Topic: CB750 cylinder compatability

I need a set of cylinders for my motor from 72. Just wondering if later years can also be used? Any help appreciated.

Yes through 78K will fit as well as 75/76F.
The 77/78F2 have some differences.

If your 72 750 was built after 3/1972 it may have the 8 rubber 'dowels' around 8 short steel dowels in the inner stud holes.
If built before that, these will not be there.
Either type will work, but if yours doesn't have them now and your new cylinders have them you will have to change your gasket kit to the later type to get the seals. You can probably also buy them separately, but you'll need the little metal dowels, too.

I have a set (2 actually) of cylinders with pistons and rings that are bored 836cc size, if you're planning on going that far. The customers changed their minds about the big-bore AFTER I had them done(!). They are available for what I've got in them, with or without a cylinder swap in trade.
