my kickstand is leaking oil.

If it's dirty brake fluid, it's the slave.

If it's engine oil, there is a good probability that it is the clutch pushrod o-rings.  The two tiny ones.  You can't see them until you slide out the long pushrod.  Cheap and easy to swap out.  Mine were done at about 10k miles.

Less likely is the output shaft seal or the alternator cover near the clutch slave mounting bolt, due to repeated flexing.

Be optimistic and change the little o-rings  [drink]

actually, it isnt oil. thats one of the first things you need to make sure off.

ITs dirty clutch fluid that leaks out and looks like oil. chances are the stains on your engine are not removable without some heavy duty stuff like 100% pure stem cell based cleaner.

If you remove your slave clutch (just take the 3 bolts off) you can look inside of it and see the orings. it should be the ones that are cloest to your body as your looking into it.

Honestly, just replace it with an aftermarket one. they are cheap these days and always on sale if you buy the not so well known brand ones ( honestly they all seem to be high quality copy cats of the original 2, yoyo and evo since its hard to deviate from their design.)

so one of these http://www.monsterparts.com/pc/90041/CB-Parts/90041.html
and some push rod orings from the dealer it sounds like.

so... drain clutch line, disconnect clutch line, remove slave.  Replace orings on push rod.  install new slave, reconnect clutch line, fill with fluid and bleed?

He forgot to tell me that - must be proprietary info - those experts don't want us hacks to know everything

As another helpful suggestion - you might try a wrist band on the kick stand - I prefer Adidas

i just found a speedymoto wrist band with billet adjuster ring. i'm going to get it in gold......shinny gold. ;) ;)

If you want to cover all your bases, or you are sure the leak is brake fluid and not engine oil, or if you simply want an excuse to get a fancy slave cylinder, then by all means get a new slave.  All are good reasons!  Pushrod o-rings are cheap and quick, and just might solve your kickstand issue.

I like to swap the slave line as quickly as possible, with as little line drainage as possible.  Makes it easier to bleed all the air out and get a lever back.  I even pre-fill the slave a bit with a syringe.

Your problem could be the slave, pushrod O rings or the side cover.  The disengaging and engaging of the clutch flexes the side cover in that area.  Over time the sealant can tear, causing a leak.  Follow ducpainter's advice and get out the aerosol powder.

I'm having the same leak Andy, wanna grab some 0-Rings together we can fix them at my place.. It's really easy to do the job just gotta make sure you lube the o-rings before you re-install..
I guess there are good and bad mods; you'll find the good ones here ;)

Nope, just get some pig-tail picks from the local hardware store and pop them out. One could actually do it with a tooth pick and squeeing the ring, but it's a little hard to explain on the interwebs.

maybe.  I'm going to order a new clutch slave and replace that while I'm at it.  I'll let you know.

Chain oil also tends to build up in that area, I have not seen mine drip but every time I replace my front sprocket there is always alot of chain lube to clean up.

replaced the pushrod orings today.  The old ones seemed worn down compared to the new ones, at least to my finger tip.  Local dealer didn't have any aftermarket slaves, so I'll order one and replace it when it gets here.  Getting the orings off took longer than getting it apart and putting it back together.


Thanks everyone.  Hopefully that solves it.

New clutch slave arrived today (thank you monsterparts) that I ordered monday.

I've never done this before, any tips?


Any recommendations on brake fluid?

Yes, new brass washers for the fittings and pre-fill the slave with brake fluid before assembly. Don't forget that brake fluid is caustic to paint so be careful there. As for bleeding, if you are not familiar with the process, ask someone local to show you. once you learn it; it will save you lots of dealer labor doing your own brakes and such.

If you can, get a helper. They can mind the fluid level in the res, while you keep an eye on the bleeder line. It will talk a while to get the last of the air out of the line when you swap the slave, probably a couple refills of the reservoir.

One other simple trick is, after you're done bleeding it, pull the lever to the bar and strap it down. Leave it that way over night or a bit longer. That can help let any last, troublesome bubbles filter up into the reservoir.

Oh, and have everything ready for your swap in place and ready to go before you break the seal. Once you open it up fluid comes out a good bit quicker and you'd think.
