FEULING DESIRE
SKILL LEVEL // MODERATE
ROAD KING CAM ASSEMBLY AND BASSANI PIPE SWAP

urability is key on long rides, especially when you own a bagger like this 2000 Harley-Davidson Road King. Feuling’s high-flow oil pump and camplate should help keep this motor cooler on those long, hot runs in the desert. Cycle Doctor in Costa Mesa, California, spent a day walking us through the changeover.
1 p Most of what we’re doing focuses on a cam assembly
swap to modernize the lower end while upgrading oil flow. This Feuling billet cam plate increases engine oil flow and volume by enlarging critical oil passages and the oil pump reservoirs. It’s blueprinted and matched to the Feuling oil pump to take full advantage of the increased volume from the Feuling oil pump we’ll also be adding to the mix (it only works with their pump). It comes with the bearing retainer plate and hardware.
3 2 p Joining the new plate is Kuryakyn’s Wild Things TC-2U
performance cam set. The “U” series cams are designed to upgrade earlier Twin Cams to work with later (’06 and ’07) oil pumps. It’s a bolt-in performance set intended for 88- to 103-inch motors.

p Feuling also supplied us with new .120-inch-thick
pushrods. They’re stiffer and more rigid than stock rods for increased stiffness valve-train stability. Made from 7/16-inch chrome-moly steel tube, the Feuling pushrods use a minimal adjustment parameter eliminating the flex and loss of valve-train stability problems associated with some adjustable pushrods. They’re also meant for use with performance engines that use larger lift camshafts and high spring pressures while maintaining proper and critical oil flow to valves, springs, rockers, shafts, and valve guides. They can be used with hydraulic or solid lifters. 4. Since we were using Feuling rods, we thought we’d give their standard size racing lifters a try. Like the rods, they’re intended for use with large lift camshafts and higher spring pressures. These lifters are designed to work in conjunction with the Feuling oil pumps or other high-volume oil pump.

5. Feuling’s oil pump for Twin Cam engines (part #7060, $425) is a Billet 6061 aluminum high-volume unit that increases oil pressure 20 percent for cooler oil and engine temperatures and eliminates blowby and wet sumping due to its 30-percent more scavenge (return) volume.
