CRF250R Head Porting – CT Racing has done significant amounts of flow bench and dyno testing to offer you the best port layout for your application. We highly recommend getting a valve job at the same time the head is being ported. Our CNC valve job ties in with the port work to offer extremely effective flow numbers. $350.00 450R Ported Head

CRF250R 5 Angle Radius Race Valve Job for +1mm Exhaust Valves – The 5 angle radius Race valve job significantly raises the flow characteristics at low valve lift and definitely shows a horsepower increase throughout the useable power curve.
