im not familiar with misumi springs. im using austria made spring gauge 21 3/8 od for valve,5/16 od for hammer. are you certain with your hammer weight? mines only 50gms.
valve n hammer spring combination/tension is a trial n error procedure its up to you.everything must be considered to achieve a perfect tune eg hammer travel,valve duration,valve seat size,tranfer port size.
