•  Heat-resistant steel valves.

•  An equal pitch valve spring has been adopted.

•  An cast iron alloyed valve guide with excellent abrasion resistance has been adopted.

•  Part of the exhaust valve stem is narrow, functioning as a carbon cutter. Due to this, the valve guide has no carbon cutter and is common to the intake and exhaust.
