Hot Cams Cylinder Head and Valve Inspection Part 1

Hot Cams' Tom Morgan begins to take us through the inspection and assembly process on a CRF 250R cylinder head. Tom explains how to inspect the valve seats, valve guides, installing the valve springs, valve guide seals and then reviews how to inspect the cam chain and guides before bolting the cylinder head down.

@marek0086 If someone doesn't realize they should clean the parts, they have no business even taking the head off the bike.

Oh come on!.... u should at least spray the valve face and valve seat with some contact cleaner to get rid of any oil residue.... so the marker ink stays on the surfaces properly!
