Generally, you will want to keep the reed valves in place and cover them with a block off plate. APE sells them, or you can fab your own.

When did Kawasaki start using the reed valve technology on their KZ-1000 motorcycle? Would a 1977 model be so equipped? Thanks.

I think that in the U.S., the police bikes started using it in 1979 and the rest of the 1000cc bikes began using when the J engine came out in 1981.
