what mods did you do to make you change jetting? What jets were in the carb that you took out? i run stock type jets and i know there all different sizes and that makes it hard to help when people run jet kits. But with my 558 kit PP pipe and the baffles and end cap removed a 175 stock type jet is way to big. I think the dynojet jets are bigger in size. Pull your spark plug and look at it. not at the end but up in under the threads. Also you may want to check vavle clearances.
