I made a hydraulic clutch for my 400, using the seal from a hope master cylinder (10mm ish), and machining a cylinder and piston out of some aluminium. Worked really well and the clutch was really light, too light for me really. I ended up swapping back to cable with a bearing in the pivot.

I've just mocked it up so you can see roughly how it looked

Nice work and overall concept am.

Yes you'd certainly get a potent ratio with that bore size, think you're right at 10mm or they may be 10.5mm. Probably from a mc like this one

Same concept by pulling but using a piston and seal from a caliper at 15mm (still with mc shaft seal though) and perhaps a coil spring in blind end of cylinder to help return piston and avoid holding force against clutch could be a development step.

Thinking that through  :) it's the other way round regarding ratio and slave bore size. Larger piston will give less travel and more power to accentuate how easy it is to operate.  Hope now make a smaller mc piston (9mm I think) in their 4 series brake system that may help, but with this of course adding to the bike's original ratios accumulated from the cam and cable lever effects built in .

You'll likely need the bigger sized piston if going straight to the clutch push rod as it will delete those leverage elements built in above.

I actually asked for beige! ;D

New levers came today, adjustable for length, span and the move up and pivot  rahher than snapping. I had them made by a pal abroad..really rather impressed TBH     The wheel rims and spokes came as well via Parcelfarce. I asked to have them delivered to the PO in the village  as I wouldnt be in so of course when I came home they were on the door step in the street being splashed by the tractors.......... surrounded by idiots! ;D ;D ;D

What colour is the frame Roo in some shots its looks pewter-silvery, some bits black - is it heat sensitive paint or an odd lighting effect ?

I knew I should have stuck to the colour that dare not speak its name " tun nworb"  ;D ;D ;D
