This gives you enough room to get at the top and bottom of the carby.
I would start with JD red #4 but you might need to go to red #5 (or blue #3 if cool weather). Use a 48 pilot jet and a 168 main jet and you will be very close to what you need if not spot on. Leave leak and air jets stock for now.....

When folks "remove the subframe", they're only disconnecting the bottom two bolts and swinging it up using the top as a pivot point. This just frees up more room to access the carb - especially on the 07. And yes, you simply remove the float bowl and punch out the little metal piece for new fuel screw.
Hope this helps and good luck.
