What I have are vito 421cc 68mm ( dune and triple exhaust ported) cylinder, they are really powerful.
but they need to be replated or resleeved. So I am going to sell it for $125 shipped
I also have some WSM heavy duty sleeves (bore sizes range from 64mm to 69mm )that can be used for them cylinders, just make sure you take it to a professional atv machinc to they can match port as well. The sleeves are brand new
I can sell both for $200 shipped
