Its only got 15000 miles. Like I said it only slips in the higher gears when I put a load on it . I have adjusted several times. I'll try and adjust again. Cant believe the plates are worn already. Granted I did buy the bike second hand so not sure how it was ridden. But I do know most of the miles have been highway miles. Long highway miles, from NY to fla and NY to canada a few times.

I have the same problem and it may be the feel of the longer friction Band. The spring on these 96s are soft enough that they have a longer, or feels like a longer friction band. When I let out enough clutch to what feels like the clutch being fully engaged, I add some throttle and get some unexpected clutch slip just before I let the last bit of clutch out. At first I thought it was my tire spinning on sand or something. But as I played with it, I found I wasn’t letting all the clutch out. The clutch almost feels like it has two steps of engagement to me and has taken me a while to get use to this clutch compared to my 2002 RKC. I like the easier pressure of this clutch, but I want a shorter friction band like I had on my 02.

A good compromise spring is the earlier big twin spring that was stock on 04 and earlier big twin bikes. Spring pressure is right in the middle between the stock easy pull on the 07's and the SE spring. My clutch was slipping at full throttle and I went with the VPC clutch and since this setup is centrifugal and the added pressure really doesn't start to come on until after 2500-3000 rpm, clutch application was a little soft off the line. I went with a stock 03 big twin spring with new clutch discs and problem solved. Clutch application off the line is great, and the clutch pull at the handle isn't bad at all. In my case with the VPC adding additional pressure above 2500 rpms, I have no problems at higher speeds either.

What year-model is your bike, as stock clutch specs vary. The SE spring may be overkill in that it will increase lever tension considerably compared to a TC96 spring and you may not need to go this far.
Mine is an '07 with the weakest stock spring in recent HD history and I have no slippage problems even with SE255 cams installed. Thus, I have not been inclined to change the spring. If you are having problems with a stock engine I would suggest double-checking adjustment, at the cable and also at the clutch, and don't use synthetic oil in the primary. Try switching to ATF Type F along with a good adjustment on both ends and your slippage may go away.
Here's a list of some springs with some tension specs. Some who've done the Stage II upgrade (103 with cams) have used the 37871-98A spring and found that it works well.
37882-06 (117 KgF) 2006-88”, 2007 thru 2010-96”
37871-04 (135 KgF) 2004-05 88” and 2010 Limited
37871-98A (145 KgF) 1998-2003
37871-98 is reportedly the same as above except cheaper, but although is no longer available may still be in dealer inventories.
37807-03 (165 KgF) 2007 thru 2010-103 ”Police"
37951-98 (175 KgF) Current SE
