My 99 has a small leak at the bottom of the clutch slave. It's about a drop every ride (I reach down and wipe it off with my finger). Anyway, do I need to bleed the fluid before I pull off the slave (or is it sealed like brakes are)? Is there a gasket between the slave and the motor case (mabye I just need to tighten it up to stop the leak).

 

I'd like to pull it off and inspect it before I order a rebuild kit. The bike only has 9k on it and the fluid looked pretty dark. It could have been the origional fluid for all I know. So, I changed it but it still leaks. I know water in there could have caused some damage. I might get lucky and just need to give it a good cleaning....might have some gunk stuck under the seals.

 

Thanks

If its leaking fluid I'd say it needs a rebuild, there is a gasket between the slave and sprocket cover, but it doesn't hold any fluid or anything. You can unbolt the three bolts holding it on and it will still be sealed until you crack the bleeder or remove the hose. Rebuild kit is about $20, very simple procedure.



EDIT:

I'd also like to add one thing, if you're gonna rebuild the slave, its usually a good idea to go ahead and do the master too. They use the same material for seals, so if they are both stock, when one is ready for a rebuild, generally the other is too.

I use a syringe to remove all the fluid from the master before removing the slave or a caliper. There's less mess to deal with. Just in case you are unaware: brake fluid will remove paint.

To be completely honest, I usually buy whats cheapest. I've used everything, including OEM, and I've never seen a real difference.

www.v4market.com

 

Brain Backman is the owner. Tell him Jeff in Franklin TN. sent you. I believe his is located in Conneticut. He sells K&L brand rebuild kits which are made in Japan.

My local Honda's website says the 98 and 99 models use the same clutch master cylinder kits. 2000 models were different. Looks like he has what you need in stock. Including the clutch slave kit.  If not, he can get them. I have purchased 20+ kits from Brian and have had not one problem with the kits.

PM me if you want his phone # if you'd rather call. Doesn't always answer but he will call back.

You can get these much cheaper from v4market than you can from Honda.

Yea, I think I'm going to just do a rebuild. The master cylinder looked pretty clean when I did the fluid change. It operates smooth and firm all the way through the lever pull. Does it really need to be rebuilt? Does anyone have pics/video a rebuild?

Since the slave cylinder is leaking then yes it's better be safe than sorry. It's very likely the rubber seals in the master cylinder are the same age as the seals in the leaking slave cylinder. Keeping clean fluid in the hydraulic systems will definitely give the MC's etc a longer life.

If you have any mechanical ability at all....rebuilding the hydraulics on motorcycles is a walk in the park but it does take some time.
