If you're using the stock filter and air filter box, check the air filter if it's in good condition.  If it's dirty, replace the unit with a stock OEM, quality aftermarket, or upgrade to a K&N drop-in replacement air filter.  A quick test to see if your air filter needs replacement is to remove the air filter and hold it up to sunlight or other light source - if you can see light, it's still good; if you cannot see any light, change it!

Note:  the bolts that secure the air filter in the stock air filter box tend to pull out their anchor fasteners on the bottom.  When tightening these bolts, do not overtighten!
