Feuling, M8 Race Series lubrication system. Gear or chain drive

For chain or gear driven camshafts.
Includes cam change gasket kit.
With short travel tappet set. Feuling's 'Short Travel' Race series tappets have a shorter travel (0.115"), keeping the engine quiet. The reduced travel decreases the amount of pushrod bleed-down and the oil needed to fill the inside of the tappet, reducing oil aeration inside the tappet on fast-acting, high-lift camshafts.
The kit includes everything needed to rebuild the lower end. Oil pump, camplate, lifter block/rocker arm assemblies and gasket set. Great improvement and perfect foundation when fitting a set of high-performance camshafts.
The kit includes: cam change gasket and seal kit 588035, Race Series tappet set 707358, Race Series oil pump 707379, red anodised high-flow cam plate 588056.
The FEULING CENTER/WATER COOLED RACE SERIES oil system kit with short travel lifters combines all the components needed to complete the lubrication system of your M8 engine under a single part number. FEULING oil system kits increase oil pressure, oil volume, engine oil flow and oil return scavenge.
• Quieter and smoother engine operation • 30% more pressure gear volume than stock • 53% more suction gear volume than stock • 46% more oil volume to the crankshaft and connecting rod bearings • Engine temperatures 15-25 degrees cooler • Oil temperatures 15-30 degrees cooler • 10-30 PSI additional oil pressure • Reduces oil pooling in the crankcase, blow-by and oily air filters • Test results show a gain of 2 HP and 2 ft/lbs of torque at the rear wheel on the Milwaukee Eight • NOTE: FEULING tests show up to a 50% reduction in engine crankcase oil level.
The RACE SERIES kits include: RACE SERIES oil pump, RACE SERIES short travel hydraulic lifters, high flow camplate and camshaft installation kit, camshaft bearings, camshaft/crankshaft bolts and washers, engine assembly lubricant and fasteners.
The FEULING high-flow forged camshaft plate is made from 7075 aluminium, which is 50% harder and stronger than factory camshaft plates. FEULING increases oil flow and volume by enlarging the oil pump reservoirs and critical oil passages, including matching the oil port holes throughout the camshaft plate with the port holes in the engine case, which increases engine oil flow to the lifters, piston cooling jets, crankshaft and connecting rod bearings.
FEULING oil pumps are bench tested; the relief valve is seated and sealed at a minimum of 30 psi with full opening at 55-60 psi. The greater oil volume from the larger gears and properly sized passages, together with the pressure relief valve seat and seal of these oil pumps, is essential for correct lubrication system operation. The combination of the FEULING oil pump and cam plate eliminates the common pressure and scavenging issues associated with factory lubrication systems.
Due to the high volume of calls and enquiries requesting the groove for the seal/O-ring on the M8 oil pump rear cover, we have added the groove (11/05/21). Although Feuling's in-house testing on healthy engines showed no benefit. The O-ring may have potential benefits in certain circumstances, such as engines with higher cylinder compression loss, poor subsell O-ring sealing, elevated crankcase breather hole and/or crankcase plug (see M8 PRO TIP below) and wider clearances between the lifter and lifter bore.
- RACE SERIES kits include a hard-anodised 7075 forged oil pump, which is 50% harder and stronger than the factory pump, maintaining tighter tolerances under temperature. M8 RACE SERIES oil pumps have deeper suction kidneys compared to the HP+ kidneys for greater suction volume.
The RACE SERIES short-travel hydraulic lifters have a total travel of .115", designed with a slower bleed rate to handle high valve spring pressures, increase engine RPM before valve float, and feature greater roller clearance for camshafts with steep ramps and clearance for the front exhaust lobe flange of the M8 camshaft.
FEULING short travel lifters See one-piece pushrods for use with short travel pushrods:
(Part # 4088 for use with factory base circle camshafts with Feuling short-travel lifters. Includes Feuling 405, 465, 472, 508, 521, 592 cams) # 4088 HP+ one-piece pushrods, 0.165" wall thickness, +0.040" longer. Fits: M8 '17-20, with
-#8022: Optional ARP bolt kit for the FEULING high-flow cam plate #8017 and HP+ or RS oil pump combination available. The ARP bolts for oil pumps 7018, 7019, 7020 and 7021 do not use washers.
OIL LEVEL NOTE - DO NOT OVERFILL THE OIL TANK It is important to achieve the correct hot oil level on your motorbike. Feuling recommends keeping the oil level at 90%-99% of capacity when hot.
Note: The M8 oil scavenge port is on the right-hand side of the engine. Letting the bike idle or warm up on its side stand will naturally raise the gearbox housing level and skew the oil level in the tank.
We recommend the following steps to achieve the correct oil level:
1. Check the oil level when cold.
2. Ride the motorcycle until it reaches operating temperature.
3. Switch off the motorbike while it is still in an upright position. (This ensures an accurate reading) 4. Once the motorbike is on its side stand, check the oil level.
5. Add or remove oil as necessary.
