NEW CNC CHAMBERS 119cc - Flow More Air - Makes More Power
CNC Chambers helps the head flow more air by un-shrouding the valves at low and high lifts. Also all the chambers are exactly the same which makes it easier to tune for maximum power. Intake ports flows up to 5% more and exhaust ports over 25% more with CNC chambers which equals substantial increases in horsepower.
