Okay, Im new to building 2 strokes, but now Im really getting into the blaster project. I rebuilt the motor to stock specs, installed a pro circuit full exhaust, and have the the vent hole filters (8) on the air box lid and running the stock carb. Thats about all the mods Im going to do to this wheeler performance wise, but i have no idea what i should do to re jet it. should i start with ten over, 20, a kit? Maybe someone can help.
