[605-64098-2]

This 3.0mm oversize 47mm intake valve improves the inlet flow and helps fully charge the cylinders.

Requires replacing stock seat with special alloy oversize seats.  See Part #605-79204-2.

You can leave the exhaust at stock diameter of 38mm or change to our light weight 38mm special race valve, PN 605-12751-1.

18 grams lighter!  Stock 110g...this valve 92g.  Reduce valve spring pressure and gain HP!

This is a combination that Jim K recommends.
