For years we have been upgrading the clutches on our “early Evo” Sportsters with what we thought were good results. That was until we got our grubby paws on a Barnett Scorpion Clutch. Now we know what power and modulation feels like. We went with Barnett Scorpion clutch (part #607-30-10084). This kit fits fits the 1986–1990 four-speed Evo Sportster. These clutch assemblies come complete with a billet-aluminum pressure plate, steel inner hub, and specially formulated clutch plates that both increase the surface area and capacity of the clutch. Barnett’s Scorpion clutch also utilizes six coil springs for a smoother and more controllable linear engagement than the competition. Extra spring sets of various tensions are also included, allowing a person to tune the clutch to just what suits you your setup best. The Scorpion clutch can also be run wet or dry in an open or enclosed primary.
We took our bike to Chris Richardson of LA Speed Shop, and he slapped this anodized orange wonder into our bike. Since then we have peeled off a few thousand miles and have found the Scorpion clutch to be a top choice for either stock or modified Sportsters. And we think you will as well. Here’s how we did it.
