RACE SERIES CAMCHEST KIT W/ REAPER 472 - Chain Drive, Fits Milwaukee Eight 17-22 Oil Cooled Engines

  • FEULING M-Eight OIL COOLED camchest kits include all necessary components from top to bottom of the camchest conveniently packaged under 1 part #. These combination kits not only ensure each individual part is designed to work and function together but to do so in total harmony. These camchest kits take the guess work out of the ordering process and guarantees the engine builder maximum reliability, peak performance and the coolest engine and oil temperatures obtainable.

    Available in HP+ or RACE SERIES kits
    Quieter and smoother engine operation
    Increase oil pressure, scavenge volume and engine oil flow
    27% more pressure and scavenge gear volume over stock
    42% more scavenge volume with port sizing, matched passages and holes to the engine case
    68% more oil volume to the crankshaft and connecting rod bearing
    15-25 degree cooler engine temperatures
    15-30 degree cooler oil temperatures
    10-30 more PSI of oil pressure
    Reduces wet sumping, blow by and oily air cleaners
    Magnets in oil pump to help protect gears and pressure relief valve
    Test results show 2 HP gain and 2 ft/lbs of TQ gain to the rear wheel on Milwaukee Eight
    NOTE: FEULING test results show a 50% reduction of engine sump oil level.

    -HP+ SERIES Kits includes a billet 6061 aluminum high volume oil pump, FEULING HIGH FLOW camplate, HP+ Hydraulic roller lifters and cam installation kit.

    472 Camchest kits are available in FEULING HP+ and RACE SERIES combinations with chain drive REAPER camshafts.

    The 472 Reaper is a great all-around camshaft and Feulings go to for 4 1/2 stroke 114 - 117 looking for a little more than our 465 grind and wanting a bolt-in. The 472 has a great bottom end with substantial gains above 2,900 RPM when compared to stock. Responds very well to increased bore and or compression, exhaust system and air cleaner. Use of performance valve-springs is not required but may result in a quieter, smoother running valve-train See Feuling #1107 or #1108.

    Kits include: FEULING high volume Oil pump, HIGH FLOW billet Camplate, REAPER Series Camshaft, hydraulic roller lifters, fixed length pushrods, TIMKEN/KOYO cam bearing, rocker arm studs and nuts, gaskets, O-rings, ARP cam/crank fasteners, washers, moly lube and LOCTITE.

    -RACE SERIES Kits include a RACE SERIES oiling system: billet 7075 oil pump, RACE SERIES lifters, HIGH FLOW billet 7075 aluminum camplate.
    Billet 7075 aluminum oil pump which is 50% harder and stronger than the factory pump holding tighter tolerances under temperature, deeper scavenge kidneys over HP+ oil pump.
    Deeper scavenge kidney ports over the HP+ series for even more scavenge flow volume
    RACE SERIES hydraulic lifters have a full .200 of total travel designed with a slower bleed down rate to handle heavy valve spring pressures, increase engine RPM before valve float and feature increased roller clearance for steep ramped camshafts and clearance for the Milwaukee Eight front exhaust camshaft lobe flange.

    Due to the mass call volume & inquires with requests for the M-Eight oil pump back cover O-ring/seal groove, weve added the groove! (5/11/21). Although Feulings in house testing on healthy engines did not show a benefit. The O-ring may have potential benefits in certain circumstances such as engines with higher cylinder leak down, poor subseal O-ring seal, raised sump hole & or sump plug (see M8 PRO TIP below) & looser lifter to lifter bore clearances.

    It is important to get the correct hot oil level in your bike. Feuling recommends running the oil level 90%-99% full when hot.

    Note: The M-Eight oil pick up port is on the right side of the engine. Letting the bike idle or warm up on the kickstand will naturally fill the engine case and skew the oil level in the tank.

    We recommend the following steps to achieve proper oil level:
    1. Check cold oil level.
    2. Ride the bike until operating temperature is reached.
    3. Shut the bike off while still in the upright position. (This insures an accurate reading)
    4. Once the bike is on the kickstand check oil level.
    5. Add or remove oil as needed.
