Today I did a valve adjustment on a 2014 KX250F. Here's a step-by-step video outlining all the major steps involved in doing a complete valve adjustment. This is very similar for all 4 stroke Japanese race bikes except Honda. Kawasaki, Suzuki, and Yamaha have run very similar setups in their race bikes for years.
