Hello does anyone have any info or experiance in fitting gpz 750 or gt750 barrels , pistons and head to a z650

my z650 has the later hyvo cam chain

hi mate just fit the barrels and pistons and use the top half of your own engine i done it to my old zed 650 then you might have to muck about with the jetting in your carbs depending on what exhaust and filters you have :kawa
