Feuling, Race Series 465 cam chest kit, Oil cooled M8

With 465 Reaper cam (MCS 588026).
FEULING M8 OIL COOLED cam chest kits include all necessary components from top to bottom of the cam chest conveniently packaged in one part number. These combination kits not only ensure each individual part is designed to work and function together but to do so in total harmony. These cam chest 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.

• 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
• 46% 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.

465 CAM - The 465 Reaper is an accelerator, producing solid bottom end performance with substantial gains above 2,800 RPM when compared to stock. This direct bolt-in replacement for M8 engines can be used with stock valve springs, pushrods, lifters and exhaust. Will respond well with slip-on mufflers and or performance 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. This cam will also respond well with increased bore and or compression.

Kits include: FEULING high volume Oil pump, HIGH FLOW billet Cam plate, 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 cam plate.
• 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 M8 front exhaust camshaft lobe flange.

Due to the mass call volume & inquires with requests for the M8 oil pump back cover O-ring/seal groove, Feuling added the groove (5/11/21). Although Feuling's 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 sub-seal O-ring seal, raised sump hole & or sump plug (see M8 PRO TIP below) & looser lifter to lifter bore clearances.

OIL LEVEL NOTE - DO NOT OVERFILL OIL TANK.
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 M8 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.
