Show how to properly shim and adjust valves on a 2002 CRF450 to get the gaps between the cam and valves within spec (0.09-0.15 mm Intake) and (0.25-0.31 mm Exhaust gap). Bike started and ran great after changing out valves to stainless steel valves from titanium which are more durable but require heavier springs.
