Clutch spring selection help
Fellow brethren and ladies,
Looking to make the right clutch spring choice and clutch ch plates. The bike info:
2015 Road King
•CABLE CLUTCH
•Dyno tuned
•HD Screamin Eagle tuner
•HD 254E cams
•HD heavy breather
•Thunderheader
The transmission is apart for a spun bearing on the case. Now is the time to decide what to do with the spring and clutch plates
The service writer and I talked and he suggested the HD screamin eagle clutch plates with the screaming eagle clutch spring
I really like the stock clutch pull of the stock spring though. Reading the forum brought up a third option with a trike spring which is in between the two (stock and screamin eagle being the two other choices). So:
STOCK lightest pull spring
TRIKE medium pull spring
SCREAMIN EAGLE heaviest pull apring
I should also mention that my clutch has been slipping for the last year in higher gears when the load is highest or the leverage is highest or however you say that...
The clutch plates are in great shape and no burning on the clutch contact parts. The shop doesn’t even recommend new clutch plates, but I just want to do that while it’s open.
My feeling is to just put a new stock spring in with the mentality that my stock spring has lost some of its rigidity from the beat down I deliver each ride. I have 30,000 very hard miles on it. I do burnouts regularly and continue shifting very hard through the gears often (especially after those burnouts).
For me, the best logic decision is to go with the medium spring (and also what the service writer thinks might suit my needs and preferences of not having a heavier pull SE spring) and the screamin eagle clutch plates.
What do you all think on the situation from you experiences and based on my needs too?!
Thanks in advance

Have you considered leaving the stock spring in and installing a variable pressure clutch. I have them in two bikes that I’ve done big bores on. A 2012 Ultra with a 107 big bore and a 2006 Ultra with a 98 big bore. No clutch slipping problems with either bike and the clutch pull is the same as stock. Give Fuel Moto a call and talk to them about it.

If you like the pull of the stock clutch spring I'd suggest you stay away from the SE spring (which you really don't need anyway). I had the SE clutch plates on mine for awhile and they felt grabby to me. Replaced them with the Barnett 9 plate kevlar ones and an Energy One clutch spring that has approx. 10% more holding power than stock. I am happy with this combo.

I personally wouldn't use SE anything but would not expect a dealer to reccomend anything else.
Barnett or Energy One both make great kits including springs if you want.
My stock clutch burnt out at 23k and I put an Energy One +1 kevlar set in with their heavy duty spring. Besides the clutch pull being a bit harder i couldn't be happier. Clutch has to be forced to slip now. It will not do it on own.

I've used the Harley SE Clutch Spring (P/N: 37951-98) in my current 110 build on my 2015 Limited as well as the one (2010 Heritage) before this. Both builds would be considered moderate IMHO. The pull at the lever changed very little. I haven't had any slipping issues with either, but then again, I'm not inclined to engage in the sorts of antics that might cause me a problem.
