Your OEM slave has failed or Oberon?
Mine is the original slave. I take it this is the up grade.
Yes it is one alternative and a very good one at that
The rekluse is another with the benefit of being able to "tune" out any clutch grab when your stationary at traffic lights
Ordered the parts there. Thanks guys.
I installed my Oberon last year and had no problem with it since. I love it!
So if I understand correctly, instead of putting mineral oil, as stated on the cap of master cylinder, I will replace it with the synthetic oil I use for forks, and that will work?
I know this is an old thread, just wondering about this last statement with using fork oil to extend the life of the clutch slave...?
yes I got the oberon after my stocker started leaking, I rebuilt the stocker and keep it for a spare my stocker went out on my in the last 3 hrs of a 5 day trip, I found out from many friendly people here that mineral oil is in many things and that it is also baby oil with perfume added, for me I had a slight leak and I was able to fill and bleed the clutch line enough to get me back home lol.
I did an Oberon swap...had the time and money...it took a while to do the swap due to some parts coming in at different times from different vendors. Now that it is back together with the aftermarket slave, I could swear it takes a little more ooomph to pull the clutch lever. It was remarkably light before, so this doesn't make it a deal killer...its not like the clutch pull on an older Ducati.
Or....maybe my office job has sucked the soul from me and people without a soul have weak hands.
3 weight fork oil for many years now, i change it once or twice a year and hardly changes color.
When i use the oem crap it took out the bore on the master, put in several overhaul kits but the bore was worn.
Since switching to fork oil all has been good.
My '04 950 made 25,000 miles before it failed,and my '07 990 only went 14,000 miles before it failed. So two bikes and two failures, that's a 100% failure rate for me. Do I win something for a perfect score?
My '06 950 with 8k on the clock left me stranded out in the sticks last summer.
One clutch pull it worked, the next, as I was coming to a stop with braking, it didn't. (That was actually a confusing little mental exercise. My brain knew that I was pulling in the clutch, but the bike was behaving like I needed to pull in the clutch.) I was actually able to laugh out loud about that weird mental push-up a little later.
A couple of things became interesting, right after that.
1) The bike starts on the starter in first gear just fine.
2) It is damned tricky to ride home, through a city with traffic lights and traffic, when you have no clutch.
For ref, it was dangerous....don't try it in a full blown city with lots of cars around. I only had to navigate about 10 lights total in 30 miles, with some being big, long intersections that had room to move. The small, city intersections were the dangerous ones.
I will say that traffic was off-hours, but it was still a drag to try to drive predictably when you are slowing down a half block from the light...so that it's green by the time you get there. Traffic didn't know quite what to make of me on that little drive. No whammies.
Interestingly, I had just gotten the bike, and did what I thought was prudent, by changing out the clutch reservoir oil. It was black and a mess. Within 2 weeks, the stock slave failed. Did it fail because I put in clean oil? It sure did seem like it. (The sludge was the lube.) I am sure it was very much on its way out already.
Oberon replacement. I saved my bux and didn't get the metal backer. Didn't see the point for what it needs to do (support the slave--or am I missing something???) and haven't had a problem.
Re; the commenting about office jobs sucking souls: My office job must have not sucked my soul (can babies see soul-less fathers?) or my Oberon hasn't affected my clutch pull. Mine feels the same as stock.
Mine puked today.
05 950 adv s, 12,000 miles. Havent ridden for almost a year.
Been riding a friends adv while he convalesces and working on my rfs bikes.
Forgot the clutch slave cyl crapped out last time out. While refilling with mineral oil i too noticed the black crud in mc reservior. Guess i will take apart the slave to see wtf. Ready to shell out for oberon.
Starter clackin, needs water pump, po had some goof jet the carbs not very well, hi maintenance whore....
Gonna flog her good soon as shes ready...
Good time to purchase directly from Oberon as the pound is down. And no need for the super expensive shipping/insurance.
I'm ready to order one of these for my SE, But I also don't see the point of the billet spacer. Provided the slave isn't overnighted to the point of distorting the plastic one, any subsequent usage from pulling the clutch pushes the slave back into the mounting bolts.
Stock cylinder, 7 years using baby oil, still working fine.
If it aint broke dont fix it. Mine broke. Oberon shipped yesterday.
I have issues with the bling word so, got my slave and spacer (yes unnecessary) both in orange so i could see how chain lube dirty it is down there.
Im thinking ATF for the additive protection, cheap, universal, have some on hand so its free.
Inspect and repair stock one for dust collection.
I see quite few references to over tightening causing an issue. IMO you would really, really need to torque on those bolts. There are 2 spacer sleeves that would also need to be crushed to distort the plastic spacer.
New slave on the way. Next question , Is there a difference in lever feel between 2.5wt suspension fluid VS. ATF? Also, should I disassemble the master and clean out the mineral oil, or just flush thoroughly with ATF/2.5wt
the OEM KTM clutch is 10x better than any brembo pieces
