Just installed an AMP "power clutch" on my Road Glide. It provides a spring assist when pulling in the clutch. They claim a 50% reduction in effort. Without any way to accurately measure the amount of force needed to release the clutch before + after installation, I'd guess it's more like a 30-40% reduction. Still, with the nerve damage in my arm, worth the price to me. About a 10 minute install. Now my wife wants one for her FLHT. Ordered one for her yesterday.
