If your dont ride the banshee like its made to. The oil will start to build up. When I ride trails in the summer, I have to give the bike a blow out run and oil will be all over the pipes. But in the dunes I dont have a prob at all because it gets ran at WOT alot of the time burning the oil fully.
But with the color of the smoke being white/gray I would do a leak down like said above.
Also, the pilot will only effect the idle to about 1/4 throttle.
