A while back someone posted about rebuilding their clutch slave and there also may have been something about a cable retrofit. I've installed new seals on mine but the leak is still there. There didn't appear to be any significant wear on the piston or the cylinder. I may have put in the main seal backwards so if anyone has any photos or can give me some direction it would be appreciated. The cable conversion would be ideal as that assembly is a real pain in the ass to fill and bleed properly (especially when it starts spewing out fluid after you go through the whole procedure). Thanks Mark Attachments:

I may have put in the main seal backwards... Most likely - I've rescued some very corroded FZ slave cylinders and they've all been ok when cleaned up and new seals fitted. They are a pain to bleed; you often need to leave them overnight and then crack the banjo union on the master cylinder. Once you've got it working it pays to change the fluid at least once a year - the fluid absorbs water which settles into the slave causing corrosion and making the seals fail. The cable conversion uses XV1100 clutch parts and CNC machined bits and is eye-wateringly expensive. Mine cost over £200 even with the XV bits, cable and lever coming from eBay

I found that old posting last night and one of the photo's confirmed that I had the main seal in backwards. I'll try again and see what happens. Do you leave the master cylinder cover off while you let the fluid settle? Also, any idea what the spec is for the cylinder bore diameter? When you put the piston in without the seal it seams awfully sloppy. I wouldn't mind seeing some pictures of your cable conversion. I saw one on a site by someone named Gavin call "Building the Beast". Looked kind of homemade but a pretty good job. Thanks for the advice. Mark

I don't know the dimensions but the seal does take up a lot of space. The site you found is mine . The cost is mainly in the CNC machined housing which is a copy of the original kit part - the program is owned by a guy in NZ. I haven't used the bike since it was fitted but I will be testing it next week. I'm not really expecting any difference in performance...

That did the trick. Got all of the residue out of the cyclinder and put on the seal in the right direction this time. That tip on bleeding from the top was a big help too. I'd be interested in hearing more about the cable conversion. I've got a friend with access to someone with a CNC machine who's been able to get some parts created from models made with rendering software. Not sure which one. Nice job "building the beast" by the way. You guys are way out of my league but here's a picture of my old beast just for record. Mark Attachments:

Hey Not sure of the seat's orgin. I retrieved it from a bin at Shannonville Motorsport Park back in the late 80's. Cut in half and widended to fit the frame and a bit more augmentation. Thanks for the links on cable clutch retrofits. Might get to that after my plans for the Brakes, Wheels and Front end are realized. Mark
