clutch spring plates
any one know the colour coding on the spring plates. doing engine to 107 I think I have one from my old 2003 electra glide in my 2009 ultra looking through my collection of parts I found 3 spring plates, I did write on one that came with 255 kit 178 kgf plate no colour marks on it, way too stiff . I have one with a yellow dot on it, another with looks like a spec of yellow but not too sure the one in my bike may have red dot but wont know till I yank cover off I think the yellow one may be about 130 kgf one of them should be 117 kgf that came on the bike

I have a 12 FLHTK, doing the compensator right now, stock spring on my bike has 3 yellow markings on it, I believe it’s considered an “Easy Pull” if my information is correct. Personally if I was doing a 107 I think I would go with a new 37951-98 spring.

did some digging in old posts
37882-06 (117 KgF) 2006-88”, 2007 thru 2010-96”
37871-04 (135 KgF) 2004-05 88” and 2010 Limited yellow
37871-98A (145 KgF) 1998-2003 may be yellow
37871-98 is reportedly the same as above except cheaper, but although is no longer available may still be in dealer inventories. guessing yellow
37807-03 (165 KgF) 2007 thru 2010-103 ”Police" pink
37951-98 (175 KgF) Current SE no colour
jdw1 I have one of those 175kgf springs, way too stiff without a hydraulic clutch, ok on hyw but if your in town pulling it in constantly its a killer. Ill try one of my yellow ones 135kgf . I had it in before on a 103 kit with 255 cams and mva heads- terrible combo dydnoed at 100 tq and 98 hp hoping my new set up will be close to 120-120
so since I have 2 yellows that probably means I put the 117 kgf back in the bike and one I wrote on 175 kgf hanging on my wall
so looks like Ill pull off primary cover see if there is any dots on it and stick a yellow one in for now to handle the 107 kit. Ill get an aim variable clutch later.. wife thinks ive blown enough money on the motor so far about 3 grand ,
