty combustion when they are cold so it will smoke a little blue untill it warms up and can get good combustion.. The computer also dumps about 20-50% more fuel than normal on the cold start / warm up cycle

 

Thanks for all the comments.. I'll just keep it topped up and drive !!!!.. that's always the best bit..
