Throttle spring tension

Is there a way to releave some of the throttle spring tension on these ? I’ve busted the factory cable and pulled this one apart twice . Is there a reason they’ve made these spring with such a hard pull? And no there not binding anywhere and geometry seems correct. Thanks for any info

At your own risk.  This is a common complaint with the 2x4 setup.  I have seen guys take a full turn out of the spring tension.  Never done it myself.  But I hear it works....

Must disassemble the linkage to accomplish.

Worked like a charm, took one turn out of front primary , left rear alone and way less pull on cable, Thanks , Greatly appriciated.
