95 Valk?

Sounds like the clutch slave, personally I would order the replacement parts from Honda, you may not need the piston, but I would replace any seals and sealing washers. Don't forget to replace the seal that the pushrod goes through since you are there, dab a little grease on the pushrod.
There was a lot of threads about this subject several months back, do a search and you will find lots of info.
