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.

Great upgrade for Hondas.

Installed in my 05 crf450r and work very well. No power loss noticed. This is a high quality kit and beats others I have used and seen. Swirl polished valves and quality machined parts. I am a Tool Maker so I look for quality machining. Would highly recommend. My bike pulls on my buddies 08 rmz450 so I am pleased.

Its hard to compare before and after power, but there was definitely a lot of power coming from my CRF250R after I installed these!

These valves were perfect in my 2010 kx250f, they seated good and the springs and every other aspect of the valve kit went in my motor great! definitely recommend these valves and motosport for any engine parts!

Fantastic product! Quality looked amazing out of the box and brought them along with my head to local shop to have seats cut and kit installed. Hour later I was home bolting everything back into specs and my bike roared back into life. Incredibly pleased with the product and my bike feels incredible with this intake kit installed. Cant wait to get back where I belong!

Valves on 04 crf 250 R?
why are the base washers thicker then the OEM base washers and why are the springs doubled up unlike the OEM just wondering if i have the wright ones also do i need to lap the valves intake are new and the hesd is new and the springs are new but the exaust valves are the old OEM just wondering if lapping is required on the old valves and new valves or just the old or none. thanks

The kit for your 2004 CRF250x is indeed supposed to run double springs. It is not uncommon for companies to use dual springs to better help control the valves under high RPM conditions so they do not float. The spring bases are manufactured to work with these springs. These springs have a different thickness wire and the bases will be the correct height to compensate for this to put correct preload on the spring. For the valves you will want to lap them to the new head. It would be recommended to check with an engine builder to verify the old exhaust valves are in a useable condition. Typically when you have a new head it is common practice to install new valves to ensure the longevity of the valve train and to prevent premature wear of the valve seats. You only want to lap steel valves into the head and would not lap a titanium valve.
