Can't find a reference to see the difference between a Blue Clutch Spring and Yellow Clutch Spring. I see that the Blue one cost more but cannot find any information.

 

Don't know if this is what you're looking for... hope it helps.

37871-04 yellow dot (135 KgF/ 298 lbs/ft) 2004-05 88" and 2010 Limited
37871-98A (145 KgF/ 320 lbs/ft) 1998-2003 Most recommended on forum for touring
37807-03 pink dot (165 KgF/ 364 lbs/ft) 2007 thru 2010-103 "Police"
37951-98 (175 KgF/ 386 lbs/ft) Current SE

 

Thanks, thats a big help.

 

Extremely old thread, just wanted to Bring it up to date, as the information in here is extremely valuable in my opinion.

 

I agree, your listings is the most accurate I've seen. When I did a clutch upgrade (non-hydraulic) did some research and selected the 37807 pink dot that was used on Police Road Kings. This spring provided an upgrade "heaver spring" over yellow dot clutch spring originally installed from the factory.

Another reason I chose this spring as some were stating that the 37951-98 spring was a little too stiff having difficulty engaging clutch. Another person complained of developing a case of carpal tunnel.

I imagine this depends if his / her scoot was driven mostly highway, or city and factor in the strength of the individuals hand. If your scoot has an hydraulic clutch then this doesn't apply, then I would install the heaviest clutch spring available.

Just my two cents,
