Bolt-on kit  to enhance the performance of an original equipment clutch.    http://cyrilhuzeblog.com/2013/04/12/harness-high-performance-power-with-new-screamin-eagle-variable-pressure-clutch/

You have a hydraulic clutch on your CVO,  these kits are made to enhance the standard cable operated clutch.

The Variable Pressure Clutch kit will work on cable or hydraulic clutch bikes.  This same product has been available from an aftermarket company for many years; it appears Harley has either bought the product from them or stole their idea.

I've used the aim-tamachi version of this product for about 5 years (hydraulic clutch bike).  I'm not sure how much it actually helps - I know I don't get any clutch slip and I "believe" the clutch lever effort is reduced somewhat.  But I know it looks cool in there!!

I used to run the AIM VP-70T Variable Pressure Clutch. It does reduce the the clutch lever pull effort - for awhile - until the relatively soft 6061 aluminum its made of wears down at the fulcrum points, reducing its effectiveness.

There is a better and less expensive way  to reduce the clutch lever pull effort of either a cable-operated clutch, or a hydraulic clutch like I have on my bike. It's called the ClutchWIZ, designed by a member here, Mr. Wizard, but not sold by him. It's made of 7075 aluminum, which is much harder than 6061 aluminum and doesn't wear down like 6061 aluminum does. Details about the ClutchWIZ can be found at http://clutchwiz.com.

We measured my clutch lever pull effort with the ClutchWIZ at 9.8 lbs... considerably less than the stock pull effort. I can pull my clutch lever with two fingers easily.

I have written about the VPC and the premature wear, and the ClutchWIZ that I run now, in my mods thread here: http://www.cvoharley.com/smf/index.php?topic=66236.480

On a CVO, due to the torque created, you need a heavier clutch spring with the ClutchWIZ to prevent slippage under heavy acceleration. Ironically, AIM (manufacturer of the VPC) markets a 480 lb clutch spring, which is what I use. I also installed an extra plate clutch pack from Energy One to eliminate all clutch slippage. Barnett also makes an extra plate clutch pack.
