1986 fzx700

Help Please. I have a new to me 1986 fzx700 pretty nice condition with 1 problem. Yha clutch was leaking. I replaced the seals in the clutch master cyclinder and the plate on the clutch cylinder itself. The person I got it from ran it out of fluid so I figured it may be only because of the leaks. On the center stand the bike starts fine runs I put it into gear and the rear wheel turs for about 19 sec. then stops rotating. The clutch lever is now hard as rocks. If I loosen the bleed valve on the slave cylinder and depress the clutch lever it all happens again. Is this an indication of a hydrolic lock or are the clutch plates and or the presure plate junk.

Thank you Midleagemayhem
