A few years ago,
big builder Kevin Boyle
was vacationing in New Orleans. By chance, he met a guy
named Mark Aldren. Both had an interest in motorcycles.
bought a couple of stock Sportsters, and he pretty much
rode the wheels off them. It was fun. But maybe it was
becoming a bit boring. Then happenstance intervened again.
Mark ran into Kevin at a big bike show. They started talking
about custom bikes. One thing led to another, and Boyle
was given the task of building a ground-up bagger for Mark.
That, of course, is the bike in front of you.
and that's why the bike was built herky-jerky style. When the
bucks ran out, Kevin would push the machine into a corner
and work on other projects until Mark recharged his build
account. As a result of the project’s start-stop approach, it
took a year and a half to complete, but no one is complaining.
The big FL is stunning. Here’s how it went together.
Kevin located a clean 2005 Police Road King. Once he
had it in his shop, he immediately stripped it to the bare
bones. The Twin Cam went on his workbench. Boyle went
completely through it. The basics include a 98" big-bore kit
from Revolution Performance. Included are Wiseco 10.5:1
pistons, big-bore cylinders, piston rings, wrist pins, and
gaskets. According to Revolution Performance: “We utilize
Millennium Technologies’ Nickel Silicon Carbide (NSC)
cylinder plating process, which forms an extremely hard,
extremely durable barrier with less friction, improved heat
transfer, less weight, and ultimately more horsepower.” Fair
enough, they’re high-quality pieces (so is the rest of the
build). That took care of the displacement (the cases, crank,
and rods are blueprinted stock pieces). Upstairs, though,
