I have an S&S 107" in my 1990 Evo and am still using the original stock clutch, with a Barnett spring. No problems and I don't see the 'need' to change. A TC clutch should be more than man enough! However I have been promised improved gear changes with a Barnett extra plate kit and just bought a kevlar set. Got mine off Ebay, where there is a vendor with a LOT of sales and great prices.

So far I'm looking at just upgrading my clutch frictions and steels. After talking to Barnett tech, they would recommend moving up to the Scorpion clutch first. Which uses Carbon Fiber frictions. Next down from that would be the Carbon Fiber kit, for a touring bike. The carbon fibers work best with high heat. And they also recommend non-synthetic ATF type F fluid, especially B&M Trick Shift Trans Fluid.
The SE Clutch Spring is 380lbs, which is what I have now, what are the next high clutch springs available?

Energy One is the way to go. Great folks to deal with and they have a selection of different springs. Check out their website and give them a call. This is the only clutch we install at our shop and have never had a problem. It held up on my 100HP Evo FXLR without any problems with a 10% spring. Just my opinion, but it doesn't hurt to call. I know one will go in my Tri when the stocker goes.

Another plug for Energy One clutch. I have installed 2 of them on different bikes with great results. They replaced the stock clutches on my 2004 Sportster, and my wife's 2006 Sporster. Both were 1200's and the stock spring plate on each of them disentegrated around 18k miles. The Energy One extra plate kit eliminates the spring plate. Not an issue with late model BT's but I still recommend them. Also, have you considered the VPM upgrade instead of going with the hand busting heavy clutch springs? A bit pricey,but I hear they lock up good without increasing lever pull.

Yes looking at that too. May add if I see slipping at higher rpms. It doesn't do much low end. Maybe a new clutch with more surface area is the way to go when all said and done.
Right now I'm thinking I'll go with my SE spring I have and either the Barnett Carbon Fiber kit #307-30-20013 (if I can get a good price) or the Alto Carbonite #095750NC which I've found very reasonable, and if Alto Carbonite is good enough for Eric Buell, it's good enough for me. Under $145 either way.

I don't feel this build requires a high performance clutch.
I've ordered the Alto Carbonite Hi-Performance Powerpak Kit #095750NC and the Barnett Spring conversion kit #511-30-10004. This should get me in the area of the SE clutch hub kit #37976-08A, which is good up to 160ft-lbs per the HD website.
The Alto Carbonite Kit has 10 fictions and 9 steels, so there is some added surface there about 10%.
In reference, the SE Performance Clutch Friction Disc Kit 37980-10, has 9 frictions, 8 steels, a SE heavy spring and is also an OEM replaceable kit.
