hard clutch

[Franny Shoreys]

I have a RT4 build 1064.
is there any way to lighten the pedal force. I have trouble holding down the clutch at a traffic light

If you are using a hydraulic slave, you have the option of replacing the current slave cylinder with one that has a larger bore. Alternatively, you could replace the clutch master cylinder with one that has a smaller bore. If you don't want to mess with the hydraulics, then you could modify the mechanical advantage your clutch pedal has when disengaging the clutch. If none of the above is appealing to you, then you could change your clutch out for one of the current crop of aftermarket dual disc clutches.

If none of this is satisfactory for you, then you are pretty much out of options and stuck with what you have.

I use a hydraulic throw-out bearing and for years it was connected with a 3/4" master cylinder. It was a stiff combination. Last year I replaced the master cylinder with a 5/8" master. What a difference.

I used to have a very heavy single disk clutch, it had an external slave, then I changed to a McCleod dual disk with internal hydraulic throwout bearing. It is much easier on the leg and its a great clutch, it uses a 3/4" master, I may try a 5/8" master as HTM101 recommends

First off....You should never sit for an extended time with your foot on the clutch. First thing it does is destroy the thrust face bearing on the crankshaft, secondly the throw-out bearing is going to fail. Other than that the advice given above is good.

I have a McLeod dual disk clutch, and the pedal pressure is light. Even so, I usually put it in neutral at a traffic light.

Wilwood also makes a Girling style 11/16 master cylinder. That it what I typically use with an internal hydraulic throw out bearing. I have found that 5/8 sometimes does not move enough volume to fully disengage the clutch.

I installed this in mine and it works great , a little above 11/16 .6875 too .700 bore

did you have any issues with clutch disengagement? I have the same problem and couldn't find a slave clutch that fits with a 7/8bore. I did notice the pedal has a hole 1 inch higher that would help mechanical advantage but that requires the master to be moved up to keep alignment.

I didn't. I have a 5/8" stroke at the HTOB.
