25
Inner surface cylinder color indications
Unpainted: standard steel Orange: chrome plated Blue: Nitrided barrell green: 0.010 oversize yellow: 0.020 oversize
26
Sparkplug paint?
Yellow: Long reach 13/16" thread depth No paint: Normal reach 1/2" thread depth
27
Function of compression ring?
provides seal for gases in the cylinder and transfers heat from the piston to the cylinder walls
