• 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.
