Athena 50mm 80cc power valve cylinder kit for Minarelli AM6 engines. 

This cylinder is a monster. Big ports, big bore, big transfers. Most importantly, it has a exhaust power valve! 

Not for beginners but does come with a set of assembly instructions.  AM3-4-5 engines must be case bored for this to fit. Athena claims AM6 should not need case boring but it should be checked that the piston does not interfere with the cases at bottom-dead-center. 

Comes with a big bag of hardware, gaskets, power valve assembly, cylinder, head, piston, ring, pin/clips.
