We all know how important valve maintenance is on the four stroke Honda CRF's. Proper valve maintenance includes checking clearance and adjusting the valves as necessary. As frequently as this needs to be done, paying a mechanic to do this for you can get expensive fast. This application makes the process simpler for the person that intends to DIY. Along with "How To" YouTube videos and websites the proper maintenance of your valves can be much more manageable.

This application is for Honda CRF250R/X and CRF450R/X since the calculations require the valve spec values. The valve spec used in the application is .005in for the intake and .011in for the exhaust.

If there are any issues or concerns with the application please leave a review explaining the problem.
