I just put my 08 motor in my 07 and everything else besides the motor and electronics is 07 including the carb. I cleaned the carb out while i had it out it was a little dirty. I started it up and it is very lean.. pops and wont idle down, the headers glowing in a matter of seconds. SO ... either I missed some dirt or the jetting specs changed from 07-08 Anyone know if the jetting changed? Thanks!!!!!
