For those who are seeking Harley clutch springs, see list below.

37882-06 blue dot (117 KgF/258 lbs/ft) 2006-88", 2007 thru 2010-96"
37871-04 yellow dot (135 KgF/ 298 lbs/ft) 2004-05 88" and 2010 Limited

37807-03 pink dot (165 KgF/ 364 lbs/ft) 2007 thru 2010-103 "Police"
37951-98 (175 KgF/ 386 lbs/ft) Current SE

Note, if your scoot doesn't have a hydraulic clutch the SE Screaming Eagle 37951-98 are known to provide a workout in traffic situations and in some cases may cause carpel tunnel in left hand.

I chose the pink dot/or stripe 37807-03 (happy medium) like the feel and pull engaging clutch. This setup with ALTO Carbonite clutch kit are used extensively in Police Bike applications, the pink stripe clutch spring provides a 18% increase in clutch pressure than 37871-04 yellow dot/or stripe clutch spring that was used on my 2012 road king FLHR.
