put in a 155 mikuni main jet your running way 2 lean dyno jets are smaller than stock jets and the ones they give you are not big enough to support a open air box and a pipe you would need about a 165 or 167 dyno jet to equal a 155 stock jet and i"d bring that 155 up once it gets cold out i ran a 155 in mine for a while but then i did a 440 and a 40mm carb and ct sonic pipe that should get you somwhere close but every machine is different
