is the oil injection still connected?,it moderates it pretty good and dont smoke very much,also you can check to see if your losing oil by drain it and measuring it,funnel directly into empty bottle oil trans oil,but the amount that it is leaking may not be so apparent...does it smell like it is burning,other then the 2 stroke oil, or is there oil leaking out of the cases out of the bottom of engine....i believe what blaaster said about seals is the problem...unless you are leaking oil on the ground.!
