We built the motors for some of the Factory Polaris team efforts, competing in the Score and Best in the Desert Series. We worked with Teixeira Techs owner ED Teixeira, building his Best in the Desert motors going into a completely hand built quad even before there were production KTM powered quads. In 2007 CT Racing owner was Coaxed out of racing retirement to compete in a Polaris Factory sponsored racing effort, Works and GNCC races. The experience we have leads to very fast, reliable motor packages. Our massive amount of Flow Bench testing and Dyno Development has led us to develop a CNC port Spec for the KTM head that is second to none. Combine our CNC porting with a CNC 5 angle radius valve job for unmatched performance. This kit works equally well for both the 450 and 525 motors. This Kit even offers a jet set making it a plug and play set up. |

| 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 |  |
| 3 Angle Valve Job – Quality valve job. | $144.00 |  |
| 5 Angle Radius Race Valve Job – 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. | $192.00 |  |
| 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. The 5 angle valve job really shines on big valves as the seat diameter is opened up all the way into the aluminum casting, blending to the port work. Adding +1mm valves to a modified engine package helps the mid to top-end horsepower. Most aftermarket hi compression pistons are clearanced for +1mm valves. | $240.00 |  |
