Built to only the highest standards, you will not need to modify this head further as all the work has already been done for you. The intake inlet ported to a "8" shape for optimum airflow. Advantages include : Heat resistance especially at high temperatures , maximized flow of air , fuel mixture and an oval shaped exhaust port to name a few.

Ideally made to go with the 62mm big bore cylinder kit from UMA with domed forged piston, you can also mate it with kits from other brands.

*Minimum piston size 57mm* 

Included with this item are the valves, titanium retainers, springs, rocker arms already assembled. Also gaskets and a matching camshaft. Basically everything you need for assembly, good to go.

This cylinder head is plug and play for 14+ Yamaha non-VVA engines with o2 sensor bung at the exhaust port. For early models with o2 sensor bung, please check out the other V1 version of this cylinder head.
