Clutch adjustment by changin pushrod length?
Just wondering. It seems like the clutch engages at the end of the lever's travel, as if it is reaching its destination too soon.
Has anyone tried shortening the clutch pushrod beind the slave cylinder so the clutch engages at the middle of the lever's travel?
Not that it makes any difference, just thought a cool tech discussion would be fun

I think he is saying that he doesn't like that the clutch disengages as soon as you touch the lever and that he would like a little play in the lever. I cant say I disagree as it feels like the clutch could be allowed to slip some as it wears.
the problem is that its a hydraulic clutch that is self adjusting to accommodate for wear, so if you trim the rod the clutch will have some play the first time you grab it, but the second time it will be back to normal because the slave cylinder will just not retract as much to make up for the new gap and the fluid in the line will just take up that space that you cut off the pushrod. Same way that as the brake pads wear they just get closer to the rotor and you never feel any difference in the engagement of the brake lever.

Yes, that's what I meant.
I notice when the slave cylinder is mounted on the sprocket cover the actuating rod (pushrod) is so long that the slave cylinder compresses some as it is tightened onto the sprocket cover.
That's why I thought there may be some room to make it shorter, thereby changing the actuation point.

Have you inspected where the pin in the clutch MC engages the clutch lever?
If not then take a look and make sure the pin is fully seated in the recess of the round brass bushing. If it is not it will apply slight constant pressure to the slave and change your engagement point. Don't ask me how I know this...
