High perf clutch spring
The 103 KIT includes a high perf clutch spring. I talked to the techs about this. They said if I'm an easy rider (not stomping on it) I could get by without the hi perf spring but to watch for any clutch slippage. If I have them put it in, then the clutch control will be noticiably stiffer. Any thoughts for you "pros" on whether I should bite the bullet, go with the upgraded spring and live with a stiffer clutch pull but avoid burning out the clutch?

my local shop did my 103 upgrade last winter for $1440. Included SE255 cams and 103 jugs/pistons, etc. New bearings, and dyno tune after I put about 500 miles on the engine. You can do the compression releases, but I think if you go with the SE compensator, you'll never need them. I had to have the SE compensator installed on mine before starting issues finally went away. Compression releases would probably do the same, but they burn your fingers...the SE compesator does not!!! and the cost is probably close to the same.

First 103 build I chose not to change out the plates. I could feel the clutch slip, also am not one for a hard take off. The only time I noticed it was on a mostly on an uphill grade when I was taking off riding 2 up.
So I opted for the clutch plate on my next 103 build. The nice part was no charge to change the plates while they were changing the springs on the second build

Going with the perf spring
Thanks guys. I tried a bike with the stronger spring and yes, it's noticiably stiffer but no where near as stiff as my 03 RKC was. I pulled on a couple of used bike clutches to compare and I'f forgotten just how stiff they were!

SCREAMIN' EAGLE BIG TWIN COMPENSATOR
This premium compensator has been engineered with heavier springs and increased travel to support the high torque output associated with high compression race and large displacement engines. Designed to support up to 7 times the energy absorption capacity of the Original Equipment compensator, this unit helps protect the engine and driveline components during harsh drag race launches. The perfect addition to a complete performance upgrade, and it complements the installation of the Screamin' Eagle Performance Clutch Hub PIN 37976-08. Fits '06-later Dyna, '07-later Softail (except FXCW. FXCWC and FXSTSSE3), and '07-later Touring models. Original Equipment on Trike models.

When I had my '07 Ultra I did the 103 kit and cams. I had the Arlen Ness Big Sucker A/C, and Kerker slip ons for the exhaust. I installed a PC 111, but was not happy with it until I had the bike dynoed. The bike when from 62.94 HP to 84.31 HP, and 74.25 Tq to 101.78 Tq. I have not done any thing to my '08 Ultra besides Arlen Ness Big Sucker and SE pipes with a Harley download. I think I have enough power for now, but I love getting 50 MPG. I still have the cams, piston, & cylinders that were on my '07, but just can't bring myself to put them in yet and get that 35 MPG.

The 255's with the 103 cu in motor is alright....the torque starts just off idle. It's great for cruising and still have some performance. Instead of a dyno tune I would go to the Master Tune TTS . Check out the threads in HD forums ..... more fun less expensive.

Huh? You still have to dyno tune after a TTS install and how is it less expensive?
