I just got a leftover 07er recently and from what I read on here the R is pretty restricted from the factory as far as jetting and air box goes. I also noticed it hesitates when you punch the throttle from idle and I even notice it when riding, dont know if it just needs broke in or sounds like could be from what I read on here that is the leak jet. It is pretty cold here right now 0-30 degrees but most of my riding will be in spring to fall

What im wondering is what should be in this thing for jets with everything stock, lid on for now. I am in iowa bout, 1000ft normal temps in summer 70-100 degrees.

I know this has probably been asked numerous times but thanks in advance for the help
