Hey guys I have one more jet question. I am running a full fmf exhaust high flow air filter, removed air box lid and boyesen reeds I will also do the plus 4 timming mod. Where should I start with the main jet size also I need to know if I need a different needle. The yamaha tech said a 300 and a larger needle. Where do I buy these jets and needle and what's the difference between own and genuine mikuni? Thanks guys!
