I purchased a 1979 KZ1300 that is a US import and was wondering if you can buy a kit to blank off the reed valve set up or do you need to make the blanks? also need a L/Hand reed valve cover as mine is missing, if anyone has one for sale.

There are no reed valve delete kits available that I know of. . There is a  ZN1300 Valve Covers Breather Assembly   available on EBay USA.

If you decide to delete the air induction system, you will have to block the ports that feed the fresh air to the exhaust ports and that can be done with either high temp epoxy (Scotch did it that way and still holding up ) or drill/tap/plug the ports.

Tyler also did a Air Injection System delete and used 3/16" aluminum plate and fabbed up his blanking plates. See  Tyler's reed valve delete cover plates pic

No kits are available as far as I know.  As kawboy said I traced around the reed valve covers and cut out blanking plates from a piece of 3/16" or 1/4" aluminum.  I put the reed valves in and then bolted the plates over the top to seal them up.  It really cleans up the top of the 1300 removing that nonsense.

I would also add that you can tap the fresh air port that feeds into the exhaust port in the heads and plug them with set screws.  I can't remember what size, I think it was like 3/8 or 5/16 fine thread ( 8mm to 9 mm).  The casting hole was was nearly the exact size one of those threads needs for a tap, didn't even have to drill them, just tap and plug with a screw.
