Clutch actuation issues

Have owned my 2001 GL1800A for almost 11 years now. Been doing very regular maintenance on it since I bought it in 2006, including bleeding/flushing my clutch fluid every other year.
Heres my problem:
When I pull my clutch lever in fully, then shift into gear, or when shifting to neutral, or when upshifting, it feels like my clutch isn't fully dis-engaging. Many time when accelerating up through the gears, the gears almost grind, as if I havent fully pulled the clutch in.
Now, if I bleed/flush the clutch, it seems to be better for a while, then the problem comes back.

Whats the fix? Are any of the rubber hydraulic hoses breaking down/expanding? I dont know of any other adjustment to the clutch system, so I'm open to suggestions!

Now, if I bleed/flush the brakes, it seems to be better for a while, then the problem comes back.

Maybe you mean't to say "...if I bleed/flush the CLUTCH..."? Not too sure how servicing the brakes would affect the clutch.

At any rate, I had the very same problem on a Yamaha Venture. It was odd because I'm sure I had serviced the fluid when I replaced the slave cylinder on it the year before. I eventually changed the DOT 3 hydraulic clutch fluid out for DOT 5.1 and that "fixed" the issue.

Thx, corrected that long day...

I have been using DOT 4 Synthetic fluid for may years in all of my vehicles. Never heard of using DOT 5.1. Just read up on the differences between dot 4 and dot 5.1... interesting.. Apparently, DOT 4 absorbs moisture faster than DOT 3 and thus needs to be changed sooner... Could that be contributing? Not sure, as my clutch only seems to improve for a week or so after changing the fluid, and its only a marginal improvement.

I also have Kuryakyn ISO grips on my bike. Obviously, thicker than stock grips... wonder if that could be contributing to having less room for travel when pulling in clutch lever? I bought a set of Show Chrome heated grips that I still need to install. Wonder if they are the same diameter or ????

Good point! I replaced this brass bushing several years back due to this issue, and did see some improvement.

Thinking.... is there anything at the clutch slave itself that could wear out? A push rod that is actuated by the slave to the clutch basket that could be worn?

I'm looking at the clutch slave here:

Could the slave unit be worn out?

How many miles on the bike? I'm at 150k and having none of those issues. Buddy of mine was having them on his bike and replaced that bushing and all was well.

I think that would be premature but things do happen sometimes. I just replaced a final drive on a guys bike that only had 60k on it. Good luck.

Good stuff posted above, I would add that you be sure the little hole in the reservoir is not plugged preventing proper fluid return after actuation. I found one once that had Some crud in it. That prevented full stroke of the lever. Clutch wasn't fully disengaging or engaging. I disassembled the master to clean it out, and just put it all back together again. Worked perfect, still is.
