The first picture shows the standard factory cable bracket which is removed when installing the latest version of the Rainey slave cylinder.
This second picture shows the slave cylinder top U bracket hooked up to the end of the clutch actuation arm.
This next picture shows the Slave cylinder installed to the hydraulic line and the actuation lever, and adjusted to the 2-3mm distance as recommended in the Rainey video on YouTube. As you can see in this latest version there is no longer any cable, it is a solid rod with threads at the U bracket. The main adjustment is made by loosening the two 13mm nuts above and below the gimble. I wound up with 10mm of threaded barrel above the top nut. I chose to leave the U bracket hard up against the solid portion of the rod for stability. You should use two or three zip ties on your hydraulic line around the bottom frame of the bike to keep the slave cylinder in place with no movement front to rear.
This last picture shows a view from the side of the U bracket hooked up to the actuation arm at the top. I included this picture to show that the actuation arm is attached on a spline shaft, and it could be removed and moved one or two splines clockwise to eliminate so much of the threaded barrel of the slave cylinder above the gimble and locking nut. I felt that was unnecessary.
For newbies that have never worked on your nine....
The side case you remove is three 4mm Allen head caps.
The large nut that tightens the hydraulic line to the slave cylinder is 14mm
The two adjusting nuts that raise/lower the slave cylinder are 13mm
The three bolts you must remove to take the factory bracket and braided standard cable off are 8mm and 10mm
The bleeder at the slave cylinder is 7mm
The two sleeves to tighten the line to the end fittings are 13mm
Hope that helps someone with their installation, is 65 degrees here......I'm going riding!
