ChicagoHD stopped giving the 20% discount for the crate motor. It's like a $150 discount now on crate motors. That was posted a few pages back. Or maybe it was on v-twinforums.
Regardless, you could get the same discount on alot of the components I listed. Though the quality of the components just isn't as great as the aftermarket stuff. For example, you could use the SE 4.625" crank and rods assembly for $1000, or the S&S that's been trued and welded at Darkhorse with beefy H-Beam Con Rods for $2100 More expensive for the parts, yes. But more likely to hold up too.
Here's sourcing most of the components from the Screaming Eagle catalog, and applying a 20% discount.
