My 250X has '05 R cam, R header, R exhaust with PMB endcap with spark arrestor and pink wire cut. Airbox fully opened and rejetted. When my intake valves closed at about 180hrs I replaced with Knibblewhite stainless and put in a new higher compression piston/rings and replaced cam chain. My bike rips and sounds great, although my 15yr old occasionally gets dirty looks when he rides around the neighborhood
