ok my cousin and i just installed a new hmf slipon on his 03 Z400. We removed the snorkle and installed a 170 main. When riding it seamed like it wasnt to powerful at all. Im guessing the main is too big. We live in massachusetts about sea level and was wondering what everyeon uses for a main jet and if this could be the problem ?
