not enough clutch free play

I have been lovin my RC lately riding it to work in the early CT. spring.

One thing I don't like.

The clutch engages / disengages with small angles changes in the lever just off the stop. The engagement is smooth and progressive enough, it is just that the active area is at the beginning of the lever movement.

Anyone know how to make the clutch engage more near the middle of the movement?

Several times I have almost dumped the clutch thinking the bike was not in gear and then you get a moment where you are happy your reflex was to pull the clutch in and not let it out.. like immediately after a good rev and the motor is spinning too fast for a gentle pull away.

Well the clutch is hydraulic, so there's no adjustment like with a cable clutch.
And they do have a hair trigger feel that takes getting used to.
Just in case, have you bled your clutch line to ensure there's no air that could cause problems?

+1

RC has a very different pressure point to engage/disengage the clutch and will take some time to get aquainted.

Don't see it as a negative, just different.

Have you ever ridden a bike with a hydraulic clutch before the RC??

How about adjusting the position of your lever????? Depending on the type of lever you are using you should be able to move the position so it DOES engage or dis engage in a different position!

Yeah, I have hydraulic controls on my other scooters. The RC clutch is nice and progressive, just don't like the actuation point right as you grab the lever. Nice for fanning the clutch thru the gears but can be disconcerting at a stop when begin to think you are in neutral.

No air in the line, that would make it actuate later I would think as the air would compress first.

I've been thinking about taking a few thou off the clutch actuator push rod, I have to take a look at the microfiche. I don't see how to easily correct it at the lever and my lever is usually adjuster full close to the bar.

Perhaps a shorter or aftermarket lever would help, but I am skeptical of that as the pivot points would most likely be near the same.

Nobody else had a desire to change this ??

With air in the line, the air would compress so the slave cylinder wouldn't be pushed far enough in the cylinder.
That would make for less travel, and appear to have a short engagement point.

if you shave the push rod it will just make the plunger move further the first time, it still is only going to retract a certain amount, imagine its like your brake calipers when your pads wear....

What if you took some material off of the clutch lifter rod, wouldn't that have a better desired effect you are looking for?

The only way to change it would be to get a different size piston in either the slave or master cylinder.
