Clutch fluid leak ?

[Tonyunn]

Since I got the bike I have noticed a small leak of what I thought was oil on the left hand side of the bike, I now believe it is clutch fluid weeping from the slave cylinder.

So I need to ask is replacing the cylinder easy enough, does it ease the use of the clutch if I fit a Oberon or Factory Racing type and is it easy enough to bleed out the system afterwards.

It is quite a simple job, you shouldn't have any problems with it. I went for a new OEM seal, and the difference was quite a bit, but haven't tried the Oberon one yet. There will be a few who have them that will comment on the difference in due course.

cheapest solution is to replace the seal

search here - i think a part was sourced for not a lot of dosh

READ kzmille's guide to bleeding the hydraulics - its in the aprilia tech section - makes life a lot easier

I would suggest that if you are going to change the slave, get an after market one - I rate the MotoPike and Oberon versions. The MPL is a pain - great when it works but try and get them serviced....

There is also the factory racing version, but I don't recall seeing any writeups on it. Then again, I may need glasses

The ones from motopike are factory racing and are £84 at the moment too.

Do they new slaves need a new gasket where they mate to the crankcase?

[Aladinsaneuk]

no they do not

Hi all,

Just fitted a Motopike one, got mine in auction for £63 all in. Easy to bleed, recommend fitting a hel line while you at it and on the top of the line fit a bleed nipple

[Tonyunn]

I take it there is no bleed nipple already as part of the system then?

That's clever of them. How do they expect it to be bled without a nipple?

[D-Rider]

There is a bleed nipple at the slave. Life is a whole lot easier if you fit one at the master cylinder too .... as air bubbles tend to rise. Banjo bolt with bleed nipple is what you want.

For that I guess you need an in-line bleed nipple. Where did you get one of those?

with respect to my learned colleagues

READ THE BLEEDING GUIDE FROM KZMILLE

if you follow that then you do not need a bleed nipple at the master cylinder....

[mangocrazy]

With respect to KZMille, it is certainly possible to do it in the way he describes, and if the procedure is followed to the letter it will work.

BUT.

It's a damn sight easier with a bleedable banjo bolt (also known as a bleed nipple banjo bolt), will take less time and is a lot less faff.

It's also worth noting that the later RSVs with radial master cylinders have one built in. Which is nice.

lord yes graham

BUT

it is possible with out it - and i think the real key is to reverse bleed

[D-Rider]

.... but for the price of a banjo with a bleed nipple and the ease it gives to doing the job - and makes a better job of it ......


(and yes, I have bled them without and made a good job of it but can see no good reason not to fit one due to all the reasons above)
