Title: MC Leak After Clutch Bleed???
Post by: arai_speed on May 28, 2009, 11:05:11 PM
I recently bled my clutch and I noticed afterward that I have a small leak below the MC, right  by the microswitch.  See pic below:

I cleaned the area an inspected it and it look ok.  I went for a quick ride came back and noticed some fluid build up under the microswitch.  I would hate for brake fluid to leak all over my bike or gas tank  :o

Do I need to bleed the clutch again?  I'm not sure if this is just a build up or air bubbled in the MC that could be causing this.

My bike is a 07 S4RS and I bled the cltuch the old fashion way.

Any tips are appreciated.

Thanks.

Are you sure it wasn't just a little that you spilled when refilling the reservoir?

Bleeding won't stop or create a leak.

Yup, pretty sure.  I cleaned the whold area with a damp cloth and it sat overnight.  I then went for a quick ride and noticed build up.

There are no other leaks anywhere or build up around the MC, just under the microswitch. 

Here is a pic I took this morning with no build up.

When I first bled the system, I noticed that I if pumped the cltuch lever and pressed the rubber boot, a tiny bubble would appear in the hole next to the microswitch, it did that only a few times and hasn't done it since.  I pressume this is where the leak is happening but can't be certain  ???

If it continues I'd suspect a bad master.

At this point if the clutch is working well I would just keep an eye on it  A leak at that hole would mean either a porous or cracked casting, both would be rare.  If it was the front brake I would be more concerned.

Thanks for the replies.  I'll keep an eye out it to make sure all is well.  I took the bike out for a spin yesterday afternoon and didn't notice any leaks.

How much would a new MC cost if this one is indeed going south?
