It should start and run out of the box. Fine tuning a Mikuni seems a little tricky but once you tune one you'll get it. I recommend watching a good YouTube video that explains the process.

Most likely you'll just be playing with the idle air/fuel jet screw and idle speed screw. Both are super easy. The main jet should be good, that's the wot. The needle setting will fine tune the midrange.

This is a good one

VM vs CV vs Flat Slide is chocolate vs vanilla, but the tuning process is nearly identical.

What questions do you have?
