You'll want to check the float height, too. Both of my bikes they were set a bit high and fuel would leak out, and they tended to stall.
Also, if you're mechanically inclined, it might be worth taking the entire brake system apart to clean it (if it has Formula brakes there are some other things you can do to update them at the same time). It is well established that the rear brake master cylinders are particularly prone to "blowing" seals after a short time. This from crud that isn't cleaned out on assembly, then abrades the cup seal.
Minor issues, don't let them stop you from enjoying that NEW BIKE smell!!!
