Ok first let me say hi new here ,just picked up a 77 cb750 basket case Monday now going threw the motors to see what I have . One is a 71 110# the other I'm thinking by what I found it should be a f2 motor with anymore 260xxx . First question are any parts swappable between these two one blew a con rod in number one cylinde. Trashing the sleeve that jug is need of releave etc . The other (f2) motor has four stuck pistols but I've flipped it and split the case and all the internals are clear showing minimal wear clean so that need cylinders and pistons at least . But really what can I use between the two ?
