Feuling Race Series Camchest Kit Water Cooled M8

FEULING M8 WATER 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. • RACE SERIES kit • Quieter and smoother engine operation • Increase oil pressure, scavenge volume and engine oil flow • 30% more pressure gear volume over stock • 53% more 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. Due to the mass call volume & inquires with requests for the M8 oil pump back cover O-ring/seal groove, we’ve 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. 538 CAM - Aggressive camshaft with a "nasty" sound. This camshaft revs up fast and pulls hard in engines with big bore cylinders, modified cylinder heads, inake, compression and exhaust. The REAPER 538 grind will shine in 124" and larger cubic inch engines with added compression ratio. Ported cylinder heads are not required but will complement the cam and add even more pulling power throughout the range. The stock throttle body produces an excellent powerband and use of a high flow throttle body will increase peak power numbers. A high flow exhaust system and air cleaner is highly recommended for optimal performance. FEULING recommends matching this cam with our RACE SERIES oiling system. NOTE: High Lift valve springs are required on stock cylinder heads, see FEULING BEEHIVE valve spring kit #1107 or #1108. SE cylinder heads have high lift valvesprings but will need to be verified. Heavy Duty one piece pushrods are also highly recommended see #4087. Part # 1351 RPM range 2,350 - 5,975.

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 M8 front exhaust camshaft lobe flange. 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.
