There are several 161QMK variants. Verify your engine code, stud spacing and existing head configuration before ordering; a “200cc” badge or engine code alone does not establish fitment. This is not a standard GY6 125/150cc cylinder head.
Rebuilding the cylinder assembly too? Pair this head with the matching 164-340 cylinder kit, which includes the 61mm cylinder, piston, wrist pin, rings, circlips, head gasket, base gasket and chain-tensioner gasket. Those cylinder-kit components are sold separately from this head.
