Great kit, installed into a crf250x with no issues hopefully will last for a long time. Very complete kit packaged well and each item was individually bagged.
Since 1938, Kibblewhite has taken great pride in their ability to design innovative performance improvements for the valvetrain. This innovative ability has never been more apparent than with the development of the high-tech lightweight stainless steel conversion systems for the incredibly stressed and torturous environment in today's ultra high revving 4-stroke singles.
The challenge to engineer valvetrain that would outperform O.E.M. systems that in some cases included titanium components was not an easy one. This task would require the concentrated efforts of every member of Kibblewhite's design team. It was apparent early on that a lightweight high flowing Kibblewhite stainless race valve was not going to be the complete answer for these engines. Working together as a team enabled Kibblewhite to evolve with a "unified system" approach. In fact, this innovative lightweight system would not only out-perform factory parts, but outlive them as well.
Notes: For applications with low hours and / or apparent intake face recession and exhaust components that meet factory specifications, consider Kibblewhite's Intake Only Systems when performing necessary service. Bear in mind that Kibblewhite does not advise partial conversions on race bikes and / or engines that have reached factory advertised service limits. Always consult with qualified professionals suited to inspect your machine.
