Clutch Fluid Replacement

I finally got around to bleeding my clutch today and this is what I found when I took off the master cylinder cap. My bad for not checking this sooner, the perils of buying a used bike. Thankfully everything is working properly.

Unfortunately, this discolouration takes place in a relatively short time as the clutch line runs most of it's length down the left side of the engine... how would you feel getting all hot and cold with every ride? To go black, I've seen that a lot, folks have not been sticking to at least the maintenance schedule.... I'd guess yours is 3+ years old.
So, flush and bleed annually at the beginning of the riding season to keep your clutch fluid in top notch shape, and once clean, it's a piece of cake every year, takes much less effort.

Mine wasn't that bad, but it was pretty dark after just a year.


I had been sticking to the book recommended "every other year" interval when after a year, I had to open up the front brake system, so when I was done, I replaced the fluid and bled the front brakes. Speed bleeders made it easy. I figured that because I had an already open can of brake fluid, I may as well do everything else also. So I did the rear - twice - and an ABS flush. By the time I finished, the speed bleeder baggy fluid was a very pale, just barely discolored, amber. Then I did the clutch.


After just a year:

Time spent looking at motorcycles, even Harleys, is never wasted.

Nothing wrong with black DOT4. What should cause one to worry is if the coffee looks like it has creamer added.

Clutch fluid gets pumped every time you shift. It is going to ablate some of the hose and seals. Quit worrying.

I agree, donít worry about it...you flushed it, so now just keep on top of it at least annually.
The clutch goes dark fast compared to the brakes.

If it's black, it means it's way beyond the maintenance schedule. Black is an indicator brake fluid changes were neglected too. Easily fixed, just do it and ride on.

If black DOT4 in the clutch is "way beyond the maintenance schedule" then one must flush the clutch every oil change to stay ahead of the harmless discoloration.

If your clutch works then its fine. Water in the DOT4 will prevent your clutch from fully disengaging. In 9 years of GL1800 kept in enclosed garage and hand washed, the darned clutch fluid failed every 2.5 years like clockwork. It wasn't black, it was chocolate.

Which is why all brake and clutch fluid R&R cycles are 2 years at most.

Ridden wet. Put up hard.

My definition of black is the OP's pic. DOT4 does not go black in two years, it slowly discolours until it's black... never have seen a 2 year old fluid go black, but can be medium dark.
