As far as cable I thought that with 1 full turn you will be more far from the bar than with a half turn, that's what I want to do on mine.

To day Today I rode in sport mode most of the time, even through villages, and I got used to it quite well. I'm starting to get used to this throttle grip, and I'm sure that once I have a better riding position,

There are actually a couple offerings by a couple companies. It does exactly what it says. Takes the edge off, much easier. It's just a bigger slave cylinder to provide more assist. There is one in there, replace it, bleed it. Super easy. I don't like the fact you can't adjust the friction zone on the hydro... But honestly, I don't get why people don't like them. No adjustment needed, feel fantastic, 100% consistent. I like hers on the trike. I've been round and round about this one... So many think different... 1 full turn out moves zone closer to bar... 1/2 turn out further out. I only stay within spec on adjustment, but full spec out. The adjuster screw... Go thru the procedure, adjuster screw full turn out, lock it down.

Somebody explained once it's not actually moving zone, it's changing effort applied to move it sooner. I didn't get it, can't explain it, don't exactly care.... Hate 1/2 turn out, love full turn out.

Now the only question is... Can it be tuned out, softened. We wouldn't tune throttle responce in the travel range, but first 5%, crack open.

Anyone got a tune... Tried to improve it?

Another solution to the stiffness of the clutch problem is the Rekluse TorqDrive clutch. It adds four plates to the clutch, which allows the use of much lighter springs, which they provide. With the lightest springs, white stripe, the clutch will still handle 135 ft/lb of engine torque. If you used this in conjunction with the other methods to reduce the pull, you could get to a point where it would be significantly reduced. Rekluse makes their own replacement hydraulic slave cylinder for use with their clutch. I didn't see any replacement ramps for cable clutches.

Here is the cam chest on the 117" '25 Softails.



Here is the cam chest on the '25 121 ci. VVT.



The parts that enable VVT are the variable drive gear for the cam, part 14, the cam phaser, part 24, and the VVT actuator solenoid, part 29. These are missing in the 117" and 121" HO models. The advantage to VVT is a much flatter torque curve, although the over all power seems to be less.
Well that's just ghey. Why bother with appearances. .. Clearly they don't have to? I just assumed....

Yeah, it looks like they even go so far as to run the wire for the actuator solenoid. It would appear that eventually they mean to offer it in all models or in selected Softail models.

Thanks for your responses,
I will go this way for my wife's Freewheeler, and as you I like a lot the hydro clutch, it's smooth and feel always the same, I wouls like to have one on my LRS...
and also for the advice to aadjust the friction zone

I ordered the Mueller kit. 2 of them. I don't "need" an easier clutch, but if it improves feel and adjustment and get rid of plastic... Fine.

The part linked above on ebay by parts giant.... A lot will say M8... But you go and it's not the right part. Says won't fit. I looked all over... Seems the 2.0 is for M8, and some listing won't specifically say 2.0 or M8. I They all use the same photo for all M8 and everything before M8. Makes it confusing to buy with confidence it's right.

Anyhoo, Law Abiding Biker hawks them a lot and they have the specific ones listed so that's what I got. And it seems the M8 2.0 comes with the clutch cable replacement tensioner all together.
