Pair of 1979 KZ1300 with recommended upgrades Sell one or Both

I am selling one or both of my KZ1300’s.
Each has a Vacuum pet cock installed.
Each has the Upgraded cam tensioner.
Each has Accel Coils and wires.
Each has had the charging system wires butt connected.
Both charge Good.
Both have battery charging monitors.

$4000 and $6000
Selling because I’m in my 70’s and I have two other motorcycles, a sport bike and cruiser. 
One has mid 20K the other mid 40K. The lesser drives like a new bike. The other is just sweet. 
Neither has had the cam gear replaced.
