going to build a 4 mil so these have to go. they were dune ported and bored to 64.5 september of last year. barely rode thru winter and have spent more time building than riding this year so this have low hours on them since the bore. they will come with jugs, pistons, rings, pins, circlips, and 8 stock studs. somehow i lost 2 of the stock studs when i swapped them for the cool head ones. my camera is dead now so i will get some pics tomorro. these cylinders have been really impressive to me and run real hard. the outside of them is polished and has all the builder info scribed into them. the pistons are pro lite. i also have some 18 mm domes if interested we can work something out. asking 375 shipped. i will ebay these pretty quick if no interst. thank you
