I searched and couldn't find any

Thanks, it's an '02 620 Dark.

Clutch reservior was low a few weeks ago and I tried to fill it up, but ended up effing it up completely it seems. Now the clutch doesn't work at all. So I need to bleed

[He Man]

how did you make the beast with two backs up filling the cup?

do a search theres plenty of threads on how to bleed your clutch. youll find a lot of pictorials via google.

I replaced my clutch line recently, as the old one was weeping.  I found the procedure to be time consuming but not particularly difficult.  I started by draining as much of the old fluid out as possible, by putting a piece of 6mm clear tube on the bleed nipple, with the other end in a cup.  I just opened the nipple a quarter turn (8mm spanner) and pumped on the lever until no more fluid came out.  Then I replaced the line (13mm spanner), cleaned the remaining fluid out of the reservoir with a cloth, and gave the bike a bit of a wash where fluid had inevitably spilled when removing the line.

To recharge it, I just filled the reservoir with fresh fluid, opened the nipple, and pumped carefully on the lever (it sprays out of the reservoir if you pump too hard) until fluid started coming out the bleed nipple again.  Then I left it for an hour and made myself a cuppa while I waited for bubbles to work their way out.

The process of bleeding is simple - with the tube on the nipple, pump the lever three or four times and then hold it in against the bar.  This pressurises the system.  Then just crack open the nipple a tiny bit.  fluid and bubbles will come out.  Close the nipple before pressure is lost, and repeat the process until there's no more bubbles.  Check the reservoir level often, and be careful not to spray fluid from the reservoir.  I just put the cap in place loosely while I was bleeding.

With mine, I found that one session of bleeding didn't completely work the air out, so I left the bike overnight with the clutch lever held against the bars using an old pushbike toe strap, and bled it again in the morning.  Now it's as good as new

thanks suzj, I spent a good amount of hours trying this and a few other methods this weekend.....no success. I suck

[corey]

little trick i've learned, if you have any large GLASS bottles, run your hose from your bleeder nipple into one of those. i use a san pellegrino bottle, i like to keep it italian

it just makes it easier.. the bottle doesn't get pulled over by the hose and stuff.

You also want the master reasonably level.

It can take hours.  It took me 1.5 bottles of fluid before finding resistance.  Keep at it.

So out of sheer desperation and frustration I went back at it for a third time two nights again and

WOOOOHHOOOOO!!!!

IT FREAKING WORKED!!!!!!

I started noticing some pressure on the clutch and I was able to ride it around the block, I noticed it was still not all the way right (not enough resistance)

So I tied the clutch to the handle bar for a day and PRESTO!!

It works!!!

I cannot tell you how incredibly rewarding it feels to get this done....THANKS A LOT to all!!

I let mine sit over night as well, then came back to it with a new attitude.  I swear letting it just sit helped the air find its way up to the reservoir, but it was probably just mental.

errrrrrrrrrrrrrrrrrr

let it sit 2 days clamped.. clutch still won't work.

any advice on getting the damn thing to bleed completely?

if you have any way to get to an air compressor,

turns it into a 5 minute job.


if not, just keep at it. try putting your fluid in the freezer, the extra viscosity pulls the bubbles out a bit better

[Howie]

You can also try removing the slave and carefully pushing the piston back in it's bore.  Make sure there is enough room in the reservoir for the returning fluid.

You can pick up a bleeder at Harbor freight for usually $15 I have it and it works fine.
