Hello,

My clutch seems to not be working. I was told I could need to get a new master clutch cylinder.

When I press the clutch in, the clutch doesn't work, so my bike pops forward when in gear. And in addition, there is some fluid that leaks on my fairing. it ate my fairing. I am not sure if this is brake fluid or clutch fluid.


Attached are pictures.

Thank you!

The leak is coming from the main silver looking bullet thingy, and also some leakage in between the clutch handle bar.

Note I am not a mechanic, however, I can do basic maintenance.

From another forum:
I don't know how mechanically inclined you are but here's what your going to have to do. From what I can see from your pictures, it looks likes it dripping right at the clutch handle. This is usually a fault with your master cylinder piston seal leaking.

The part number for that is PISTON SET 22886-MAT-E01 its 34.86 us from honda direct line (american company)

You may also want to order the orings 21-22 and the crush washers #20. If you take the cylinder off the bike you will definetly need new crush washers. You are going to need inside ring pliers to remove part 21.

If you order form them it usually takes a week or so to get here. You can check with your local dealers to see how much it is in Canada.

In the meantime you will have to bleed the clutch to get the air out of the system. Suck out that crappy old fluid and put some fresh fluid in and bleed it. If you don't have a mityvac now would be a good time to invest in one.
link to a 2004 service manual same procedure for the master cylinder

Don't put your fairing back on until you fix the leak. You would likely get a much more detailed answer on a motorcycle forum specific to your bike. I don't have a cbr but a gl1500c, so the specific information I would use doesn't apply.

Hope this helps you.​

Yeah, pretty much looks like a leak. Isolate where the leak is coming from, repair the leak, and viola you're done..... If you are leaking fluid, you are not getting the proper pressure to operate the clutch, so of course it won't work.

So most likely I do not need the whole new master cylinder assembly right?

most likely not. I would guess you have a bad seal somewhere, couldn't really tell from the pics too well, but looks like it's in the clutch lever area? I would remove the plastics from the left side and pump the crap out of the clutch after filling it with fresh fluid. This should make it leak from the bad area. Simply go into the bad area and replace any/all seals....in theory you will replace the bad one(s) by doing this without having to tear down the whole system.

By "silver bullet looking thingy" do you mean the dome nut on the bottom of the clutch lever pivot bolt?
If so, then it looks like the seal in the master cylinder has failed.
If the bore is not damaged or worn then you just need to replace the piston. If it's leaking because the bore is scored or worn then you'd be better off just picking up a good secondhand master cylinder, bolt it on and bleed it up.
Use DOT4 brake fluid.
