Not sure of the jetting how can I check I have the main jets and everything sitting out of the carbs. It's got a moose racing boost bottle, Tommy t5 pipes. I'm not sure on how to tell the rest. Never had to deal with this. The left pipe was blowing think white smoke and oil and the left carb which is the choke carb was dumping gas out the overflow lines and covered the whole left side of the engine in grime
