05 Vector leaking oil

[mikextx]

Buddy has an 05 vector that leaks oil. He says it only does it after running WOT high rpms. Oil goes into the airbox, then runs out and down. Leaks out of the bellypan. Cant seem to find the cause. What could cause excessive oil in the airbox? Any ideas?

The 3 cyl is famous for this. They are sensitive to overfilling the oil 1st and foremost.

2nd, make sure none of the breather lines are kinked.

Your crank case vent line is kinked It happed to me and that what is was the line is on on your mag side that goes to your air box
