⚙️ The Race Series® Camchest Kit with Short Travel Lifters delivers high-volume oiling, reduced valve-train harmonics and improved engine reliability for M-Eight engines. Ideal for riders seeking cooler oil and engine temps plus increased oil pressure and scavenge flow.
- Billet 7075 aluminum oil pump, which is 50% harder and stronger than the factory pump, holding tighter tolerances under temperature.
- Short travel hydraulic lifters have 0.115" of total travel and will increase rpm by decreasing valve float and valve-train harmonics while maintaining a quiet engine.
- Deeper scavenge kidney ports over the HP+ series for even more scavenge flow volume.
- 30% more pressure gear volume over stock for M-Eight Twin-Cooled motors; 53% more scavenge gear volume for M-Eight Twin-Cooled motors.
- 27% more pressure and scavenge gear volume over stock for M-Eight Oil-Cooled motors; 42% more scavenge volume with port sizing, matched passages and holes to the engine case for M-Eight Twin-Cooled motors and M-Eight Oil-Cooled motors.
- 68% more oil volume to the crankshaft and connecting rod bearing for M-Eight Twin-Cooled™ motors and M-Eight Oil-Cooled motors, yielding 15°–25° cooler engine temperatures and 15°–30° cooler oil temperatures.
- 10–30 more psi of oil pressure for M-Eight Twin-Cooled™ motors and M-Eight Oil-Cooled motors; increases oil pressure, scavenge volume and engine oil flow; reduces wet sumping, blowby and oily air cleaners.
- Magnets in the oil pump to help protect gears and the pressure relief valve.
- Test results show a 2 hp gain and 2 ft/lb of torque gain to the rear wheel on M-Eight; Feuling test results show a 50% reduction of engine sump oil level.
