Do a proper carb clean by removing the carb from the bike. It's pretty easy to do, though the first time will take longer as you'll want to remember how everything goes back together. As for air filters, I probably wouldn't bother changing to anything other than a stock filter unless you want to change your jet sizing/exhaust (or debaffle). There are hyperchargers available, or you could do the DIY scooterizing/grampsizing. Performance gains are debatable, however it feels like I gained a bit of power when I did it to my bike.
Never argue with a fool: onlookers may not be able to tell the difference.
