Hydraulic clutch

[Dool]

Eventually all the bubbles of air were gone and the system works.
I used a cheat to back flow the system from the Bleed valve with this pump, then used the garden hose to wash the Brake fluid off the ceiling .
Fitting a Cable is Kids play in comparison, the force to pull is reduced as is to be expected as the slave is 12.7 and the Clutch Slave is 14mm.
Not saying how long it took to do this job.

I take the entire thing as a friendly warning - which I would have hoped to have gotten earlier. ‍‍

I'll take advantage of your experience and forget about fitting one!

 

[Dool]

Ah, but you will never know if you dont try it
I did some of it wrong, firstly the Master Cylinder dazzled me and I didnt notice the single bolt mounting ( Grip has been cut and reglued 3 times now !) I had to remove the Pin that locates the Switch Gear.
The Clutch switch is also different having but 2 connections so that needs bypassing/whatever.
The cost of the Kit was $66 I wasnt expecting too much, check these ones! Double the price ( different piston sizes also)

EDIT, quadruple the price!

This clip caught my eye, it was on the ground near my bike, on the right hand side under the new Gold Slave Cylinder.
It is not a high quality E Clip and is thick and wide, after a look see I found it had come from the Pivot Pin of the Master Cylinder which is not machined enough to allow this style of clip. Leverage is not much good without a pivot pin!
Buyer beware, some of this stuff is just Too Cheap, I have fitted a better E clip and now am looking for a different Master Cyl

Experiment is not over yet, fitting the first is the hardest, just like the oil cooler took 3 coolers for only 2 Bikes.
S.I.I.W. is the system I employ here as I do not have C.A.D. installed

As much as I like the colour the Master cylinder has lost my confidence, I have ordered its replacement which conventionally uses a bolt and nyloc nut for a Pivot Pin and has a 2 bolt clamp and a Mirror mount. But still cheap as, so little I have learnt
It comes as a package with a Brake Master cylinder of the same size (14mm) with 6 position Shorty Levers, adjustable which are Gold as is the Cover of the reservoir, couldn't resist it
Now the piston size has increased by about 20% on the Clutch Master, I have checked my 14mm Slave and it can go a few more mm!
It would be presumably 20% harder to pull, if that proves to be too much I have a 16mm Slave.

With the combination 12.7 Master to 14 Slave I first thought it was borderline as the movement is only about 11mm, my fear when I did the 0 to 100kph test was that the clutch would slip because I had taken out most of the Free Play to get maximum travel, presumably that didn't happen.

As for the 14mm Brake MC, now I will find out what size the OEM is and perhaps play with the Brakes also, or just swap levers

I know why Sam's Clutch was so hard to pull.
The Master Cylinder is 19mm!!
That pushing a 12.7mm Slave so it's designed to be Quick action.

so do you have a solution for me for sale? otherwise the hydraulic goes out on monday ...

 

[Dool]

Your only hope with that Master cylinder is a bigger Slave cylinder.
19mm is the biggest ive seen so far. about 40AD from China.
So thats a yes I suppose

How have you put up with it that long ? your Slave was 12.7 was it not?

 

[sam2019]

your Slave was 12.7 was it not?

I would not know, it wasn't telling.

 

[Dool]

Now it is more attractive!

with music ... !!!!

I think that the coolest thing about this is the Key Lock! Nice theft deterrent! Oh, and the color, of course!!

I went back to cable today - what a relief! as soon as the new slave arrives I give hydraulic another shot.

The Colour of course goes well with the Black, this one is getting the chop as soon as I get my new set which is slightly bigger at 14mm.
Now I want to play with my brake

 

[Dool]

But overall this Set up has performed well, great feel and the ability to shift the position of Take up by adjusting the Lever,
Next Challenge is H1 ( currently 471cc ) it gets the bigger Radial Master Cylinder and a 19mm Slave

Clutch Pull Weight.
So with this little Digital Luggage Scale I first tried the Manual Clutch, then the Hydraulic, no surprise the Hyd was a bit less.
Here is the Manual.


And the Hydraulic

A third less pull. That’s a win!
