This listing is for a set of new titanium intake and exhaust valves for the Yamaha XS650 custom made to order. Please specify desired head diameter and any custom length/keeper groove requirements you may have for various spring/retainer combinations. Intake valves have 20 degree tulips and exhausts have 30 degree tulips by default but that can be customized as well. These valves feature hardened steel tips so no lash caps are required. Valve stems are CrN coated for long wear life and hollow for further reduced weight.  Manufactured in house from new Delwest blanks. Please allow 1-3 weeks lead time.
