Just did a 103 upgrade with SE 255 cams on my 2011 Softail. The kit included a high performance clutch spring, which I'm finding wears my hand out on long rides.

I'm looking at installing the HD Variable Pressure Clutch (P/N 37000121), but I can't tell which clutch spring I should use with that VPC.

For the 103 engine with the Variable Pressure Clutch, should I use the stock clutch spring or the heavier SE Spring (P/N 37951-98)?

Anyone have any recent experience with these?

Thanks in advance.

 

From HD's website:

"Screamin' EagleŽ Variable Pressure Clutch
Get more performance from the Original Equipment clutch. The Screamin' EagleŽ Variable Pressure Clutch is designed to help put the added power from a Screamin' EagleŽ Stage Kit to the pavement. This bolt-on kit harnesses the centrifugal force of spinning weights to increase the clutch capacity as engine speed increases. The mechanism applies increasing pressure to the stock clutch pressure plate as rpm rises. The result? High torque-handling capabilities without increasing clutch lever effort at idle. The Variable Pressure Clutch also provides smoother clutch disengagement at lower speed. Kit fits behind most stock derby covers with no modifications."
