Race Series Twin Cooled Camchest Kits / Milwaukee-Eight

Twin Cooled Race Series camchest kits, in a choice of two Reaper grinds.

Both variants are complete Race Series camchests for a Twin Cooled Harley-Davidson Milwaukee-Eight. What separates them is the camshaft, a 487 or a 508 Reaper grind, so the choice is about the power delivery you want rather than about fitment.

Feuling reports these kits deliver quieter and smoother engine operation, increased oil pressure, scavenge volume and oil flow, 15 to 35 degrees cooler engine temperatures, 15 to 30 degrees cooler oil temperatures and 15 to 30 psi more oil pressure, while eliminating wet sumping, blowby and oily air cleaners.
