Has anyone tried eliminating the stock, restrictive airbox on their new KFX. I am fixing to start on the motor in mine, and we have been discussing it. The shop I use (ATP) has had good results doing this on YFZ's, LTR's, and 450R's. The Yamaha kit appears to adaptable for a perfect fit. The quad will be for TT, and only be ridden twice a month, so trail dust, etc. will not be an issue. Also, will the Power Commander be able to compensate for this much additional airflow? Any insight would be appreciated.
