Going to 4 springs is not the answer. You can take a spring out and measure it and order a lighter spring from several spring mfg`rs. Inside, outside, total length, collapsed length, number of coils and spring diameter. Takes some experimentation, but worth it. I just spent two days making the perfect clutch for me on my beta. I lost my tendon in the tip of my clutch finger at Christmas. After 40 yrs I just cannot get my middle finger to work instead of my index finger.
