Unhappy Light pull clutch

I had neck surgery and now have nerve damage that effects left hand grip. I have a 2006 SG with a S&S 116 that makes 120+ HP and torque. I am running an S&S non hydraulic clutch. Can no longer pull clutch in. Need to reduce clutch lever pull without getting cultch slippage. Help!!!

You are asking for the best of both worlds, we do not recommend the easy pull ramps because it takes away from the amount of travel. Going to a lighter diaphragm spring will help but then you run into slipping. Have you buy chance tried a hydraulic clutch? I personally am not a fan but it may be something to consider. Go to a Harley dealer and pull a couple and see if it is something you can live with. Harley Hydraulic clutch's use an 11/16 bore master cylinder, which from what we've found work best as far as disengagement. They may be a little tougher to pull then some of after market 5/8 or smaller bores but they work. From our experience the smaller bore's do not get enough fluid and therefore not enough travel. I believe there are some other systems out there for easy pull but I have no experience with them so hopefully someone else can chime in.
Here is another option, we use it for racing but it may work for you. You will still have to use the clutch for first gear but after that no clutch and you are golden.Click on the link and the scroll to the bottom where you will find ignition kill shift drums.

Let me know if you would like to give one a try.

Thanks for the info but my current pull with the S&S race clutch is in the 25 pound range and i need it to be no more than 15 pounds. The race shifter is not an option because I can't pull it in at all so starts would be impossible. There must be another option out there for people with diminished grip strength. Anyone have any experience with Clutch Wiz or the MRC clutch? These products advertise reduced clutch pull on performance clutches.

Find an E Z pull, install and the pull is much easier....

Foot clutch. Most likely with that motor you'll never get the pull light enough without the clutch slipping, you are trying to reduce the pull by 40%. Like Mark said that would mean a reduction in pushrod travel by 40%. Probably not gonna work.

There are various devices available that reduce the need for a strong spring, such as the AIM VPC, which uses centrifugal weights to increase pressure as primary speed increases.

You would probably be better off going back to a stock clutch and beef it up a little.. I have a 2000 fxdx 116, that has early 21 deg ramps for the actuator, stock plate count, barnett carbon fiber, easy boy arm and Barnett heavy spring. The pull is about the same as stock..

Diaphragm clutches are nice as they are "constant pull" the SnS clutch is 6 coil springs, so when you pull the clutch in the pill gets progressively heavier. Diaphragm springs don't do this.. Thier pull is more or less constant once the pressure plate starts to move..
