I have a 99 banshee just put a modquad intake on it i am running stock cylinder just rebuilt the top end.it will run and all it will do is idle when i go to rev the motor all it does is bogg out.it acts like its not getting any air.I have torn apart the carb and cleaned them and that didnt help.I removed the tors on it and had a bike shop put on the tors eliminator screws on the carbs,im hopeing its just adjustment but i am leaning to a crank seal because i has oil on the end of the tailpipe.im stumped anything would help thanks justin
