Hi Folks,
Changed the slave cylinder on my 1125r this Am.
Adapted a few tools for this purpose thought I'd let you see how I did it.
Nice to have a leak free casing for a change, god only knows how much was leaking into my engine oil so I changed that afterwards as well.
Not a bad Am's work.
Any questions feel free.

Good work.....that vice could do with repainting though. :D

Yeah, & dustin'.
I only sat the cover on the socket in the vice, little bit of wiggle & the slave dropped out. Same with the new one going in, as soon as it was lined up, a little bit of wiggling & it dropped back in. Just had to get a length of 3" by 3" & apply a pressured wiggle to get the tab to locate properly.
The clutch now feels very "Technically Accurate" although a bit heavy, I guess it needs to work a little to loosen up the new seals.
Pleased I got it done at long last.
I think that's my 1125r finished for road use now.

I'm surprised that it feels "a little heavy". One of the benefits of the Oberon slave cylinder is that it feels much lighter than the standard item. So much so that we fitted them to all of our EBR 1190RX and 1190SX demonstrators at PDI and urged our dealers to sell them to everyone buying a new machine.

Yeah, I'm pretty sure it's fine. I checked it all over a couple of times before & after fitting just to make sure everything was lined up correctly and flat against mating surfaces. :old:
It does feel much more controllable, just a little heavier action. I'm pretty sure it'll bed in when I've had it out a few times.
In the meantime I'll take the rounded nut on the clutch puller off again and apply a bit of silicone grease, see if that makes it a little easier.
The one I've just replaced felt like it had less resistance but not as much control & of course it was leaking enough fluid to need a pair of Tena panties.
Thanks for your comment. It's well appreciated. Paul.

Hi Folks,
Put some copper grease under the spherical clutch pull nut.
Made no difference to the clutch action, still feels a little heavier than standard.
I'll try bleeding it through again although it does work fine.
I'm thinking more & more that it just needs working to settle the seals a little.
All the best paul.

Is the vacuum pipe sealed and doing its job?

Hi Adam,
Yes it's all connected.
I thought the slave cylinder may have been slightly out of line making the clutch rod grab through the middle, but when I had the spherical nut off to grease it, I checked & the rod moves freely.
The stiffness feels hydraulic to me or perhaps the clutch springs are weak.
Still got to bleed it all through again just to check that's ok, Probably get that done tomorrow Am before going to see my Father in law in Sheffield on the bike if it's not icy.
Thanks for the suggestion. Paul.

Hi folks, clutch seems to be working fine after having the spherical nut off again & applying tension to the spring on the slave before tightening the spherical nut up. Perhaps didn't have enough pressure on the slave spring before or something but seems fine now. Need to get a run in before going to Sproutfest on it, hopefully later today.
Thanks for your help. Paul.
