Through extensive development, with fl ow bench, dyno, and track testing, we achieved optimum power from our GYTR ported cylinder head. Once we perfected the head fl ow characteristics, we meticulously digitized the ports to obtain the precise dimensions needed for CNC machining. Unlike fl ow variations inherent in hand porting, CNC porting lets us accurately reproduce this maximized fl ow design with every cylinder head manufactured. Cylinder head comes as a ready-to-install assembly, with valve train and GYTR Performance Camshafts pre-assembled. Can be used with stock or GYTR performance piston (GYT- 5D305-00-00), sold separately. Used by ITP® QuadCross® Champion Dustin Nelson.

This accessory is restricted to closed-course competition only For maximum performance and protection, always use Yamalube 15W-30 Full Synthetic Oil after installation – two quarts are included with each GYTR Ported Cylinder Head Assembly.
