Clutch Release Point 5th Gen

Having more stroke is always a good thing. Back on track, mhz does the lever pull seem to have a feel to where you can tell it's against some resists? letting you know it's moving. Clutches action here are almost a tricky feel to em, some are so soft you can't tell until you start letting the lever out what's going on. mine acts like they should. By having a little action taking up the slop when disengaging, then you can tell its doing it's job with a little resistance, my clutch action is about mid point when letting it out and totally engaged just before I let go, so I'd like to think mines pretty much the way it should be. I mean it acts good for me. Knock on wood chasing Murphy away..

 

Just changed the fluid, which was pretty dark. The clutch still engauges late.

 

Hey, I'm stealing this thread a bit. Had a look at the bike today, it's in winter storage with the inlaws (don't even get me started on the "are you really gonna ride it NOW, you should wait 'til April, or May, or never...)
The thing is that since I put it in storage in October when I did an oil change I haven't touched anything other that the electrical with installing heated grips and a voltmeter/USB-thingy. Today I started it and put it in first gear, engine stalls. Hm, silly of me to leave the side stand down, up with it, start the engine and do it again, same thing. With the clutch fully pulled, I can't move the bike and then I think about it and realize that I haven't felt the clutch really. Get it in neutral again and start the engine, pull the clutch a couple of times bit it really doesn't feel like it's moving the clutch, and when I put it in gear it stalls.
Again, neutral, let the engine go for a while and get to 70-80 degrees centigrade, pull the clutch and I get a slight feeling of something happening, put it in gear, the bike starts to move. So I roll it on the gravel at the inlavs, which is pretty much mud but what the hell. After a while I can get the clutch disengaged when REALLY pulling the cluch fully, but the balancing point, or what that's called in english, is a mm out from the hadle.

Any ideas? Can too much engine oil cause this? Is it the cluch somehow? The reservoir is full, or at least the window says so and when I was pulling the lever it didn't go down so there shouldn't be any leakage, which I didn't really look for, silly me. Could it be that it somehow ha gotten air into the system over winter?

Really bummed right now :/

I'd suggest the most likely thing is you have air in the clutch line that needs to be purged out. When you work the lever, can you feel the resistance of the clutch springs?

First step, buy some clean DOT4 fluid, syringe out the reservoir, top it off with clean fluid, crack the bleed nipple at the slave cylinder and start bleeding. Keep at it until you get a good solid feel, topping up as needed.

 

I started to feel som resistance after a while but at first it was "blank"
Thanks, I'll have a look at how you bleed hydraulics, never done it before

 

Get a couple of feet of clear plastic tubing that is a snug fit on the bleed nipple. Put a ring spanner on the nipple then fit the tube. Put the end of the tube in catch bottle bucket etc.

Take the lid off the master and remove the rubber bellows. I suggest you take out old fluid and any residual goo from there. Now top up with fresh fluid.

Squeeze the lever to pressurise the line, while holding lever loosen the bleed nipple to release the fluid. Important: now shut the nipple before releasing the lever. Repeat as needed until fresh clean fluid flows out the nipple. Hopefully you'll push any air out too. Don't let the reservoir level drop so far that you suck in air.

When done, tighten the nipple, top off the reservoir and refit the bellows and cap.

Don't leave spilled fluid on surfaces as it can lift paint.

Was there any evidence of leakage from the system? Mostly that'd be seen at fittings, or where there are seals, rarely a line fault.
Terry Smith is spot-on with bleeding procedure. Can be done by oneself, easier with two people, but accurate communication of when to do what is imperative.

 

I shouldn't do it with the wife then
No apparent leaks, but I didn't really look either, considering that the level didn't drop in the window of the reservoir it shouldn't be leaking I THINK. Do you have any idea of the dimension of the hose needed (the bike's some 60 miles from here so I can't check myself)

Thanks!

 

The tube I use has an id of about 5mm.

Other tasks that one should avoid with one's wife include wallpapering, putting up a tent on a windy day and learning to drive. In my experience only, of course.

Clutch bleeding is a one person job. Left hand on the clutch lever, right hand on the spanner at the bleed.
