On the KX450F, we suggest using stock jetting based on our testing condition. These specifi cations should only be used as a guideline. Riding at different elevations or climates may require using different settings to obtain peak performance. If you need additional assistance, please refer to your Kawasaki owner’s manual. 2. To convert system from Offroad to Competition specifi cations, remove the 5mm Allen bolt and Spark arrestor. Two different Db lowering inserts are also available (see accessories section on page 2). To return the system to Offroad specifi cation re-install the Spark arrestor into the rear of the muffl er using a small amount of blue thread locking compound (Loctite┬« 243) re-tighten the 5mm Allen bolt (6.5 ft pounds)
