Clutch Master Cylinder Maintenance Kit

[SaturnV]

Posted this under Brakes section as couldn't see one for Clutches - similar system re hydraulics anyway...

Bike has been sitting in garage for several years now and only used occasionally 

Issue has been happening for a while anyway, more often during winter / cold weather - Clutch lever had too much free play so I'd bleed the line via the nipple at the engine casing point which always seemed to do the trick; until the next time!

Anyway recently found that bleeding didn't make any difference and lever remained 'completely floppy' so assumed that must be as issue with the master cylinder or reservoir seals.

Bought a refurb kit and waiting for warmer day to fit - anyone else had this fault - any advice on how easy / straightforward this job is please?

Not much to it really, you will need a pair of internal circlip pliers, silicone grease, DOT 4 brake and clutch fluid and a bleed kit (5 mm ID clear plastic tube and a jar). There's a boot, push rod, circlip, piston and spring, pack the boot with silicone grease to protect the piston. Maybe have a gander inside the clutch slave cylinder while you're there, always a good idea to clean the slave cylinder push rod it gets fairly gummed up. Its all in the manual.

Yes I always pull the rod out, clean and lube it.
If marked (worn), turn it around (end to end) so it doesn't all wear in the same place.

Update: Fitted the all the parts that were in the repair kit (i.e. piston, seals, spring etc.) correctly as per the manual then refitted the reservoir and filled with DOT 4 fluid.
Attempted to bleed but clutch lever still has no resistance, in other words my work made no difference whatsoever 

So can only assume that the fault lies elsewhere - next thing to check will be the slave cylinder I guess?
