900 ss [clutch slave cyl]
 

can anyone advise to a constant problem with me [bitch] sorry 94 ss clutch slave seal keeps leaking have replaced entire item lasts a while then goes same way the belows keeps swelling up to so rubs on the chain use spray chain grease which is not supposed to swell rubber but it does plus its a tw*t to bleed up any advise as to this area of me hoe is much appreciated ta geezers....

There is a modified piston available made by Evoluzione from the States. It's made from alloy and carries three O-rings which is a far better sealing arrangement.
I have a couple in stock @ £18 each.

When you say you have replaced the whole unit, do mean just the piston or the entire slave cylinder assembly?
If you have only replaced the piston and still suffering, I'd guess the cylinder is worn/corroded and needs renewing??

Drop me a mail if you need any more info/help.

fitted a yoyodyne (think that is spelt right ) to mine never been any trouble since, looks nice as well
