OEM front fork spring

The Kawasaki manuale its a mess. Since english isnt my language, im Not sure about the free lenght of the fork spring for the KZ 550 h.
I have to overhaul the forks. The only thing i understood is 235+/-2,5 cc of oil for each leg.
Can someone tell me the service limit for the spring lenght? Thank you in advance

There wasn't any fork info in the supplement for the 83 550H, so use the 82 mode supplement.

1979-83 550 Kawasaki service manual. page 382-83. Front Fork KZ550H. Table N68.
Fork free spring length. service limit = 584mm.
