Don't forget to buy a window piston! Must be used for maximum performance with reed valve and ported cylinder.
Many companies do not properly port cylinders for use of reed valves. WE DO! The new GTZ race cylinder is fully decked out for use with reed valves in high performance setups. You must use a window piston to take advantage of this cylinder's full potential.
